碩士 === 義守大學 === 生物技術與化學工程研究所 === 100 === Diphenyl carbonate (diphenyl carbonate, DPC) is an important chemical intermediate, with low toxicity and non-polluting. DPC can undergo a wide range of reactions, such as halogenation, nitration, hydrolysis and aminolysis reactions, to form many organic compounds or synthetic polymers. Recently, it was found that, in polycarbonate production, DPC can be used, instead of phosgene, to react with bisphenol A by melt transesterification to produce polycarbonates. This makes DPC become an economic and environmental potential product worth in industrial applications. Therefore, for the demand of DPC process development, we select three major ingredients in DPC process, methyl acetate, dimethyl carbonate and phenyl acetate, to study the binary vapor-liquid equilibrium system. All VLE experiments in this study have passed the vapor-liquid equilibrium thermodynamic consistency verification. In addition to VLE, the vapor pressure of methyl acetate, dimethyl carbonate and phenyl acetate are measured. Their NRTL parameters for the VLE information are reported as well.
