If Ti has the follow electron config as a base config: (where ^ represents an e-)

^^ ^ ^
4s 3d 3d 3d 3d 3d

would it hybridise to the following (to accommodate (Cl-)4)?
^ ^ ^ ^
sp3d sp3d sp3d sp3d sp3d

leaving it with a final config of (with bonded (Cl-)4):
^ ^ ^ ^ ^ ^ ^ ^
sp3d sp3d sp3d sp3d sp3d

thereby classifying it as a lewis acid because it can accept a lone pair?

fuck that formatting did not work
to clarify
first example: essentially the 4 of the 5 sp3ds would have 1 electron in each
second example: 4 of 5 sp3ds filled due (Cl-)4 electrons and last orbital unfilled, allowing lone pair acceptance

is this right?

hey man not sure im following you exactly, but it would be much easier to think of this in terms of CFT/ligand field model, as in 4 M-L bonding interactions lying lower in energy than the metal based d-orbitals (e and t2 sets) which have an occupancy of 4. Electronically speaking TiCl4 has low-lying MO's, of primarly Ti character, so yeah it is fairly electrophilic and a decent lewis acid. evidenced in that it happily forms adducts with donor solvents such as THF

Well I was ready to reject chemistry outright, especially after Captain ChemE-Cunt showed up. But I dunno. You forced me to confront a truth about my path in life. I don't believe I'm any sort of gift to chemistry; there's no nobel prize in my future and I'm no genius. But I know I'm more than this.

It's a bit painful to see my creativity used for something as frivolous as the structural integrity of concrete surfaces. It's even more painful to see that frivolous innovation generate millions of dollars for someone else while I see the equivalent of bread crumbs for my efforts. I understand that there's sales, marketing, processing, and manufacture to consider as well, but it's my formula and my customized process that allowed the rewards to be reaped in the first place. Hell, I basically optimized their entire manufacturing process for these products; wrote all the batch tickets for them, all the pds sheets, all the sds sheets, I mean that product line is my fucking brain child. And oh yes, I feel the appreciation. I get so many pats on the back I have bruises. But monetary compensation? Ohh no, I'm at market value. Someone with A MASTERS (OMG) will accept my wages, and so I am pretty much at my peak value.

What a fucking joke.

They don't take into consideration that someone with a masters in chemistry may not have the talent to formulate their products. And even if they do, it would take years to even get to the understanding I have now. I'm confident that anyone with a higher level of insight into my field would request more than what they can offer me.

I guess all my woes may just stem from a shitty company; I got the job before I even graduated with my Bachelor's at a construction chemicals manufacturer and revamped a failing product line within 2 years. The knowledge I learned was from my own diligence and study. No one taught me anything about the science behind the products because there was no one there who understood the chemistry.

We took market leadership with first baby; it's quadrupled in sales volume since my revisions. After a few research successes, they divided my other duties among 2 other people and gave me a full time research position. And you know, creating shit is great, especially shit that people need and will use. I love that people need what I design and will choose it over other products in the market. I guess I just feel like I'm just trading my ideas away.. a part of me away, in exchange for a meager allowance. I know the financial impact of my designs because I design my products around their financial impact.

Basically I'm just disappointed in my experience with the chemical industry. And I understand that this small company may not be representative of the industry. I hope it's not.

in a context of conducting a synthesis, does it matter whether a reagent is in a form of a salt or not? can you even make such a general statement?

i'm asking because im interested in the chemistry behind converting codeine phosphate to morphine. does it matter whether someone uses codeine phosphate or codeine freebase?

Ah, I see. I thought you were doing a reaction with the codeine phosphate and wanted to know what you were doing with it.

In most reactions, you'll have to only calculate the moles in the weight as 30mg of codeine does not mean 30mg of pure codeine. Rather, they include the phosphate weight as well. 30mg of codeine anhydrate has 30mg of codeine in it. 30mg of codeine phosphate has 20 something mg of codeine and like 7 or so mg of phosphate (too lazy to do that math - you figure it out).

It will matter in some water sensitive reactions and depending on the ion exchange, it could matter. But in most cases involving a base, the phosphate would be generated anyway.

Depends on the solvent your going to carry out your reaction in. In most cases i can think of the freebase is required. Careful, codeine is easily destroyed by strong acids and bases. Hell, even heat and a little too much ammonia will do it. Also too much water and it will stay in the aqueous layer. Work as small as you can because 9 times of of 10 you will have failures.

codeine 300g/mol
codeine phos 397g/mol
ammonia 17g/mol
sodium carbonate 106g/mol

0.001mol 1mmol codeine phosphate = 397mg
add 1mmol ammonia = 17mg or 170mg 10% ammonia
or add 0.5mmol carbonate because there are 2 sodiums = 53mg
and you should be left with 300mg codeine

In reality you will likely need a little more base in many cases, but it gives you a general idea how much to start with.

Coffee Filters are best, fine scientific filters tend to filter rather slowly. If you are working with Ibuprofen, you're better off decanting - it is heavy and highly insoluble even at room temperature, so it will form an adhesive block at the bottom of the container that won't fall out even when tilted at a strong angle. Paracetamol is a bit more awkward.

