Embodiment 1
[0033] (1) Take 100g of hydrogen peroxide, 3g of formic acid, 0.1g of phosphotungstic heteropolyacid and 0.2g of manganese benzoate with a concentration of 55%, add them to the autoclave successively, stir for 2h at a speed of 200rpm, cool to 50°C, and obtain peroxyformic acid mixture;
[0034] (2) in the formic acid peroxide mixture that step (1) obtains, slowly drip 120g soybean oil, control the flow rate of soybean oil, make it drop completely in 0.8h; During the dropping process, feed 10L oxygen, control The stirring speed is 200rpm, the temperature is 60°C, the pressure is 0.9Mpa, the reaction is 2h, and the crude epoxy soybean oil is obtained;
[0035] (3) The crude epoxidized soybean oil obtained in step (2) is subjected to alkali washing, water washing, and vacuum distillation according to conventional technical means to obtain the finished epoxidized soybean oil.
Embodiment 2
[0037] (1) Take 65% hydrogen peroxide 100g, 10g formic acid, 0.3g phosphotungstic heteropoly acid and 0.6g manganese benzoate, add them to the autoclave successively, stir for 1h at a speed of 450rpm, cool to 60°C, and get peroxyformic acid mixture;
[0038] (2) In the peroxyformic acid mixture obtained in step (1), slowly add 180g of soybean oil dropwise, control the flow rate of soybean oil, and make it drop completely within 1h; during the dropwise addition, feed 50L of oxygen and control the stirring The speed is 450rpm, the temperature is 60°C, the pressure is 1.2Mpa, the reaction is 1h, and the crude product of epoxidized soybean oil is obtained;
[0039] (3) The crude epoxidized soybean oil obtained in step (2) is subjected to alkali washing, water washing, and vacuum distillation according to conventional technical means to obtain the finished epoxidized soybean oil.
Embodiment 3
[0041](1) Take 100g of hydrogen peroxide, 8g of formic acid, 0.05g of phosphotungstic heteropolyacid and 0.25g of manganese benzoate at a concentration of 60%, add them to the autoclave successively, stir for 1h at a speed of 300rpm, and cool to 55°C to obtain peroxyformic acid mixture;
[0042] (2) in the formic acid peroxide mixture that step (1) obtains, slowly drip 160g soybean oil, control the flow rate of soybean oil, make it drop completely in 0.5h; During the dropping process, feed 15L oxygen, control The stirring speed is 450rpm, the temperature is 60°C, the pressure is 1.0Mpa, the reaction is 1.5h, and the crude epoxy soybean oil is obtained;
[0043] (3) The crude epoxidized soybean oil obtained in step (2) is subjected to alkali washing, water washing, and vacuum distillation according to conventional technical means to obtain the finished epoxidized soybean oil.
