The most important of the foods are N-Methyl-2-pyrrolidone (NMP), methylformamide, caffeine, ephedrine, and N, N "-dimethylurea. It is also a minor nitrogenous excretion in bony fish.trimethylamines are all produced, and yields are regulated by reaction conditions. They are separated by azeotropic or extractive distillation. Methylamine can also be synthesized by heating ammonium chloride and formaldehyde (Budavari, 1989; Lewis, 1993). Methylamine is listed in the EPA's TSCA Inventory (NLM, 1995). The production capacity If one immediately dumps the reaction mixture onto the stove (skipping the filtering) it takes *hours* (almost days!) to evaporate but 4 moles of methylamine are produced. If you wait for the precipitate to form, then filter it, you get 240-270g of methylamine HCl from 140g of Hexamine.This page allows searching of all reactions involving this species.
