Department of Chemistry and Chemical Engineering, Taiyuan University of Technology, Taiyuan 030024, China)Р Abstract: Methyl 3-hydroxypropanoate was prepared by hydroesterification of ethylene oxide with carbon monoxide in theРpresence of Co2 (CO)8 catalyst and methanol. The effects of ligands, carbon monoxide pressure, reaction temperature and time on theРyield and selectivity were investigated. When Co2(CO)8 liganded with 3-hydroxypyridine was used as catalyst, under 7.5MPa of carbonРmonoxide at 75 ℃ for 4 hours, the selectivity and yield of methyl 3-hydroxypropanoate were 95.7% and 64.0%, respectively.Р Key words:ethylene oxide; methyl 3-hydroxypropanoate; Co2(CO)8; hydroesterification
