| Application | cyclopropylamine is an important intermediate in the synthesis of quinolones such as ciprofloxacin and enrofloxacin, and is also used in the preparation of pesticides and dyes, there is a greater demand in the domestic and foreign markets. |
| Use | cyclopropylamine is an intermediate of the herbicide cypromazine and the insecticide cyromazine, and is also a pharmaceutical intermediate. cyclopropylamine is mainly used in organic synthesis, pharmaceutical synthesis intermediates, can be used for the synthesis of new antibacterial drug ciprofloxacin products, such as the synthesis of ciprofloxacin, enrofloxacin, sparfloxacin and other drugs. In addition, cyclopropylamine is also an important intermediate for the synthesis of pesticides, plant protectants and herbicides, such as 2-chloro-4-6-cyclopropyls-triazine, cyclopropachlor, cyclopropanine, cyclopropanosine and other cyclopropyl pesticides. |
| production method | cyclopropylamine has a variety of synthetic routes:(1) 1, 3-propanediol as raw material, cyanation, cyclization, amidation, Hofmann rearrangement products;(2) gamma-butyrolactone as raw materials, by high pressure chlorination, esterification, cyclization, aminolysis, Hofmann degradation products;(3) with ethyl acetoacetate as raw material, the product was obtained by condensation and cyclization with ethylene oxide, ring-opening and re-cyclization, oximation, rearrangement and degradation. (4) 50% NaOH, sodium hypochlorite solution and cyclopropylcarboxamide were preheated to 80 ° C. And passed through a reaction tube to obtain cyclopropylamine. |
| autoignition temperature | 527 ° F. |
