Pentaerythritol is a kind of organic chemical product with wide industrial application, mainly used in coating industry.In the process of producing pentaerythritol, dipentaerythritol by-products are often generated. Even in the final product of pentaerythritol, there is a certain amount of dipentaerythritol.At present, there is no perfect method for simultaneous determination of both.

A gas chromatography method for the separation and determination of pentaerythritol and dipentaerythritol was established by Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd.The relative standard deviations of pentaerythritol and dipentaerythritol were 2.4% and 4.5%, respectively.The recovery rate of addition was 96.36% and 95.78%, respectively.Methods The method was used to select the production conditions of dipentaerythritol and control the concentration of reaction solution.
