ОДНОСТАДИЙНЫЙ СПОСОБ ПОЛУЧЕНИЯ 1,3-ПРОПАНДИОЛА ИЗ ЭТИЛЕНОКСИДА И СИНТЕЗ-ГАЗА С КАТАЛИЗАТОРОМ С ФОСФОЛАНОАЛКАНОВЫМ ЛИГАНДОМ

摘要

Disclosed is a novel class of modified ruthenium catalysts useful in the one step synthesis of 1,3-PDO comprising (a) a cobalt component comprising one or more non-ligated cobalt compounds; and (b) a ruthenium component comprising in major part a ruthenium carbonyl compound ligated with a phospholanoalkane ligand, solubilized in an ether solvent, that provides potential improvements in cost and performance in one step hydroformylation/hydrogenation. For example, cobalt-ruthenium-bidentate, bis(phospholano)alkane catalyst precursors in ether solvents provide good yields of 1,3-PDO in a one step synthesis.
