摘要
以苯乙烯为参照物 ,采用气相色谱跟踪肉桂醛与苯乙烯、茴脑与苯乙烯以及肉桂醛、苯乙烯和茴脑3种化合物的混合物的臭氧化竞争性反应 ,得出此 3种化合物的反应活性由大到小的顺序为茴脑、苯乙烯、肉桂醛 ;利用膜模型理论进一步求算出肉桂醛、茴脑与参照物苯乙烯的反应速率常数比为 0 .0 5 5和 2 5 .6 ,相应的反应速率常数分别为 72 0L·mol-1·s-1和 3.33× 10
The competitive reactions of anethole,styrene and cinnamaldehyde with ozone were studied by gas chromatograph,and the reactivity sequence of the three compounds is anethole>styrene>cinnamaldehyde.The ratios of the rate constants of cinnamaldehyde and anethole to styrene were calculated according to the film theory to be 0.055 and 25.6,respectively.The corresponding rate constants of the two former compounds are 720?L·mol -1 ·s -1 and 3.33×10 5?L·mol -1 ·s -1 ,respectively.
