Abstract:
The disclosure provides a method for synthesizing paraphthaloyl chloride through terephthalic acid chlorination in a reaction mode of a microchannel continuous flow. Compared with an existing technology, this method has characteristics of accurate control of reaction conditions, high phosgene/triphosgene utilization ratio, low catalyst dosage, high TPA conversion ratio within few tens of seconds of reaction time, high TPC yield and the like.
