Abstract

The invention discloses a butene-1 polymerization reaction kettle and a butene-1 polymerization reaction heating method, relates to the technical field of chemical engineering, and aims at decreasing the temperature gradient of reaction materials in the radial direction of the reaction kettle and increasing the polymerization speed and the polymerization degree of polybutylene-1. The butene-1 polymerization reaction kettle comprises a reaction kettle body and a condenser; the reaction kettle body is provided with a stirring device, the heat absorption side of the condenser is communicated with a refrigerant circulating pipeline, a steam outlet of the reaction kettle body and a heat release side inlet of the condenser are connected through an air extraction pipeline, and a heat release side outlet of the condenser is connected with a reflux inlet of the reaction kettle body through a reflux pipeline; the air extraction pipeline extracts saturated steam of a butene-1 polymerization reaction system in the reaction kettle body, wherein butene monomer steam is contained in the saturated steam. The butene-1 polymerization reaction heating method is applied to the butene-1 polymerization reaction kettle. The butene-1 polymerization reaction kettle is applied to polybutylene-1 production.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a butene-1 polymerization reactor and a method for obtaining heat from butene-1 polymerization reaction. Background technique [0002] At present, polybutene-1 generally adopts the liquid phase bulk polymerization process to achieve industrial production. In the industrial production process, the polymerization reaction is carried out in the reactor, and the heat released by the butene-1 polymerization reaction system is cooled by the outside of the reactor. The refrigerant circulating in the jacket is taken out. [0003] However, due to the increase of butene-1 polymerization reaction time, the viscosity of the reaction system material in the butene-1 polymerization reaction will be higher and higher, which will increase the heat transfer and mass transfer difficulties in the reactor, resulting in the reaction of the reaction material. There is a large temperature gra...
