AI Technical Summary
Existing technologies for the synthesis of p-tert-butylbenzyl chloride suffer from problems such as low catalytic efficiency, long reaction cycles, unstable product yields, and poor environmental safety.
Using boron trifluoride acetonitrile complex as a catalyst, and tert-butylbenzene, paraformaldehyde, and hydrogen chloride as raw materials, p-tert-butylbenzyl chloride was synthesized under mild reaction conditions. By controlling the reaction temperature, catalyst dosage, and hydrogen chloride introduction rate, a highly efficient chloromethylation reaction was achieved.
It increases the conversion rate of tert-butylbenzene to over 90%, the product yield to over 85%, shortens the reaction time to 6-12 hours, reduces catalyst usage and waste emissions, and lowers production costs and environmental risks.
