Ethylation selectivity, was affected by strength of surface acid sites, location of acid sites and pore structure.
乙基化的选择性则与催化剂的表面酸强度、酸性中心位置和孔道结构等因素有关。
The variation of this pH range was dependent on the strength of the base, the volume of the conjugated acid cation, and whether this cation can increase the surface charge of the micelles or not, etc.
这一范围的大小（宽窄）受制于碱的强弱、共轭酸阳离子的体积以及共轭酸阳离子是否能增加胶束表面的电荷等几个方面。
