Abstract

The invention provides a continuous reaction device for preparing epoxidized soybean oil. The device comprises a heating reaction kettle and a plurality of heat preservation reaction kettles; the heating reaction kettle and the heat preservation reaction kettles are arranged; the heating reaction kettle is connected with a buffer material storage tank, the buffer material storage tank is respectively connected with each heat preservation reaction kettle, meanwhile, a stirring motor and a stirring paddle are arranged on each of the heating reaction kettle and the heat preservation reaction kettles, a heating device is arranged on the heating reaction kettle, and a cooling cavity is formed in each heat preservation reaction kettle. According to the invention, full mixing of materials is ensured through stirring of the stirring paddle; meanwhile, one heating reaction kettle is connected with the plurality of heat preservation reaction kettles in parallel, so that the heating reaction kettles and the heat preservation reaction kettles with different reaction speeds are coordinated with each other, continuous and stable production of the epoxidized soybean oil is realized, the idle rateof equipment is reduced, and the production efficiency of products is greatly improved.

Description

technical field [0001] The invention relates to the technical field of preparation equipment for epoxidized soybean oil, in particular to a continuous reaction device for preparing epoxidized soybean oil. Background technique [0002] Epoxidized soybean oil is a chemical product obtained by oxidizing soybean oil. It is a light yellow viscous oily liquid at room temperature. It is a non-toxic plasticizer and stabilizer for polyvinyl chloride widely used: it is compatible with PVC The resin has good compatibility, low volatility and low migration. It has excellent thermal stability and light stability, good water resistance and oil resistance, can endow products with good mechanical strength, weather resistance and electrical properties, and is non-toxic. It is an internationally recognized chemical process additive for food packaging materials . [0003] At present, the preparation of epoxidized soybean oil in China mainly adopts a high-temperature and low-concentration hyd...
