Brief Introduction
Bisphenol A diallyl ether is an important intermediate in organic synthesis, which is mainly used as crosslinking agent of epoxy resin. At present, most of the methods to synthesize bisphenol A diallyl ether are to add bisphenol A and base into the solvent to form bisphenol a salt, and then add allyl halide to etherify the product. This requires the use of additional solvents. The recovery and treatment of solvents not only increases the cost, but also most of the solvents used are harmful to the environment. The prior art uses ethanol as the solvent and bisphenol A, sodium hydroxide and chloropropene as raw materials to synthesize bisphenol A diallyl ether. This method uses ethanol as solvent. Although it is relatively environmentally friendly, it is difficult to reuse ethanol due to the production of water in the reaction, and excess chloropropene will react with ethanol to produce chloropropene ether. The product synthesized by this method has deep color and needs to be washed with toluene and adsorbed with activated carbon to obtain qualified products, which virtually increases the use of solvent. In the prior art, toluene and diallyl ether are used as solvents to react allyl alcohol with bisphenol A under catalyst conditions to obtain bisphenol A diallyl ether. This method will produce many by-products and the yield is very low.
