摘　　要：季戊四醇合成一般采用结晶法,合成反应液中往往有二季戊四醇副产物生成。本文用综合法研究季戊四醇和二季戊四醇在水中的相平衡,绘制了其饱和曲线与过饱和曲线,为在水溶液中分离提纯季戊四醇提供热力学参考依据。Synthesis of pentaerythritol used crystallization method in commonly , with by-products of dipentaerythrltol in reaction solution. This paper study on crystallization phase equilibrium of the pentaerythritol and dipentaerythritol in solution by synthesis method, and drawing its saturation curve and oversaturation curves. It provides thermodynamic reference for Separation purification of pentaerythritol in solution.

关 键 词：季戊四醇 二季戊四醇 结晶 相平衡
