AN IMPROVED PROCESS FOR THE PREPARATION OF HIGHLY PURE 4- BROMOPHENYLACETIC ACIDAND ITS INTERMEDIATE

摘要

The Present invention relates to an improved process for the preparation highly pure 4-bromophenyl acetic acid having purity 99.9% starting from 4-bromotoluene, a cheaply available raw material. The present invention is a robust, improved and commercially viable process for the preparation of 4-bromophenyl acetic acid. The present invention also relates to a process for the preparation of highly pure 4-Bromophenylacetonitrile having purity 99.9%.
