摘　　要：综述了苯乙酸的合成工艺路线及其应用。对已工业化的苯乙酰胺法和羰基合成法、氰化钠法进行了比较。指出以羰基钴作为催化剂的羰基合成法为最理想的苯乙酸合成法。建议国内尽快上马羰基合成法生产装置 ;原生产厂家应改造工艺路线 ,采用羰基合成法生产苯乙酸。Some synthetic methods of phenylacetic acid and its uses were summarized in this paper. The industralized methods of sodium cyanide, phenylacetamide,carborylation are compared. It is pointed out that carbonylation process in the presence of cobalt carbonyl is the most ideal one. It is suggested that the installations using carbonylation process will be built with highspeed and the old process of original plants were replaced by carbonylation method.
