APAAN conversation with sulfuric acid:
350 ml of concentrated sulfuric acid is placed in a 3000ml flask and cooled to -10°C. The total first crop of moist alpha-phenylacetoacetonitrile obtained according to the procedure above (corresponding to 188-206g or 1.2-1.3 moles of dry product) is added...
Yes
The formulation of extended-release tablets involves specific ingredients and techniques designed to control the release of the active ingredient such as: hydroxypropyl methylcellulose and Xanthan gum
In the reference cited, 3-oxo-N-phenylbutanamide is not mentioned, but the substance that is mentioned is 3-oxo-2-phenylbutanamide (cas: 4433-77-6, alpha-phenylacetoacetamide)
I read that when you cut it with caffeine it increases activity and makes you more social. When I tried it I sometimes feel that way but mostly the amphetamine activity decreases and I feel tired (the amphetamine to caffeine ratio makes a big difference)
Pure amphetamine sulfate is odorless...
I tried the method using sodium methoxide, but after dissolving the sodium salt in water and adding acid, nothing precipitated! . While when using sodium ethoxide or isopropoxide, there is no problem
When mixing ammonium carbonate and acetic acid you will get "ammonium acetate" So the product you will get is P2NP
I don't think zinc will reduce P2NP to P2P.
I read somewhere that Zn\HCl would work but the yield was low
1. Should absolute ethanol be dried? If yes, will the yield be very low if it is not dried?
2. If absolute methanol is used instead of ethanol, does it have to be dried as well? Is the quantity the same as ethanol?
3. The same question for ethyl acetate: should it be dried? I will buy it from a...
Ammonium acetate is easier to synthesize than to dry, so it is better to buy it anhydrous.
I was looking for a way to dry it, but I couldn't find a way that worked for me
I was interested in this product before and after researching I read that it contains 99% nitroethane ( Material safety data sheet )
But I read somewhere on the internet that someone had tried it and said it only contained a small amount of nitroethane (I think 10%).
You just need 640 mmhg
Use (12V R385 DC Diaphragm Pump)
It's cheap and you can get more pressure than you need.
You can also use it to pump water into the condenser
