Examples
- A process for preparing m - dichlorobenzene by atmospheric selective transfer reaction of p - dichlorobenzene in the presence of alcl3 and h2o is described . effect of selectivity of the reaction is discussed . the best technological conditions are determined
阐述了常压下对二氯苯在催化剂无水三氯化铝及助催化剂水的存在下发生转位反应，高选择地制取间二氯苯的工艺过程；讨论了影响产物选择性的有关因素，确定出适宜的工艺条件。 - The catalytic activity of ( hmbp ) 2ticl2was lower than - diketonate titanium catalysts . the catalytic activity of dinuclear - diketonate titanium catalysts was comparative to mononuclear ones . however , the dinuclear - diketonate titanium catalyst showed the synergism effect , for example , the lower catalyst concentration and the molar ratio of al to ti , the activity reached the maximum value at 80 , the melting temperature of polymer was enhanced
2 -羟基苯酮钛[ ( hmbp ) _ 2ticl _ 2 ]的催化活性低于-二酮钛类催化剂；双核催化剂在催化活性方面与对应单核催化剂相差不多，但在聚合规律上表现出与单核催化剂不同的双核协同作用，如聚合所需的催化剂浓度、助催化剂甲基铝氧烷mao量降低，活性在80时出现极值，熔点提高等，而且双核催化剂是单活性中心催化剂。
