本文用CW和TEA CO2激光器研究了F12(CF2Cl2)、F114(CF2ClCF2Cl)和F22(CF2HCl)等碳卤化合物的激光诱导解离反应, 实验发现, 在激光作用下, 这些化合物的解离方式不仅与化合物的性质有关, 还与激光的能量密度密切相关; F22的激光解离为一级反应,并存在“瓶颈效应".

关键词: 卤化物, 分解反应, 通道, 激光化学, 氟氯碳

The laser induced decomposition of CF2Cl2, CF2ClCF2Cl, and CHF2Cl was studied by means of CW and TEA CO2 laser resp. The main aspects studied were the channel competitive processes and the relations between the reaction channels and laser energy fluence. The results show that the decomposition channels depend on both laser energy fluences and nature of compounds The laser decomposition of F22 is first order reaction and there is bottle-neck effect in F22 laser induced decomposition
