从除去无机杂质和有机杂质两方面研究了得到高品位叁季戊四醇的方法 ,使叁季戊四醇产品中的单季戊四醇、双季戊四醇及灰份含量均得到显著的下降 ,其中单季从 7%降至 3%以下 ,双季从18.5 %降至 11% ,灰份从 0 .95 %降至 0 .5 %以下。将此工艺应用于工业生产 ,取得了满意的效果。
From the removal of inorganic impurities and organic impurities both high-yield three-pentaerythritol obtained by the method that the three pentaerythritol pentaerythritol products, dipentaerythritol and ash content were significantly decreased, including a single season from 7% to 3% In the following, the double season dropped from 18.5% to 11% and the ash decreased from 0.95% to 0.5%. The process used in industrial production, and achieved satisfactory results.
