Industrial manufacturing method of cheegre Natta catalyst

摘要

The present invention relates toAbout the technology of catalyst manufacturingDisclosed is a method for producing a cheetah Natta catalystIn the presence of an inert solventMagnesium halidesAlcohols and electron donors were first catalyzed to form a magnesium halide alcohol adductFirst cooling processThe second step of cooling the titanium halide isTitanium halides after coolingAfter the cooling, the products are contained and the electron donors are subjected to the second contact reaction with the products containing the additive.Filter the second contact reaction productObtaining the cheetah Natta catalyst andCheetah Nitta catalyst and the third contact reaction of titanium halides after heating.The method has advantages such as short cycle and high efficiency, and is suitable for industrial production.
