КАТАЛИЗАТОР, СОСТОЯЩИЙ ИЗ ПЕРЕХОДНОГО МЕТАЛЛА, НАНЕСЕННОГО НА ДИОКСИД КРЕМНИЯ ВЫСОКОЙ ЧИСТОТЫ, ДЛЯ МЕТАТЕЗИСА ОЛЕФИНА (ОЛЕФИНОВ)

摘要

An olefin metathesis catalyst consists essentially of a transition metal or oxide thereof supported on a high purity silica support possessing low amounts of acidic or basic sites such that in the reaction of pure butene-1 over said catalyst under metathesis reaction conditions the reaction possesses a weight selectivity to hexene-3 of at least 55 wt %.
