n.脫烴基作用

The EB dealkylation reaction is not equilibium limited, allowing for up to 70 wt0% or greater EB convertion per pass. 而EB脫烷基反應(yīng)不受平衡限制，EB單程轉(zhuǎn)化率可高達(dá)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. 當(dāng)烷基苯取代基碳原子數(shù)在3以上時，烷基苯裂化反應(yīng)性能隨著烷基側(cè)鏈碳原子數(shù)的增加而增加，烷基側(cè)鏈含有叔碳原子則更易裂化，苯的生成主要來自脫烷基反應(yīng)；

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. 結(jié)果表明氟樂靈在土壤中的降解主要形成脫烷基和硝基還原產(chǎn)物,降解物的種類和數(shù)量的分布均受土壤條件控制;

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. 結(jié)果表明，異丙苯裂化中的主要反應(yīng)為脫烷基反應(yīng)和側(cè)鏈質(zhì)子化裂化反應(yīng)，苯主要來自異丙苯的脫烷基反應(yīng)；
