Synthesis of 3-chloro-2-hydroxy propyl methacrylate andion exchange resins therefrom

摘要

3-Chloro-2-hydroxy propyl methacrylate (CHPMA) was prepared using methacrylic acid and epichlorohydrin. The effect of catalyst and temperature on the rate of conversion was studied. Benzyl trimethyl ammonium chloride was found to be very effecitve as a catalyst. The chloromethyl moiety on the resultant polymer was utilized for synthesizing ion excahne resins. Polymers of CHPMA cross linked with DVB were prepared, which were ten reacted with various amines to give ion exchange resins. Effect of dioxolane as a swelling agent, along with its recovery was also studied. The ion exchange resins were characterized by their capacity, consistency in capacity, void volume and water regain.
