| titleOfInvention | A kind of ethylene trimer of high selectivity, four poly- catalyst systems and its application method |
| abstract | The present invention provides a kind of ethylene trimer of high selectivity, four poly- catalyst systems and its application method, and the catalyst system includes three parts：（1）A kind of chromium compound；（2）A kind of part, its general structure is：(Ph 2 )P‑N(R 1 )‑P(Ph 2 ), wherein R 1 It is phenyl, the alkyl or cycloalkyl of synthesis；（3）A kind of activator or co-catalyst.The catalyst system is improved to original PNP chromium-based catalysts, improves the common selectivity of 1 hexene and 1 octene, reduces wax-like product, and maintain activity higher. |
