실험 절차
Following the general procedure of Example 9, a slurry of 7.13 parts terephthalic acid in 80 parts dry dichloromethane was added to a mixture of 6.93 parts pyridine and 9.35 parts phosgene in 210 parts dry dichloromethane at 25° to 30° C. The ratio of equivalents of pyridine base/COOH acid group was 1.02. After carrying out the reaction and esterifying the resulting diacid chloride by the procedure as described in Example 1, there was obtained a 94.2% yield of theory of dimethyl terephthalate corresponding to a 94.2% yield of terephthaloyl chloride formed initially in the reaction.
