Abstract

The present invention relates to a catalyst for preparing ethylamine, and aims at solving the problems of long reaction period and low ethylamine yield. The solution is to use the catalyst with skeleton nickel as main catalyst, and W and selecting at least one of Cr, Mo, P, B and halogen as cocatalyst. The catalyst is used in the industrial production of ethylamine.

Description

technical field [0001] The invention relates to a catalyst for preparing ethylamine, in particular to a catalyst for preparing ethylamine by hydrogenation of acetonitrile. Background technique [0002] Ethylamine compounds include Ethanamine (or Monoethylamine, MEA for short), Diethylamine (DEA for short), and Triethylamine (TEA for short). Ethylamine compounds are important organic intermediates, widely used in pesticides, medicines, dyes, rubber, water treatment, adhesives and catalysts and other fields. Ethylamine is a colorless and highly volatile liquid, toxic, flammable, and corrosive. It is mainly used as a rubber additive, extraction agent, emulsifier, condensation agent, raw material and reagent for medicine, and is also used in dyes, surfactants, The production of antioxidants, aircraft fuels and lubricants, the most important use is the synthesis of triazine herbicides, including "Atrazine", "Ametryne", "Grassine" "(Cyanagine), "S...
