Abstract

The invention discloses a method for synthesizing isopropamide, belonging to the technical field of synthesizing fatty amine. In order to improve the conversion efficiency and the selectivity of catalysts for synthesizing isopropamide, propanone or isopropanol is used as the raw material, in the presence of hydrogen and a nickel-based catalyst, amination is carried out to synthesize isopropamide under the conditions that the reaction temperature is 110-200 DEG C, the reaction pressure is 0.1-1.0MPa, and the mole ratio of propanone or isopropanol to hydrogen to ammonia is 1:(1-5):(1-5), wherein the catalyst contains a carrier and nickel active components loaded on the carrier, and over 90 percent of the nickel active components are distributed in a region with the depth of 0.7 mm from the surface of the carrier. The method in the invention can ensure that the conversion efficiency of the propanone is improved, has higher propanone conversion efficiency under the condition of same nickel content and better selectivity, reduces the generation amount of diisopropylamine, simplifies the production process flows of the isopropamide, and lowers the production cost of the isopropamide.

Description

technical field

[0001] The present invention relates to a kind of method of producing lower aliphatic amine, more specifically, the present invention relates to a kind of method of producing isopropylamine. Background technique

[0002] Isopropylamine is an important raw material for the production of various pesticides such as atrazine, isofenphos-methyl and buprofezin; it can also be used for the production of detergents such as isopropylamine dodecylbenzenesulfonate; in the rubber industry and It is also widely used in the pharmaceutical industry.

[0003] People have done a lot of research on the production methods of isopropylamine, and some of them have been maturely applied in industry. Wherein mainly contain: (1) isopropanol gas-phase ammoniation method, this method is with isopropanol as raw material, in the presence of copper, nickel or cobalt catalyst, isopropanol and ammonia react to generate isopropylamine under the condition of facing hydrogen, as the United S...
