摘要
本文用自旋捕捉技术与ESR相结合方法,系统研究了放电管直径及水含量对低压下脂肪醚气相微波放电分解产生自由基的影响。表明:随着放电管直径减小,放电时碳化现象加重,H·原子寿命变短;含水量加大,碳化剧烈。并根据其放电机理,对以上现象发生的原因进行一定的探讨。
By means of the spin trapping -ESR technique, the influence of the tube diameters and moisture content in the sample on the radicals produced in the microwave discharge of fatty ether at low pressure has been studied systematically. The results show that: the smaller the diameter of the tube, the faster the formative speed of carbon black, as well as the shorter the lifetime of H atom. With the increase of moisture content, the extent of carbonization becomes more serious. According to the mechanism of discharge, the reasons of the carbonization are discussed.
