化学电离(CI)质谱是研究气相离子反应的重要工具。在离子源中,反应离子通常与样品分子发生质子转移或电荷交换反应,使样品分子电离,达到分子量测定的目的。Weinkam和Desiderio等曾研究了气相离子的溶剂解反应。近年来人们开始注意到气相离子可以发生许多经典有机化学反应。我们用甲醇作反应气,对不同类型的一元羧酸
Chemical ionization (CI) mass spectrometry is an important tool for studying the gas phase ion reaction. In the ion source, the reaction ions usually proton transfer or charge exchange reaction with the sample molecules, ionization of the sample molecules to achieve the purpose of molecular weight determination. Weinkam and Desiderio et al. Studied the solvolysis of gas phase ions. In recent years, people began to notice that many classical organic reactions can occur in gas phase ions. We use methanol as the reaction gas, for different types of monocarboxylic acids
