产品描述

二甘醇二甲醚(二甘醇二甲醚),一种亲水性醚,是一种电子给体溶剂。已对其毒性进行了评估。研究了二甘醇二甲醚与三氟甲磺酸锂络合对构象的影响。据报道,它可以增强KF-MeOH-Al2O3(氟化钾-甲醇-氧化铝)试剂用5,8-二羟基-2,3-二氯-1,4-萘醌中的甲氧基取代卤素的能力。二甘醇二甲醚可用作溶剂形成五磷环戊二烯酸钠溶液。

General description

Diethylene glycol dimethyl ether (diglyme), a hydrophilic ether,[1] is an electron-donor solvent.[2] Its toxicity has been assessed.[3] The effect of complexation of diglyme with lithium trifluoromethanesulfonate on the conformation has been investigated.[4] It is reported to enhance the ability of KF-MeOH-Al2O3 (potassium fluoride-methanol-alumina) reagent to replace halogen with methoxy groups in 5,8-dihydroxy-2,3-dichloro-1,4-naphthoquinones.[2]

Application

Diethylene glycol dimethyl ether may be used as a solvent to form a solution of sodium pentaphosphacyclopentadienide.[5]
