4-乙基-2,6,7-三氧杂-1-磷杂双环[2,2,2]辛烷(简称BTMP,下同)是涤纶阻燃剂的重要中间体,也是其它高分子材料如聚氨酯、聚酰胺、聚烯烃的阻燃活性单体,有关它的分析可用氧化法测含磷量的化学分析法,但在阻燃剂物系分析中,尚需与其他有机膦酯化合物分离,因此用氧化法测磷含量的化学分析法不但操作烦琐、费时,且不能达到分离各个测定的目的,而气相色谱法能较好满足要求,且操作方便,定量准确。但BTMP是一种具有较高活性的刚性双环有机膦化合物,对于这种特殊结构因而具有特殊性质的化合物的气相色谱分析未见有文献报道。本文研究了它的气相色谱分析条件。
4-Ethyl-2,6,7-trioxa-1-phosphabicyclo [2,2,2] octane (BTMP, the same below) is an important intermediate of polyester flame retardant, Materials such as polyurethanes, polyamides, polyolefins, flame retardant active monomer, its analysis can be measured by oxidation of phosphorus content of chemical analysis, but in the flame retardant system analysis, still need to be with other organic phosphine ester compounds Therefore, the chemical analysis method of phosphorus content by oxidation method is not only tedious and time-consuming, but also can not achieve the purpose of separation of each determination, and the gas chromatography can better meet the requirements, and the operation is convenient and quantitatively accurate. However, BTMP is a kind of rigid bi-cyclic organophosphorus compound with high activity. Gas chromatographic analysis of compounds with special properties for this special structure has not been reported in the literature. This article studies its gas chromatographic conditions.