I've gone through this process to convert salts -> freebase by:
adding some salt drug to a lye solution then using hexane to pull the freebase and evaporate.
My question is: while this process seems to have to have worked with a 2C and with U-44770, can you think of any case where the NaOH will mess up the drug somehow? Or a case where the freebase won't dissolve in the Hexane?

2) Is acetone good enough for purifying most drugs? How are you even supposed to know the solubility of a lot of these new drugs like 4-methyl-pentedrone or 3-Fluorophenmetrazine? Acetone is used for MDMA and Ketamine purificaiton, so what stuff does it NOT work on?

Hi all,

I hope I'm asking this in the best spot & really hoping someone can assist me w/this......

So I'm getting ready to try ULDN for the 1st time, that is if I can get this figured out. So I thought I added my 50mg tab of naltrexone to 1 liter or 1000mls of water however I didn't look close enough at the bottle I'm using, duh I know. Anyhow instead of 1 liter the bottle I added everything into is 1.25L.
So I'm trying to figure out how many mcg's I have per ml. The recipe I followed has the dosages based on 1 ltr not 1.25 ltr. Considering this is touchy & the dose is based on mcg's I wanted to verify what I now have w/some folks that are way better in the chemistry & mixing department.
I would be very grateful for any info you may be able to provide. Anything you also may like to add about ULDN would also be greatly appreciated.

Thank you!

Your solution contains 0.04mg per mL or 40microg per mL

But i doubt that the volume of your bottle was very accurate.

Isnt the solution going to perish? Depending on the pill contents it might spoil quickly

Thanks for your reply. I don't know how fast it will perish. I've read that w/refrigeration it can last a month or 2. Just have to make sure I order more long before I run out. I think I'll try cutting the next tab in half & mixing it w/ 1/2 the amount of water. I know it's only been less than 48hrs but so far this is amazing. I wasn't exactly sure how much I diluted the recipe I followed down so based on the original directions I've just been using 5-7 drops w/each dose of opi's. The analgesia & duration of how long they last is pretty amazing. I wish more people talked about this.
Anyhow thank you so much for replying, it is greatly appreciated.

Happy, almost, Thanksgiving.

you might want to either get a volumetric flask, which might get expensive i dunno, or find a bottle with which you can very accurately measure a set volume. ideally it would be a bottle with a very thin neck, which would be filled to a certain level of the neck

if your solution is really mixed and the naltrexone is readily water soluble you could store it in several small containers while frozen. then youd simply have to take out a single container, thaw it and shake it before use while the others still remain frozen.

any idea how big one of your drops is? or how much one drop weighs?

I don't have any fancy measuring bottles, can you suggest somewhere I could find one in expensively? The recipe I'm following is to mix 1 50mg tab into 1L but it makes a huge amount. I was thinking to see if I could cut a tab in half or even quarters, cut the water down accordingly but I'm afraid of possibly not cutting it perfectly in half or quarters each time. Your idea of storing in the freezer is great! I was afraid the solution would go bad before I'd ever get thru an entire liter. Even though the naltrexone tabs were easy enough to get I'd prefer not to waste them. I found it odd that w/each study or recipe I found nobody talked about properly storing the mixture or preserving it aside from putting the mix in an amber or cobalt glass bottle or storing in the fridge.
Do you think freezing the mixture would degrade it in any way? Do you know if the mixture is sensitive to light?
I did get a couple different syringes from the pharmacy, 1 I think is useless for dosing anyways, it's more of a child's medicine dropper, 5mls w/o small enough increments for dosing, maybe good for something else. The other syringe is 1ml, has .10 increments & even smaller. I just tried counting how many drops a full ml holds & came up w/30 almost 31 drops. One study & recipe I read said their 1ml dropper held a perfect 20 drops. Not sure what they're using but I tried several times & came to 30-31 each time.
With the recipe I'm following it says that what I should end up with is 50mcg per 1ml & .2 ml = 10mcg. Because I accidentally didn't see the bottle I'm using is a 1.25L instead of a 1 L my drops are slightly diluted. I found a couple other recipes but they're all relatively the same.
The naltrexone tabs I got dissolve very fast & completely in water. One recipe said not to shake the tab in the bottle, that made no sense to me since you want to make sure you have even doses. Another recipe said to shake it vigorously, I did the latter. When I dropped the tab in the water I just left it to dissolve while I ate dinner. When I came back it had totally dissolved on its own w/just an uber tiny amount of p…

i dont really see how using amber or colbalt glass bottles would help, those are normally used for light sensitive stuff but im not sure about naltrexone being light insensitive. my bet would be that it shouldnt be, since ive never heard of morphine or oxymorphone are. its not going to degrade when its frozen, but be sure to really give it a good shake after dethawing it. use plastic bottles for storing it frozen. ive seen quite a few phds fucking that up once in a while.

for measuring the final dose a syringe is good
the size of a drop also depends of the diameter of the opening so its not a suprise they found some other ratio. i have no idea about ultra low naltrexone, once read that it can reap lotsa benefits but i dont remember the dosage tl;dr cant get lantrexone anyways

i guess the particulate is some gunk like magnesium stearate or some other stuff they put in to make the pill super duper
no biggie, you have a nice one too

Do you know about any program that can be used to simulate chemical reactions?
What is your opinion about it? I recently stumbled upon "Cain" but still haven't learn to work with it.
