Procedure

A mixture of 34 grams of tetrachloroterephthaloyl chloride in 85 ml. of tetrahydrofuran and 100 ml. of dioxane are charged to a 500 ml. flask. About 75 grams of ethylene glycol is added dropwise to the solution. This is followed by dropwise addition of 20 grams of pyridine over a period of one hour. The reaction mixture is stirred for 24 hours, and then the volume concentrated by distillation up to a temperature of about 120° C.

Workup
