Abstract

The invention discloses a method for synthesizing biodiesel in a eutectic system. The biodiesel is obtained by taking vegetable oil and methanol as raw materials and performing stirring and heating at a normal pressure in the eutectic system composed of N-sulfopropyl-N,N,N-trihydroxyethyl ammonium and glycerol. The method disclosed by the invention has the following advantages: (1) a sodium hydroxide catalyst is adopted, and is low in cost, high in catalytic activity and little in dosage; (2) the reaction condition is mild to ensure that reaction can be carried out at a normal pressure and a methanol refluxing temperature; (3) a eutectic solvent in the composition eliminates emulsification and then the process flow is simplified; (4) the product is high in purity and few in impurity; and (5) a eutectic catalytic system composed of the eutectic solvent and sodium hydroxide facilitates recycling, and does not contain halide ions, thereby being safe and reliable for environment and metal equipment.

Description

a technical field

[0001] The invention relates to a method for synthesizing biodiesel in a deep eutectic system, and belongs to the technical field of chemical material preparation. This method is suitable for the occasion of synthesizing biodiesel with vegetable oil and methanol as raw materials. Two background technology

[0002] As a new type of renewable and clean energy, biodiesel is a liquid fuel made from oil crops, oil palm and pistachio and other oil forest fruits, engineering microalgae and other oil aquatic plants, animal fats, and waste cooking oil. It is a high-quality petroleum diesel substitute. Biodiesel is a typical "green energy". Vigorously developing biodiesel has important strategic significance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution.

[0003] Synthetic biodiesel is a transesterification reaction that can be catalyzed by both acid and base. Usually, stron...
