| titleOfInvention | The preparation method of extra high-molecular polythene catalyst |
| abstract | The present invention relates to a kind of preparation method of extra high-molecular polythene catalyst, belong to catalyst preparation technical field.This preparation method, comprises Primary Catalysts and promotor, and the preparation of Primary Catalysts comprises the steps, and adds aromatic compounds in following arbitrary step: (1) halogenated magnesium compound and varsol react; (2) add alcohol, form magnesium alkoxide compound with magnesium halide; (3) haloalkyl aluminium is added and magnesium alkoxide compound forms a kind of intermediate product; (4) ultrasonication is carried out to gained intermediate product; (5) add titanium compound, carry out carrying titanium reaction; (6) leave standstill, solid particulate washing, drying are obtained.The method is by adding aromatic compounds and being aided with intensified by ultrasonic wave technology, thus significantly can improve catalyst activity, gained catalyst reaction kinetics is steady, is easy to polymerization technique and controls, adopt the polymerisate of this catalyzer gained to have the feature of high molecular, low bulk density. |
