METHOD OF PRODUCING 2-(2-HYDROXYETHOXY)-ETHANOL ESTER OF FLUFENAMIC ACID

摘要

TITLE OF THE INVENTION: A METHOD OF PRODUCING 2-(2-HYDROXYETHOXY)-ETHANOL ESTERS FROM FLUFENAMIC ACID By using a new method 2-(2-hydroxyethoxy)-ethanol ester is produced from flufenamir acid as a result of direct esterification with diol with an excess of 8-15 mol diol per mol flufenamic acid without concurrent removal of water.
