| Abstract: | We use L-aspartic acid(L-ASP) as the raw material,phosphoric acid as a catalyst,propylene carbonate as the solvent,to produce polyaspartic acid(PASP) with microwave radiation polymerization in microwave reactor.This study use orthogonal experimental to analyze the influence of reaction conditions of poly-aspartic acid synthesis by microwave radiation on yield rate and the molecular weight.The results show that the best conditions for synthesis of polyaspartic acid are: 5% of catalyst,455W of microwave power... |
