Reaction Steps

A solution of 55 g. of this diethyl isophthalate in 140 ml. of ethanol was saponified by the addition of 15 g. of potassium hydroxide in 15 ml. of water. The resulting gel was refluxed 30 minutes, cooled and extracted with ether to remove unreacted diester. The water layer was acidified and the crude acid product precipitated. Ethyl hydrogen isophthalate having a melting point of 131° to 132° C. was obtained in a 16.5 g. yield after recrystallization from benzene.
