-
Paragraph 0012, (2018/03/01)
The invention discloses a chemical synthesis method for 1,2-fatty diglyceride with a customizable structure. The method is characterized by comprising the following steps: (a) weighing a certain amount of 3-glycerol-chlorohydrin and sodium acetate and adding into a reactor with a reflux condensation apparatus so as to obtain gylcerol monoacetate; (b) selecting fatty acid methyl ester types of biodiesel according to customization needs in presence of a base catalyst, and heating and refluxing the gylcerol monoacetate with the biodiesel in an organic solvent so as to obtain triglyceride; and (c) dissolving the triglyceride obtained in the previous step in a proper amount of methanol, adding potassium carbonate to react at room temperature, extracting with an organic solvent, and recrystallizing, thereby obtaining the high-purity (more than 90%) 1,2-fatty diglyceride. The method disclosed by the invention is simple and convenient in synthetic route, simple in after-treatment and high in total yield (more than 75%), and the 1,2-fatty diglyceride can be effectively synthesized.
