The present invention relates to a process for preparing vinyl carboxylates, wherein a carboxylic acid is reacted with an alkyne compound in the presence of a catalyst which is selected from carbonyl complexes, halides and oxides of rhenium, of manganese, of tungsten, of molybdenum, of chromium and of iron and rhenium metal at a temperature of ≦300° C.
The process gives the desired vinyl esters with high yield.
本发明涉及一种制备乙烯羧酸酯的方法,其中在选择自钨、钼、铬、铁和铼的羰基配合物、卤化物和氧化物作为催化剂的情况下,将羧酸与炔烃化合物在温度≦300°C下反应。该过程以高产率给出所需的乙烯酯。
