环氧乙烷-四氢呋喃共聚醚与硝酸酯的相溶性

The Miscibility of Ethylene Oxide—Tetrahydrofuran Copolyether in Nitrates

研究了离子增溶剂（ＩＳＲ）对Ｐ（Ｅ－ＣＯ－Ｔ）／ＮＧ体系相溶性的影响，通过ＲＰ－ＨＰＬＣ测定了互溶相中ＮＧ含量。同时考察了在ＩＳＲ存在下，Ｐ（Ｅ－ＣＯ－Ｔ）与硝酸酯体系在室温及低温下互溶限度。通过ＦＴＩＲ分析表明，在ＩＳＲ存在下，Ｐ（Ｅ－ＣＯ－Ｔ）与硝酸酯体系由于氢键作用使其相溶性明显增加。

The effects of quantities of ion solubilizing reagent(ISR)on miscibility of THF and ethylene oxide co polyether P(E-CO-T) with nitroglycerin(NG).Nitroglycerin content in miscible phase was determined byrevesed phase high performance Liquid Chromatography.The miscibility Limits of P(E-CO-T)/NG,P(E-CO-T)/NG+BTTN sytems at ambient and negative temperatures in the presence of ISR were investigated.The solubilization of the systems was explored by FTIR. The results of this research show that the addition of ISR obviously increase the miscibility between P(E-O-T)and nitrates.
