Abstract:A new solvent-free method for synthesizing phenol chloroformate via catalytic reaction of molten phenol with phosgene was discussed. The influences of different catalysts,catalyst dosage,reaction temperature and time on the reaction were investigated. The average yield was 88.33%,and the product content was >98% under optimized conditions. This method has the characters of easy work-up,no acid-binding agent and solvent,no wastewater and low costs,which is suitable for industrial production.
