酸性磷(膦)酸酯与四甲基氢氧化铵的甲醇溶液反应制得的四甲基铵盐溶液,热解转化成O-甲基化产物用气相色谱鉴定。分离与鉴定了磷酸二烷基酯、磷酸单烷基酯、烷基膦酸单烷基酯和二烷基膦酸等,并讨论了烷基碳原子数和烷基的空间效应对校正保留时间(t′_R)及保留指数(I)的影响。
The tetramethylammonium salt solution of acidic phosphorus (phosphine) acid ester and tetramethylammonium hydroxide in methanol solution was pyrolyzed and converted to O-methylated product and identified by gas chromatography. The dialkyl phosphates, monoalkyl phosphates, alkyl monoalkyl phosphonates and dialkyl phosphonic acids were isolated and identified. The effects of the alkyl carbon number and the space effect of alkyl on the retention time (t’_R) and retention index (I).
