benzyl group

The material with benzyl group as the linker shows higher catalytic activity and enantioselectivity than the material with propyl group as the linker, which is mainly due to the spacial rigidity and electron-withdrawing ability of the benzyl group.

研究表明以苄基作为环己二胺联结链的材料的催化活性和光学选择性高于相应的以丙基为联结链所得的材料，这主要归因于苄基的空间刚性和较强的吸电子性质。

The optimal conditions were found to be the molar ratio of benzyl chloride to OH group in bamboo 3, reaction temperature 80 ℃, and reaction time 2 h. It was found that the crystalline structure of the native ball-milled bamboo was damaged after benzylation modification.

适宜条件为：氯化苄对竹粉羟基的摩尔比3，反应温度80℃，时间2h。原本球磨竹粉在苄基化改性后结晶结构发生了破坏。

The protecting benzyl group was removed subsequently by catalytic hydrogenation to give poly ( 5-hydroxymethyl-1,4-dioxan-2-one)( PHDON) with pendant hydroxyl groups. The polymers obtained were characterized by FTIR, 1H NMR, 13C NMR and GPC.

通过催化氢化去除苄基保护基得到聚（5-羟甲基-1,4-二氧六环-2-酮）（PHDON），并用FTIR、1H NMR、13c NMR和GPC等方法对聚合物进行了表征。
