Problems solved by technology

The problem with this invention patent is that since the main components of kitchen waste oil are unsaturated fatty acids, saturated fatty acids and glycerin, and their ratios fluctuate greatly, when only simple activated carbon decolorization and deodorization treatment is performed, the refined kitchen waste oil The main ingredients have not changed, and the saturated fatty acid and glycerin ingredients lead to poor solubility
[0005] In addition, the Chinese invention patent with the publication number CN102293196 B discloses a method for preparing a pesticide solvent that replaces petroleum aromatic solvents. In this method, mixed fats are obtained by filtering and acidifying kitchen waste oils, and the obtained fats are mixed with normal After the esterification reaction of octanol, the mixed fatty acid n-butyl ester is obtained through deacidification and vacuum distillation. This invention patent also has the problem that the solvent composition is complicated and affects the solubility, and the cost of vacuum distillation equipment is relatively high. , the process is difficult to promote on a large scale
[0006] It can be seen that in the prior art, there are mainly complex components of recovered solvents prepared from kitchen waste oils and poor product gain effect, which limits its practical application in the field of pesticide solvents

Abstract

The invention discloses methyl esterified vegetable oil and an application thereof. According to the method, the methyl esterified vegetable oil is prepared by carrying out alkali refining purification and methyl esterification modification on kitchen waste grease, and the methyl esterified vegetable oil can be applied to a pesticide environment-friendly solvent, a synergist and a coating cosolvent. Animal oil components in the kitchen waste grease are removed through an alkali refining process, the complexity of product components is reduced, and the pesticide effect of herbicide and insecticide products is obviously improved when the product is applied to herbicides and insecticides. Compared with unmodified vegetable oil, the methyl esterified vegetable oil has the advantages that the methyl esterification modification technology has an obvious gain effect, and a large amount of petroleum resources can be saved.

Description

technical field [0001] The invention relates to a modified solvent, and in particular provides a preparation method of a modified solvent using kitchen waste oil as a raw material and an application of the modified solvent. Background technique [0002] At present, there are three main methods for the comprehensive utilization of kitchen waste oil in my country: one is to simply process and purify the kitchen waste oil, and directly use it as low-grade industrial oleic acid, stearic acid and industrial oil. The second is to use kitchen waste oil to prepare phosphorus-free washing powder. The third is to produce biodiesel (fatty acid methyl ester) by alcoholylysis of kitchen waste oil. [0003] In the preparation process of pesticides and insecticides commonly used in crops, organic substances are needed as reaction solvents. The widely used organic solvents mainly include benzene, toluene, xylene, methanol, and dimethylformamide. These organic solvents will cause harm to t...
