Abstract

Hydrogenation of tetrahydrofuryl acetylenic alcohols and acetates in the presence of a supported Pd-containing catalyst has been revealed to proceed at high rate and selectivity to compounds with internal triple bonds. Selectivity in olefin production is 98–99% at the complete conversion of the substrate, the activity of the catalyst varies from 1700 to 13,100 mol/g-at. Pd'h at 20°C and PH 2=0.1 MPa.

Abstract

Проведено гидрирование тетрагидрофурилацетиленовых спиртов и ацетатов в присутствии нанесенного палладийсодержащего катализатора. Показано. что реакция гидрирования протекает с высокой скоростью и селективностью в случае соединений, содержащих внутреннюю тройную связь. Селективность процесса гидрирования по выходу олефина составляет 98–99% при полной конверсии субстрата, активность катализатора находится в пределах 1700–13 100 молей субстрата/г-ат. Pd'час при 20°C и давлении водорода 0,1 МПа.
