| Abstract: | Supported on diatomite,tungstophosphoric acid was used to synthesize N-Phenyl-2-pyrrolidinone (NPP) by mi- crowave radiation from gamma butyrolactone and aniline.The effects of various factors on the yield of NPP were examined,including the absorbing quantity of tungstophosphoric acid,quantity of catalyst,radiation power and time as well as molar ratio of reactants.Good results were obtained for NPP synthesis and the optimum conditions are as follows:absorbing quantity of tungstophosphoric acid:17. 6%,quantity of catalyst:1.5% (mass fraction),microwave power:325W,time:14min,molar ratio of gamma butyrolactone to ani- line:1.0:1.25.The yield of NPP reached over 96% with 10-fold rise of reaction speed. |
