非芳香性1，2，4－三嗪衍生物质谱研究

A Study on the Mass pectrometry of Nonaromatic 1,2,4- triazines

本文对１０种非芳香性１，２，４－三嗪衍生物的质谱裂解规律进行了研究，发现主要裂解方式是ｂ－ｅ裂解。对６－乙氧羰基－３－巯基－５－羟基－１，２，４－三嗪进行了ＥＩ－ＭＩＫＥＳ研究，发现脱掉６位取代基后容易发生ｂ－ｅ和ａ－ｃ等开环裂解方式。

The mass spectrometryoften nonaromatic1,2,4 triazines was studied.The b-efragmentation was popular.6-ethoxycarbonyl-3-thioio-5-hydroxy-1,2,4-tri-azine was studied with EI-MIKES method.b-e and a-c and other rine fragmenta-tions were found in the spedes formed from the disassociation of 6-substituent.
