摘要
总结和归属了α－呋喃甲酸酯、α－呋喃甲醇酯、α－呋喃丙烯酸酯以及α－呋喃环在电子电离质谱（ＥＩＭＳ）中的主要裂解方式和特征，给出各化合物主要碎片离子的来源和结构。上述３类不同α－呋喃酯在ＥＩＭＳ中的基峰离子分别为９５、８１和１２１。α－呋喃离子是３类α－呋喃酯的共同碎片离子，由其裂解产生的２９。
Notable features of MS fragmentation for α _ furoic esters, α _ furancarbinol esters, α _ furanacrylic esters and α _ furan ring are summarized. The sources and chemical structures of the main fragments for α _ furan esters are interpreted. For the above three different classes of α _ furan esters under electron impact ionization, the base peaks at m/z are 95, 81 and 121. That is to say, each class yields a common base peak. The α _ furan ion is generated in cases of all three classes of α _ furan esters, and hence is a common fragment ion at m/z 67. Further fragmentation of α _ furan ion leads to the formation of other common fragment ions at m/z 41, 38 and 29.
