目的研究一种新型系列杀虫剂（含呋喃环新型双酰基脲类几丁质抑制剂）的热稳定性和热降解机理。方法用裂解气相色谱法分析不同温度下的裂解产物含量，绘制裂解百分数。裂解温度曲线；用裂解气相色谱／质谱法分析鉴定裂解产物。结果与结论新型系列杀虫剂与对照药剂苏脲１号相比，热稳定性较好，受热时主要在双酰基脲的Ｃ－Ｎ键处发生断裂。
Objective To study the thermal stability and thermal degradation mechanism of a new series of pesticides (chitin inhibitors containing furan ring). Methods Pyrolysis products were analyzed by pyrolysis gas chromatography at different temperatures, and the percentage of lysis was plotted. Pyrolysis temperature profile; cleavage products were identified by pyrolysis gas chromatography / mass spectrometry analysis. RESULTS AND CONCLUSION The new series of insecticides showed better thermal stability than that of the control agent Su urea 1, which was mainly broken at the C-N bond of the bisacylurea when heated.
