Examples
Embodiment 1
[0024] (1) Mix and heat 20 g of methyl soybean oil fatty acid and 2 g of formic acid, heat up to 50° C., add dropwise a mixture of 0.2 g of concentrated sulfuric acid and 9 g of hydrogen peroxide (30%), and finish the reaction after 5 hours. Transfer the reaction mixture to a separatory funnel, take the upper layer liquid, add 30mL of water, wash until neutral, and obtain epoxidized biodiesel. (2) Mix 10g of epoxidized biodiesel with 40g of butanol, add 0.2g of concentrated sulfuric acid, stir and react at 25°C for 7h, add 15mL of 5% Na 2 CO 3 After washing, pour it into a separatory funnel to separate the ester layer, and steam out the low boiling point components to obtain branched biodiesel. The comparison of cloud point and AOM value between branched biodiesel and raw biodiesel is shown in the table

[0026]
Embodiment 2
[0028] (1) Mix and heat 20g rapeseed oil fatty acid methyl ester and 4g formic acid, heat up to 60°C, add dropwise a mixture of 0.4g concentrated phosphoric acid and 12g hydrogen peroxide (30%), and finish the reaction after 3h. Transfer the reaction mixture to a separatory funnel, take the upper layer liquid, add 25 mL of water, wash until neutral, and obtain epoxidized biodiesel.
[0029] (2) Mix 10g of epoxidized biodiesel with 30g of ethanol, add 0.1g of concentrated sulfuric acid, stir and react at 30°C for 4h, add 20mL of 5% Na 2 CO 3 After washing, it was poured into a separatory funnel to separate the ester layer, and the branched biodiesel was obtained after the low boiling point components were evaporated.

Embodiment 3
[0033](1) Mix and heat 20g rapeseed oil fatty acid ethyl ester and 4.5g formic acid, heat up to 55°C, add dropwise 0.25g concentrated phosphoric acid, 0.25g concentrated sulfuric acid and 14g hydrogen peroxide (30%) mixed solution, and finish the reaction after 4.5h . Transfer the reaction mixture to a separatory funnel, take the upper layer liquid, add 40 mL of water, wash until neutral, and obtain epoxidized biodiesel.
[0034] (2) Mix 10g of epoxidized biodiesel with 28g of propanol, add 0.15g of concentrated sulfuric acid, stir and react at 40°C for 3.5h, add 30mL of 5% Na 2 CO 3 After washing, it was poured into a separatory funnel to separate the ester layer, and the branched biodiesel was obtained after the low boiling point components were evaporated.
