稳定剂对四溴乙烷稳定性的影响

Effect of Stabilizer on Stability of Tetrabromoethan

采用色谱质谱联用仪分析了四溴乙烷产品的主要组分,研究了乙二醇二缩水甘油醚和复合稳定剂对四溴乙烷稳定性的影响。研究表明,乙二醇二缩水甘油醚和复合稳定剂可以显著提高四溴乙烷的稳定性,延长储存时间。复合稳定剂的稳定效果好于乙二醇二缩水甘油醚。分析了稳定剂提高四溴乙烷稳定性的作用机理。

Components in tetrabromoethan product were identified by using GC-MS,and effect of ethylene glycol diglycidyl ether and composite stabilizer on stability of tetrabromoethan was also studied.The results show that stability of tetrabromoethan is obviously improved and its storage time is increased by using ethylene glycol diglycidyl ether and composite stabilizer.Effect of composite stabilizer on stability of tetrabromoethan is better than ethylene glycol diglycidyl ether.At last,mechanism of improving stability of tetrabromoethan was also studied.
