Industrial continuous production equipment for polycarbonate polyether polyol

Abstract

The invention provides industrial continuous production equipment for polycarbonate polyether polyol. The industrial continuous production equipment comprises a CO2 adding device, an epoxide adding device, a chain transfer agent adding device, a catalyst adding device, a premixing kettle and a straight-tube reactor; the premixing kettle is used for mixing epoxide, a chain transfer agent, a catalyst and low-pressure CO2 to form a primary mixture, and enabling the primary mixture to be in a to-be-reacted state; the straight-tube reactor is used for mixing the primary mixture and high-pressure CO2 to form a secondary mixture and enabling the secondary mixture to be in a synthetic reaction state; a straight-tube accommodating cavity is formed in the straight-tube reactor, a reaction mixing device is arranged in the straight-tube accommodating cavity, and the bottom of the straight-tube reactor is communicated with the premixing kettle and the CO2 adding device; a feeding pump used for pumping the primary mixture from the bottom of the straight-tube reactor is further connected between the premixing kettle and the straight-tube reactor, and the straight-tube reactor is vertically or obliquely arranged. According to the industrial continuous production equipment, the amplification effect can be avoided or relieved, and the reaction time is shortened.

Description

technical field [0001] The invention relates to the production technology of polycarbonate polyether polyol, in particular to an industrial continuous production equipment of polycarbonate polyether polyol, especially an industrial continuous production equipment without amplification effect. Background technique [0002] Since the industrial revolution, the extensive use of fossil energy has caused carbon dioxide emissions to increase year by year, and environmental pollution has become more and more serious. As a rapidly developing China, it is inseparable from the extensive use of fossil energy, and the situation of emission reduction is not optimistic. Plants use photosynthesis to absorb carbon dioxide and release oxygen, which is an environmentally friendly way, but the effect is slow. Humans can use chemical reactions to quickly achieve large amounts of consumption. [0003] Polycarbonate polyether polyols are formed by polymerizing carbon dioxide and epoxy compounds,...
