METHOD OF SELECTIVE PHENYLACETYLENE HYDRATION IN PRESENCE OF STIROL Russian patent published in 2014 - IPC C07C15/46 C07C7/167 C07C5/09 B01J21/18

Abstract RU 2505519 C2

FIELD: chemistry.

SUBSTANCE: invention relates to method of selective phenylacetylene hydration in presence of sterol, which includes contact of hydrocarbon raw material fraction, which contains phenelecetylene and sterol, with carbon-containing catalyst under conditions of hydration reaction. Content of carbon in carbon-containing catalyst constitutes 0.02-8 wt % with respect to catalyst weight.

EFFECT: method makes it possible to remove phenylacetylene with high degree and low loss of sterol.
