Where I live all of the chemicals and glassware are legal and bought from chemistry companies' outlets. The only one I suppose would be okay to sell abroad is:>1g lab grade (merck) 10% Pd/C (stored in an amber glass vial)Then about the reagents... there is something basic like:>Formic acid>c.

Pure Oxycodone Synthesis - My Tek View Thread Reply Hide Bombastus !!HToBa9dh - Sun, 10 May 2015 19:27:27 EST 4ppVjZXo No.76494 File: 1431300447686.png -(3571B / 3.49KB, 451x323) Thumbnail displayed, click image for full size. This was my old one. I'll post it up here in case anyone is interested/ can make corrections on it. If you want clarification on anything, let me know. The hydrogenation (i think) will be the hardest part for any home chemist, let alone kitchen chemist.The benefit of this synthesis is that it has no toxic chemicals, doesn't use chromate intermediates, and is made from relatively easy to acquire chemicals.The downsides are that it requires a lot of chemical knowledge, knowledge on desiccant formations, and is much slower than the sodium dichromate method I have seen used (two refluxes that take up 24hours each are used)Cod - CodeineCodo - CodeinoneOxo - OxycodoneWorkup of Aluminium IsopropoxideIn 250two neck RBF, set one neck up for reflux and one neck up for desiccation. Prepare a drying tube with CaCl2 and link it up to the vacuum adapter in the desiccation neck. Heat all the glassware to an ambient temperature of 80deg C upwards towards the allihn condenser. Proceed to blow air through the drying tube into the flask. Seal off the allihn condenser with a small amount of aluminium foil. Desiccated aluminium dust (27.98g, 1.00mol) is ground to remove oxide layer and HgCl2 (0.01g) was added. The metal semi-amalgam is added to the bottom of the flask and desiccated isopropanol (250ml, 3.30mol) is injected carefully into the vacuum adapter septum. The vessel is left to reflux for 4 hours.While still on reflux, the allihn condenser is removed and a 3-way adapter with a thermometer adapter is quickly added. The vacuum is attached to the receiver joint of the 3-way with a one neck 250 RBF while stoppering the side arm of the two neck flask tightly. A distillation is run until only solid aluminium dust remains in the still flask. A yield of 80% of 1mol aluminium isopropoxide (163.4g) should be achieved.Oxidation StepIn the same receiver flask of anhydrous aluminium isopropoxide, a desiccated solution of Cod in 100ml of toluene (6g, 20mmol) is added to a solution of aluminium isopropoxide (8.17g, 40mmol) and dried cyclohexanone (9.8g, 100mmol). The receiver flask was set up for reflux and heated for 24 hours.After cooling the solution to room temperature, 50ml 2.5M hydrochloric acid was added to basify the Codo to Codo HCl and destroy any remaining aluminium. The organic layer was separated and washed with 2 x cc. of water; this layer contained toluene, cyclohexanone, cyclohexanol, and isopropanol. The aqueous layer was combined and 50ml 5M NaOH was added dropwise. The basified solution was washed with 3x 20ml DCM. The DCM was dried under magnesium sulfate and let to evaporate yielding Codo freebase.9th Hydroxide/ Hydrogenation 1-pot, 2-step ReactionIn a 100ml RBF, 5g of Codo is combined with 10ml 80% formic acid, 5ml 30% hydrogen peroxide, and 1.5ml water. The flask is equipped with a allihn condenser and heated in a water bath at 55° C for 8 hours.The reaction is taken off heating and cooled in an ice bath to 0° C. 0.5g of palladium chloride is added to the solution and is hydrogenated at 5atm for 24hours. The resulting Oxo solution is basified with 40ml of 30% sodium hydroxide and washed with 2x20ml DCM and 2x10ml diethyl ether. The DCM and ether solutions are dried independently to yield pure Oxo freebase. 107 posts and 5 images omitted.

The autoclave was evacuated and filled with hydrogen. The mixture was mechanically agitated at ambient temperature (25–29° C.) while the hydrogen pressure was maintained at 19–38 psi until the pressure drop caused by the hydrogen consumption stopped. Cyclohexane (120 mL) was charged into the autoclave followed by solid potassium tert-butylate (16.22 g), the mixture was mechanically agitated under nitrogen at ambient temperature for overnight, and then quenched with 1.5N acetic acid (150 mL) with mixing and cooling in the ice bath.

At what speed (MPH or KPH) does aerodynamic drag become a factor for various items?I know that for automobiles drag becomes a factor when you're in the 30-40mph ballpark, but what about bicyclists or runners? It's easier to determine the coefficient of drag of, say, an airplane or a car because they're (more or less) static objects, but a cyclist moves their legs and a runner moves their legs and arms. I'm wondering about this because when I'm on a stationary bike, I'm able to pedal faster with more power when I'm in the typical forward fold versus when I'm pedaling upright-- aerodynamic forces are pretty well negated in this case. The same thing goes for running-- if I'm jogging upright on a treadmill versus leaning forward, I produce more power and speed when I'm leaning forward because my center of gravity has shifted-- but does leaning forward provide any specific aerodynamic benefit for anyone who isn't running as fast as Usain Bolt? >> Nell Hagglestat - Sun, 17 Apr 2016 15:28:41 EST 6SGTYI6Z No.77850 Reply Sounds like a difficult question to answer, but if you're running on a treadmill then do aerodynamics even matter?

I realise that this board is mostly used for instructions on how to make drugs in your fucking garage, but since this is also a science board I thought that I would ask you brilliant minds for help. I have a upcoming project, spanning a year or so, that will entail/connect almost every course I am taking. I am supposed to pick something to create, experiment, etc. and present the result to my professor(s) and peers. I have seen dudes investigate pharmacuticals, tried to treat salmonella by destroying its flagella with enzymes, etc.What the hell am I supposed to do?

Hey guys,I want to get into chemistry. Can you recommend some good, free online courses or something? Or maybe some book(s) that is good for a self-learner? The site study.com offers a free 5 day trial (afterwards the cheapest thing is $50/month which isn't bad), I will give that one a go. On this other site, alison.com are some free courses of introduction to chemistry, which is exactly what I'm looking for, but it looks like these are only videos, I'd rather have something like videos and presentations/written text so I can re-read it and learn it.. you know, just like in college. Yeah I could make my own notices while watching the videos but fuck that noise, I hate making notices.

I remember as a kid I used to mix mr muscle containing NaOH, aluminium and water. A strong exothermic reaction occurs by mixing the NaOH and water. Adding the aluminium instantly reacts with the solution and creates hydrogen gas. Me and my friends had a blast doing it when we compressed it in a regular old plastic PET bottle (get the pun?) Are there any similair experiments that causes the same kind of explosive result (made from homemade stuff of course)?I've heard something about El Dorado soap but idkI can't really make nitro glycerin like that cool youtube chemist because I don't have access to nitric acid, etc.And no, officer, I am not a terrorist 2 posts omitted.
