Abstract

The embodiment of the invention discloses a deactivator for polypropylene production and relates to the technical field of olefin polymerization. The deactivator comprises glycerin fatty acid ester and polyglycerol fatty acid ester at the molar ratio of (0.01-0.99):(0.01-0.99). The deactivator can be applied to propylene polymerization activity control and polypropylene power discharging deactivation, and successfully overcomes the defect that the amine deactivators are only suitable for part of devices (the amine deactivators have extremely high de-activity, are only applied to ring tube polymerization discharging and cannot be applied to other process because a feeding port of the position is not designed). The deactivator can be added into a reaction device, also can be used at a discharging port, is suitable for all the existing polypropylene processes, and has the advantages of controllable deactivation efficiency, moderate adding amount, high anti-static property and high anti-caking property. The deactivator belongs to alcohol deactivators, has no any odor and color, is safe and environmentally-friendly, and is suitable for producing high-quality polypropylene products.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of olefin polymerization, in particular to an activator for polypropylene production. Background technique [0002] Propylene needs to use a catalyst in the polymerization process. The propylene polymerization catalyst system is mainly Ziegler-Natta system. If the residual active agent in the feeding process is not killed in time, it will further react with propylene gas to form oligomers. These oligomers not only consume the raw materials for polypropylene production, but also affect the quality of polypropylene, and at the same time cause polypropylene powder Problems such as adhesion and agglomeration of materials will cause difficulties in pipeline transportation and easy material blockage, which will affect the continuous operation of polypropylene. [0003] At present, in some processes, activators are added at the powder outlet to solve the problem of catalyst activity resid...
