| Abstract: | 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. |
