Biodiesel is a fatty acid methyl ester obtained by esterification and transesterification of animal and vegetable oils with short-chain alcohols such as methanol, and is a renewable and clean energy source. During the production of biodiesel, glycerin, fatty acids, metal salts, traces of water and methanol are left behind. These substances can be removed by ion exchange resin to purify biodiesel and improve the efficiency of use.
Ion exchange resins can also be used as acid catalysts. Compared with power or liquid catalysts, they have the advantages of easy separation, low corrosion to equipment, low environmental pollution, and continuous production，etc . It is mainly used for the synthesis of bisphenol A, catalytic synthesis of MTBE and TAME, and can also be used for esterification, hydrolysis, alkylation, etherification ,etc.
