The effect of type of functional monomers,as well as degree of cross-linking on the regioselectivity of nitration reaction,is studied.
成功地将分子印迹聚合物用于催化NO2硝化反应,探讨合成分子印迹聚合物所用的功能单体种类、交联度等对甲苯的NO2硝化反应位置选择性的影响。
In this system good regioselectivity can be achieved mainly because of the existence of a porous support and the low dielectric constant of the reaction media.
一定条件下该硝化剂具有较好的反应位置选择性，这一是由于反应介质低的介电常数，二是多孔载体也具有明显的作用。
In the two-phase nitration of phenol in the persence of β-CD,the regioselectivity of the reaction could be improved markedly,factors such as the polarity of the organic solvents,the amount of sodium nitrate used and reaction temperature have been investigated.
β－ＣＤ存在下对苯酚进行两相硝化反应，可以明显改善反应的位置选择性。
