n.脱烃基作用
The EB dealkylation reaction is not equilibium limited, allowing for up to 70 wt0% or greater EB convertion per pass. 而EB脱烷基反应不受平衡限制，EB单程转化率可高达70%25（重量比）或更高。
When the number of side chain carbon is over 3, these alkylaromatics are prone to side chain cracking and benzene is mainly formed by dealkylation. 当烷基苯取代基碳原子数在3以上时，烷基苯裂化反应性能随着烷基侧链碳原子数的增加而增加，烷基侧链含有叔碳原子则更易裂化，苯的生成主要来自脱烷基反应；
The results show that dealkyl -and nitro -reduced compounds are the main degradation products of trifluralin in soils, whose kind and amount depend on soil conditions. 结果表明氟乐灵在土壤中的降解主要形成脱烷基和硝基还原产物,降解物的种类和数量的分布均受土壤条件控制;
The results indicated that the main reactions of cumene cracking were dealkylation and protolytic cracking of alkyl side chain.Benzene was mainly formed by the dealkylation reaction. 结果表明，异丙苯裂化中的主要反应为脱烷基反应和侧链质子化裂化反应，苯主要来自异丙苯的脱烷基反应；
