Use	benzylamine is an intermediate for the preparation of insecticides imidacloprid and acetamiprid, and is also an intermediate for sulfamon. use as analytical reagent use as dye and pharmaceutical intermediate . Precipitants for the determination of molybdate, vanadate, tungstate, titanium, cobalt, cerium, lanthanum, praseodymium and neodymium in microcrystallization analysis. Useful as intermediates in dyes, pharmaceuticals, and polymers. intermediates in organic synthesis. For example, benzylamine is acetylated to Acetylbenzylamine. benzylamine is an important intermediate in organic synthesis. In the pharmaceutical industry, it is mainly used for the synthesis of Homo sulfamin and sulfamon acetate (Napaltan In The microanalysis of microcrystallites for the determination of molybdate, vanadate, tungstate, thorium, zirconium, precipitants for cerium, lanthanum, praseodymium and neodymium. Organic analysis is used to distinguish various types of carboxylic acids (reaction with carboxylic acid esters to produce N-benzylamine derivatives, according to the different melting point to distinguish the various carboxylic acids), metal organic compounds qualitative test.
production method	benzylamine can be obtained by reacting benzyl chloride as a raw material with ulotopin, ammonium hydroxide or phthalimide. The preparation method is to add ethanol, urotropine and benzyl chloride to the reaction kettle, heat to 30~35 ℃, react for 4H, add hydrochloric acid, heat to 45~50 ℃, react for 2H, after cooling, filtering, the filtrate is heated and deethanol, and the filtrate is distilled under reduced pressure, distilled to dryness, and lye is added to free benzylamine. After atmospheric distillation, the product is distilled under reduced pressure. Benzyl chloride, ammonium hydroxide and ammonium bicarbonate can also be added to the reaction pot by ammonolysis method, and the reaction is carried out at 30~35 ℃ for 6h. The oil layer is separated by standing, and the reaction solution is heated to remove ammonia gas, and then distilled under reduced pressure at 100 ℃, the free base is then added, the alkaline solution is separated off, and the oil layer is distilled to obtain the product.
