How to Make MethamphetamineMethamphetamine illicitly prepared via active metal/ammonia (Birch) reduction of ephedrine or pseudoephedrine is commonly contaminated with 1-(1′, 4′-cyclohexadienyl)-2-methylaminopropane (CMP), often in significant amounts. LargeDEA Birch...
CO + 3 H2→ CH4+ H2O. To produce the desired end-product ammonia,the hydrogen is then catalytically reacted with nitrogen(derived from process air) to form anhydrous liquid ammonia. This step is known as the ammonia synthesis loop (also referred to as the Haber-Bosch process): 3 H2+ N2...
“Birch conditions” in general will alert you to expect liquid ammonia, just as “anhydrous conditions” means not to let any water in by means of drying everything. I wish I wrote like a chemistry author. I had thought of a chemistry word which would make me sound smart, but I ...
Refrigeration designers for ice-skating rinks operated by the city of Montreal said that they were able to reduce the systems' ammonia charge through a design that uses a liquid leg raised to the mid-height of the plate heat ... C Dumas,V Santangelo 被引量: 0发表: 2016年 Joining the Cl...
In the Haber process, ammonia is produced according to the following equation: N(g) + 3H (g) = 2NH (g) How many moles of hydrogen gas are needed to react with one of nitrogen? How to make ammonium dichromate What is the volume occupied by 51.0 g of ammonia (NH3) gas at STP?
