METHOD OF CONVERSION OF ACETYLENE HYDROCARBONS Russian patent published in 2014 - IPC C07C249/02 C07C7/167 B82B3/00 B01J23/52 B01J29/68 

FIELD: chemistry.

SUBSTANCE: claimed is a method of hydroamination of liquid acetylene hydrocarbons with an amine in the presence of a catalyst under conditions of UHF heating of a reaction mass with the power in the range of 1-10 W at a temperature of 110-150°C in the medium of a polar organic solvent. The catalyst contains nanosized particles of metallic gold on a carrier - titanium dioxide or mesoporous zeolite-like silicate MCM-41. The total content of gold is 1-5 wt %. As the polar organic solvent, for instance, dimethylformamide or a ionic liquid, preferably 1-n-butyl-3-methylimidazolium hexafluorophpsphate, or 1-n-butyl-3-methylimidazolium tetrafluoroborate is used. As the amine, for instance, aniline or pyperidine is used. As acetylene hydrocarbons linear hydrocarbons, for instance, hexyne, heptyne, octyne, and aromatic acetylene hydrocarbons, for instance, phenylacetylene, are used.

EFFECT: reduction of the time of the hydroamination reaction due to the application of polar solvents and UHF heating of the reaction mass and an increase of the process productivity with the preservation of a high degree of conversion of acetylene hydrocarbons.
