Epoxidized soybean oil plasticizer and production method thereof

Abstract

The invention relates to an epoxidized soybean oil plasticizer, in particular to an epoxidized soybean oil plasticizer and a production method thereof. The epoxidized soybean oil plasticizer is characterized by being prepared from raw materials in percent by weight: 95-100 parts of soybean oil, 50-78 parts of hydrogen peroxide with the weight concentration of 27-50 percent and 8-13 parts of formic acid with the weight concentration of 85 percent. The epoxidized soybean oil plasticizer disclosed by the invention is prepared by adopting the following steps of: adding weighted soybean oil and the formic acid into a reaction kettle, then dropwise adding the hydrogen peroxide for epoxidized synthesis, carrying out water washing after the reaction is ended, and finally dewatering by distilling to obtain the finished product. The epoxidized soybean oil plasticizer and the production method thereof have the beneficial effects of safe and reliable production process, simpleness, convenience and feasibility in production operation, short period, low cost, high quality, high yield, small pollution and capability of completely achieving the idealized purpose.

Description

(1) Technical field [0001] The invention relates to an epoxy soybean oil plasticizer, in particular to an epoxy soybean oil plasticizer and a production method thereof. (2) Background technology [0002] At present, the production methods of epoxidized soybean oil mainly include solvent method and solvent-free method. [0003] The solvent method uses benzene as a solvent, sulfuric acid as a catalyst, hydrogen peroxide is added dropwise under stirring, and the product is obtained by epoxidation reaction. This process uses benzene as a solvent. Although it has good solubility, fast reaction and low temperature, the production process is long and complicated, and the product quality is unstable. The epoxy value is only about 5%, and the yield is only about 85%. The cost is high, the equipment is large, the investment is large, the "three wastes" are difficult to deal with, and the solvent benzene has certain toxicity, so the non-toxicity of the product cannot be guaranteed.

Problems solved by technology

Although the solvent-free process has improved compared with the solvent process, its comprehensive benefits are not ideal, and there are still many deficiencies: on the one hand, due to its long production cycle (generally 12 hours), the daily production can only Two shifts are carried out intermittently, which seriously affects the full utilization and exertion of the production capacity of the equipment, thus causing the production of the enterprise to fail to operate normally according to the design capacity; Alkaline washing is easy to saponify, which increases the cost of the catalyst and reduces the yield. At the same time, the post-treatment is relatively complicated and the environmental pollution is serious; and there are high reaction temperature, accelerated side reactions, many reaction by-products, unstable product quality, and poor operation. Difficulty, low safety factor, long reaction time, darkened product color, high labor intensity, high energy consumption, large and difficult treatment of "three wastes", etc., have seriously affected the production and operation benefits and development prospects of enterprises, and it remains to be seen to further improve, perfect or enhance
