Abstract
A non-metalloene catalyst and its preparing process are disclosed. Said catalyst can be carried by inorganic chloride or silica gel in a simple way. It is use in conjunction with organoaluminium cocatalyst for homopolymerizing of ethene or copolymerizing of ethene and alpha-olefin.
Description
Technical field
The present invention is a kind of non-metallocene catalyst and preparation method thereof, specifically, is a kind of non-metallocene catalyst and loaded catalyst and these two kinds of Preparation of catalysts methods that contain the acetonaphthol part.
Background technology
Continuing typical is the transistion metal compound of part with cyclopentadiene and derivative thereof, be after the metallocene catalyst, the class metallocene compound that contains coordination heteroatom ligands such as aerobic, nitrogen in the another kind of conjugated system causes more and more that in the application aspect polyolefin, the especially polyethylene catalysts people pay attention to and pay close attention to.
Recently, people also make loaded catalyst as active constituent loading with above-mentioned catalyst in research on different inorganic compound carriers in research metallocene and class metallocene catalyst.As, it is active component with the metallocene that USP5869417 discloses a kind of, molecular sieve is the preparation method of the loaded catalyst of carrier, the used carrier of this patent is the macroporous structure molecular sieve with 7～15 apertures, as faujasite, SAPO-37 etc., the catalyst that load metallocene makes on above-mentioned molecular sieve carrier can be used for ethene, propylene or cinnamic polymerization.
People such as K.Soga are at J.Polym.Sci., Polym.Chem.Ed.35, the polymerization that the cyclopentadiene titanium trichloride is carried on the catalyst that makes on the magnesium chloride support discussed in the article that 291-311 delivers, this catalyst and triisobutyl aluminum cocatalyst are used and can prepare polypropylene, and have high polymerization activity.
CN1461756A discloses a kind of non-metallocene catalyst and loaded catalyst thereof; the part of this catalyst is the acyl-naphthaline phenolic compounds; the alkali metal salt of catalyst employing acyl group naphthols and transition metal halide react at a lower temperature and make; its loaded catalyst is that described Nonmetallocene active component solids is dispersed in the solvent, makes with the carrier reaction again.The polymerization activity of catalyst still remains to be improved, and Preparation of Catalyst cost height, complicated operation.
Summary of the invention
The purpose of this invention is to provide a kind of non-metallocene catalyst and preparation method thereof, this catalyst method for making is simple, is used for ethylene polymerization and has higher activity.
Non-metallocene catalyst provided by the invention, its general expression is: M (L)

Two kinds of parts are arranged in the non-metallocene catalyst provided by the invention; a kind of part removes the hydrogen proton by the acyl-naphthaline amphyl and forms; by beta-diketon structure and the coordination of transition metal formation bidentate wherein; another kind removes the hydrogen proton by phenol derivatives or alcohol and forms, and forms coordination by oxygen atom and transition metal.This Nonmetallocene compound has high polymerization activity than the transistion metal compound with single acyl-naphthaline amphyl part.In the described loaded catalyst, the hydroxyl in Nonmetallocene compound and the carrier interacts, and produces organically combination, thereby active component is distributed on the carrier more equably.Described method for preparing catalyst is simple, the reaction condition gentleness, and the salt that end reaction generates is magnesium chloride, thereby can simplify the preparation process of loaded catalyst.
The specific embodiment
The present invention is earlier with phenol derivatives or alcohol compound and alkyl aluminum reaction described phenol of formation or pure aluminium salt; make itself and dialkyl magnesium reaction generate aluminium-magnesium complex again; again with this complex and the reaction of acyl-naphthaline amphyl; and then generate the Nonmetallocene compound with the halide reaction of transition metal; it is catalyst; in the process that generates catalyst, be attended by the generation of magnesium chloride; thereby when the preparation loaded catalyst; can filter; directly will contain the reaction product of Nonmetallocene compound and the carrier haptoreaction of using alcohol to handle that adds, can make loaded catalyst.
Catalyst general formula of the present invention is M (L)
