Embodiment 1

[0019] A preparation method of epoxidized soybean oil derivatives is characterized in that the preparation method is: in an autoclave, add epoxidized soybean oil, anhydrous methanol, solvent, water and a catalyst, and evacuate with nitrogen at 2°C / The heating rate is 1 min, the temperature is raised to 100°C, the reaction pressure is self-generated pressure, the reaction is 12h, the solvent is evaporated, and the unreacted catalyst is washed with saturated sodium sulfate solution to completely remove the unreacted catalyst, and the water is removed by rotary evaporation under reduced pressure. ;

[0020] Wherein the weight ratio of each component is: epoxidized soybean oil: anhydrous methanol=10: 13;

[0021] Epoxidized soybean oil: solvent=10:11;

[0022] Epoxidized soybean oil: water=10:2;

[0023] Epoxidized soybean oil:catalyst=10:0.2.

[0024] As a further solution of the invention: the solvent is n-hexane, isopropanol, and dimethyl sulfoxide.

[0025] As a further s...

Embodiment 2

[0028] In the embodiment of the present invention, the difference from embodiment 1 lies in the difference in the weight parts of raw materials, and other conditions are the same.

[0029] A preparation method of epoxidized soybean oil derivatives is characterized in that the preparation method is: in an autoclave, add epoxidized soybean oil, anhydrous methanol, solvent, water and a catalyst, and vacuumize with nitrogen at 10 ° C / The heating rate is 1 min, the temperature is raised to 160°C, the reaction pressure is autogenous pressure, the reaction is 20h, the solvent is evaporated, and the saturated sodium sulfate solution is washed to completely remove the unreacted catalyst, and then the water is removed by rotary evaporation under reduced pressure, and the suction is filtered under reduced pressure ;

[0030] Wherein the weight ratio of each component is: epoxidized soybean oil: anhydrous methanol=10: 14;

[0031] Epoxidized soybean oil: solvent=10:13;

Abstract

The invention discloses a preparation method of an epoxidized soybean oil derivative. The invention belongs to the technical field of soybean oil. The preparation method disclosed by the invention issimple and efficient; the prepared epoxidized soybean oil derivative can be used as a common auxiliary plasticizer; the excellent performances of low value, no toxicity, wide raw material source and the like are realized; material flexibility can be improved obviously, excellent plasticizing effect is achieved, material defects are improved; and in addition, through modification on epoxy groups, the dependence on petrochemical industry and coal chemical industry derivatives can be reduced, the requirement of environmental protection can be met, and the epoxidized soybean oil derivative can beused as a chemical synthesis raw material in preparation of polyurethane, plasticized plastics and other materials.

Description

technical field [0001] The invention belongs to the technical field of soybean oil, in particular to a preparation method of epoxidized soybean oil derivatives. Background technique [0002] Soybean oil is a kind of oil extracted from soybeans, usually we call it "soybean salad oil", and it is one of the most commonly used cooking oils. The longest shelf life of soybean oil is only one year. The better the quality, the lighter the soybean oil should be, which is light yellow, clear and transparent. And there is no sediment, no beany smell, and high-quality soybean oil with a temperature below zero degrees Celsius will have grease crystallization. Epoxidized soybean oil is a widely used polyvinyl chloride plasticizer and stabilizer, which has good heat and light stabilization. This product has good compatibility with polyvinyl chloride, low volatility and no toxicity. This product can be used in almost all polyvinyl chloride products. Using 2~3 parts of this product in ge...
