摘要
对聚乙二醇的应用及生产情况作了简介 ,介绍了由环氧乙烷与水 ,或乙二醇经分步反应合成聚乙二醇的工艺 ,重点介绍了以甲醛为原料合成乙二醇的四种方法。认为以价廉的C1原料生产聚乙二醇 ,具有潜在的市场前景。
The application and production status of polyethylene glycol was briefly introduced. The synthesis processes for producing polyethylene glycol by oxirane and water, or ethandiol were related.Four methods for synthesizing ethandiol by methyl aldehyde as material were described emphatically.It was thought that producing polyethylene glycol by C 1 compounds as cheap materials has potential market prospect.
