三-[1-(2-甲基-乙撑亚胺基]氧化膦(tris-[1-(2-Methyl)aziridinyl]phosphine oxide)以下简称MAPO,是一种广泛使用的交联剂,其中所含水份对于交联剂的使用影响很大,必须控制。通常的卡尔费休水份测定法,由于存在干扰,终点不明显,不能应用。1968年曾有报导在3700cm~(-1)—3100cm~(-1)红外区域,以积分强度法进行MAPO中水份的测定,但此法较为复杂,且样品中存在的杂质对测定有干扰。本实验应用四氢呋喃为稀释剂,在Unicam SP700型分光光度计上近
Tris- [1- (2-Methyl) aziridinyl] phosphine oxide, hereinafter abbreviated as MAPO, is a widely used crosslinking agent in which The moisture content of the cross-linking agent for the use of a great influence, you must control the usual Karl Fischer moisture determination, because of interference, the end point is not obvious, can not be applied .1968 years have been reported at 3700cm -1 -3100cm ~ (-1) infrared region, the determination of the water content in MAPO by the integral intensity method, but this method is more complicated, and the impurities in the sample interfere with the determination.In this experiment, tetrahydrofuran as a diluent, Unicam SP700 Type spectrophotometer on the near
