Used to prepare medicines, fungicides, insecticides, etc. Organic synthesis, epoxy curing agent, rubber accelerator, inhibitor. Storage: The warehouse is ventilated, low temperature and dry; store it separately from oxidants and acids. Other: Pyrrolidine, also known as tetrahydropyrrole, is a colorless to slightly yellow liquid with a pungent ammonia odor. It fumes in the air and is toxic. Strong alkalinity, miscible with water, soluble in ethanol, ether and chloroform. Pyrrolidine can be synthesized by catalytic hydrogenation. Pyrrolidine is a natural substance found in tobacco and carrot leaves. The molecular structure of pyrrolidine is a cyclic secondary amine, and its reaction is the same as that of ordinary amines. Pyrrolidine is an important organic chemical raw material that can be used to prepare drugs, fungicides, insecticides, etc. Preparation: 鈶?Using 1,4-butanediol as a raw material, dehydrating to produce tetrahydrofuran, and then reacting with ammonia to produce pyrrolidine. 鈶sing furan as raw material, reacting with ammonia at 400掳C under the action of a catalyst can produce tetrahydropyrrole. 鈶?Using 1,4-dichlorobutane as raw material, reacting with ammonia, pyrrolidine can be obtained. 鈶?Tetrahydropyrrole can be obtained by reduction with pyrrole as raw material and ruthenium or rhodium as catalyst.Organic Intermediate price website:http://www.flgchem.com/organic-intermediate/
