反応手順
A mixture of 150 g of dimethyl terephthalate and 7 g of triphenylphosphine oxide was gassed with phosgene as in Example 1. After 5 hours, the reaction mixture contained only 1.3% of dimethyl terephthalate and 1.3% of methyl terephthalate chloride. After 6-7 hours, the conversion was complete and terephthalic acid dichloride was obtained (>99% pure).
