摘　　要：Racemic α-(isopropanyl)-p-chloro(fluoro) phenylacetic acids were resolved with a precipitation method using α-methylbenzylamine as precipitant. The process is easy to handle and less time-consuming. The yields were about 38 % with 98 % optical purity.Racemic α-(isopropanyl)-p-chloro(fluoro) phenylacetic acids were resolved with a precipitation method using α-methylbenzylamine as precipitant.
