The results showed that the first canonical correlation coefficient between aldehydes, ketones, esters and the total quantity of each kind of ingredient and smoking quality achieved 5 % or 1 % remarkable level. And their correlation depended mainly in the correlation between phenylacetaldehyde, furfural, megastigmatrienone-1, megastigmatrienone-3, geranylacetone,β-damascenone, keto-isophorone, dihydroactinidiolide and smoking quality.
结果表明：醛类成分、酮类成分、酯类成分与香气质、香气量的第一典型相关系数达到5%或1%显著水平，各类成分总量与香气质、香气量的第一典型相关系数达到1%极显著水平，其相关关系主要表现在苯乙醛、糠醛、巨豆三烯酮1、巨豆三烯酮3、香叶基丙酮、β-大马酮、氧化异佛尔酮、二氢猕猴桃内酯等成分与香气质、香气量的相关上。

Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.
同时结合Ti-ZSM-5催化选择性氧化苯乙烯反应的产物分布结果，提出苯乙烯环氧化反应可能是通过金属有机环机理进行；Ti-ZSM-5同时具有催化环氧化和酸催化两种功能，其骨架钛可催化苯乙烯环氧化生成环氧苯乙烷，而骨架钛和骨架铝等可提供Lewis酸位使环氧苯乙烷迅速发生重排生成苯乙醛从而使其成为反应的主要产物，同时还可发生加成以及碳碳键的裂解等副反应：Ti-ZSM-5也提供Bronsted酸位，它也是生成加成产物的活性中心。

Methods Phenylacetaldehyde was prepared from benzimidazolium salt and benzyl chloride by the addition-hydrolysis reaction of benzimidazolium salt with Grignard reagent.
方法以苯并咪唑盐和苄基氯为原料，利用苯并咪唑盐与Grignard试剂的加成-水解反应合成苯乙醛。

The selectivity of phenylacetaldehyde is increased when Br〓nsted acidity is getting stronger. The selectivity of benzaldehyde can be increased by increasing the amount of extraframework titanium species.
分子筛的B酸中心强度对产物分布有着显著的影响，B酸越强，苯乙醛的选择性越高，B酸位是催化环氧苯乙烷定向重排生成苯乙醛的催化活性中心；非骨架钛物种的增加有利于苯甲醛的生成。
