Preparation of environmentally friendly anion exchange resin
Abstract:The conditions of amination reaction in the preparation of environmentally friendly anion exchange resin have been studied. In the preparation of environmentally friendly anion exchange resin, the PS-DVB copolymers were chloromethylated with long chain alkylhalomethyl ethers without carcinogenic toxictiy, then the products were aminated and the final products’ structrue were identified by FT-IR. Various factors of amination reaction were studied to obtain the optimal reaction conditions. The results show that the optimal ino-exchange capacity（IEC） reached 2.76mmol/g, water content is 12%~36% and amination degree is 0.07~0.65 ,the light yellow transparent environment-friendly anion exchange resin were obtained.
