基于水自由基阳离子区分己烯醇碳碳双键位置的质谱研究
Mass Spectrometry Study on Distinguishing the Position of Hexenol Carbon-Carbon Double Bond Based on Water Radical Cation
摘要
Abstract
Different double bond positional isomers of hexenol have different biological activities.Rapid and accurate identification of their carbon-carbon double bond positional isomers helps to bet-ter understand their structure and biological functions.In this study,a method based on water radi-cal cations to distinguish the position isomers of the carbon-carbon double bond of hexenol was estab-lished.The specific strategy is:first,a large number of water radical cations were prepared by low-energy corona discharge technology,and then the hexenol molecule was introduced to react with the water radical cation to form the epoxidation product m/z[M+O]+·,and then the obtained epoxidation product was subjected to collision induction analysis to form a series of characteristic fragment ions m/z 60,m/z 74,m/z 88,locate the double bond,thereby distinguishing the position of different car-bon-carbon double bonds.The advantages of this method include rapid reaction,rapid and accurate mass spectrometry analysis.The experimental device is simple,without reaction pretreatment,and the experiment is simple.In addition,the reaction process does not require additional organic sol-vents and is environmentally friendly.关键词
