利用激光闪光光解技术进行了有氧和无氧条件下氯化三苯基锡与亚硝酸水溶液的紫外光解反应研究.结果表明,·OH和三苯基锡阳离子(SnPh+3)反应生成了瞬态粒子SnPh+3-OHadduct,其二级生成速率常数为(7.9±1.2)×109L·mol-1·s-1.在N2饱和时,SnPh+3-OHadduct以单分子反应方式衰减,衰减速率常数为(1.15±0.15)×105s-1;在O2饱和时,表观一级衰减常数增加为(1.87±0.25)×105s-1,这是由于SnPh+3-OHadduct能够与O2发生作用生成SnPh+3-OHO2,其二级反应速率常数为(6.0±2.9)×107L·mol-1·s-1.
The photolysis of triphenyltin chloride with aqueous solution of nitrous acid under aerobic and anaerobic conditions was studied by laser flash photolysis. The results showed that the reaction of · OH with triphenyltin tin (SnPh + 3) The second order formation rate constant of SnPh + 3-OHadduct was (7.9 ± 1.2) × 109L · mol-1 · s-1 for SnPh + 3-OHadduct. At N2 saturation, SnPh + 3-OHadduct attenuated by single molecule reaction, The decay rate constant was (1.15 ± 0.15) × 105s-1. At the time of O2 saturation, the apparent first order decay constant increased by (1.87 ± 0.25) × 105s-1, which was attributed to the interaction of SnPh + 3-OHadduct with O2 The second order reaction rate constant is (6.0 ± 2.9) × 107L · mol-1 · s-1 for SnPh + 3-OHO2.
