Preparation method of novel epoxidized soybean oil and control system thereof

Abstract

The invention belongs to the technical field of food production and processing, and discloses a preparation method of novel epoxidized soybean oil and a control system thereof. The preparation methodcomprises the following steps: selecting soybean oil, detecting the selected soybean oil by utilizing a refrigerating and heating device, treating the soybean oil which is detected to be qualified andserves as a main material, adding a catalyst and an auxiliary agent into the treated soybean oil, mixing, and putting the mixture into a reaction kettle; sealing the reaction kettle, and keeping thetemperature of the mixture; introducing oxygen into the reaction kettle, pressurizing and heating; uniformly stirring the mixture; after the reaction is finished, cooling to room temperature, and placing the material in the reaction kettle in a distillation kettle for reduced pressure distillation; and distilling, cooling to room temperature, taking out a sample, and purifying to obtain the epoxidized soybean oil. The raw materials are purified before preparation, so that the purity of the prepared epoxidized soybean oil is higher; oxygen is directly used for a reaction, and the problem that the adding temperature of hydrogen peroxide is difficult to control can be avoided.

Description

technical field [0001] The invention belongs to the technical field of food production and processing, and in particular relates to a preparation method and a control system of novel epoxidized soybean oil. Background technique [0002] At present, epoxidized soybean oil is a chemical product obtained after oxidation treatment of 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: Good compatibility with PVC resin, low volatility and small 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 . At present, the methods for producing epoxidized soybean oil are: transesterification, ozone, and hydroformylation, but the...

AI Technical Summary

Problems solved by technology

The current production methods of epoxidized soybean oil are: transesterification method, ozone method, and hydroformylation method, but the reaction conditions for preparing epoxidized soybean oil by these three methods are high, and they are not suitable for large-scale industrial production.

[0003] Through the above analysis, the problems and defects in the prior art are: the reaction conditions for the preparation of epoxy soybean oil by transesterification, ozone, and hydroformylation are high, and are not suitable for large-scale industrial production; Relevant technical solutions for controlling the production process of oxygenated soybean oil
