Chloromethylation Research of LX-1180 Macroporous Adsorption Resin in Ultrasonic Environment

This work performed the chloromethylation study of LX1180 in an ultrasonic environment, and presented a novel method to realize high chloromethylation degree for high crosslinking MARs. During this process, Monochloromethyl ether and anhydrous zinc chloride was adopted as chloromethylation reagent and catalyst respectively, the influences of conditions on the chloromethylation degree were investigated and optimized systemically. The sample prepared under the optimization conditions possessed the chloromethylation degree of 2.87 mmol/g.
