The present invention relates to a process of hydrogenating an aIkynoI selectively to an alkenol by hydrogen using a hydrogenation catalyst which is palladium supported on a carrier in the presence of an additive which is an organic phosphorus compound bearing either a phosphine or a phosphine oxide group and with the proviso that if the additive bears a phosphino group that the additive bears two or more phosphino groups.
本发明涉及一种利用
钯负载在载体上的氢化催化剂,在有机
磷化合物作为添加剂的存在下,通过
氢气选择性地将
炔烃氢化为烯醇的过程,其中该有机
磷化合物带有膦或膦氧化物基团,但需注意如果添加剂带有膦基团,则该添加剂需带有两个或更多膦基团。
