作者以价廉易得的苯酚为原料制得苯氧异丁酸,在催化剂存在下氯代得对氯苯氧异丁酸,再经卤化、酰化和Mannich反应制得氯丁吗脲。步骤缩短,原料阶廉易得,具有实用价值。
The authors made phenoxyisobutyric acid from cheap and cheap phenol as the raw material. Chlorinated phenoxyisobutyric acid was obtained by chlorination in the presence of a catalyst. Chlorophenoxyisobutyric acid was obtained by halogenation, acylation and Mannich reaction. Shorten the steps, the raw materials cheap, with practical value.
