Catalytic synthesis of diethyl adipate by environmentally friendly catalysts

The preparation methods of diethyl adipate catalyzed by strong acidic cation exchange resin, ammonium ferric sulfate dodecahydrate, cupric sulfate, sodium bisulfate monohydrate, solid superacid, heteropolyacid and molecular sieve were reviewed.The reaction conditions,specificity of catalysts and features of synthetic process under the action of the catalysts was expounded. It enumerated the predominaces of every catalysts reaction time,agent of getting water,on the rate of production,whether or not for the catalysts to reuse. It point out the solid catalysts that we have studied are all good catalyst for synthesis of diethyl adipate. 
