CATALYST FOR HYDROAMINATION OF ACETYLENE HYDROCARBONS AND METHOD FOR HYDROAMINATION OF ACETYLENE HYDROCARBONS USING SAID CATALYST Russian patent published in 2015 - IPC B01J29/68 B82B3/00 B01J23/50 C07C7/167 C07C249/02 

FIELD: chemistry.

SUBSTANCE: disclosed is a catalyst containing nanoparticles of a noble metal on a support - mesoporous zeolite-like silicate MCM-41. The noble metal used in the catalyst is nanoparticles of silver metal with size of 2-5 nm, with the following ratio of components, wt %: Ag - 0.5-10, support - the balance. Also disclosed is a method for hydroamination of liquid acetylene hydrocarbons with an amine at 100-150°C in the presence of a silver-containing catalyst Ag/MCM-41, molar ratio of the amine to the acetylene hydrocarbon of 1-1.5:1, and molar ratio of the acetylene hydrocarbon to the silver in the catalyst of 210-1000:1. The amine used is aniline or piperidine.

EFFECT: faster hydroamination as a result of using the disclosed catalyst and high efficiency of the process while maintaining a high degree of conversion of acetylene hydrocarbons.
