Nine hetero diacetals and diketals of pentaerythritol were then synthesized by the condensation reactions of such monoacetals and monoketals with other aldehydes.

在微波辐射下,以活性炭负载磷钨酸为催化剂,N,N-二甲基甲酰胺为溶剂,将季戊四醇与醛(酮)缩合得到季戊四醇单缩醛(酮),然后再与另一种醛缩合合成了9种季戊四醇杂二缩醛(酮)。

A novel route was employed to synthesize 8-phthalimido-3,6-dioxaoctan-1-ol(3) from triethylene glycol.

以二缩三乙二醇为原料,提出了8-氨基-3,6-二氧杂辛酸(5)的新合成路线。

In this paper,the liquid s behavior in microwave irradiation and the microwave-absorbing principle are researched,and then,triethylene glycol,whose dielectric constant is great,is chosen as the quick testing s“microwave-absorbing reagent”by experiment.

对液体在微波场中的行为及其吸波原理进行了分析研究,并通过实验论证,最后选定了介电常数大的二缩三乙二醇为该快速检测试验的“微波吸收剂”。
