Process for producing chloro-fatty acid methyl ester by utilizing biodiesel

Abstract

The invention discloses a process for producing chloro-fatty acid methyl ester by utilizing biodiesel. The process for producing the chloro-fatty acid methyl ester by utilizing the biodiesel comprisesthe synthetic steps that step 1-6, and in the reaction preparation for the producing the chloro-fatty acid methyl ester by utilizing the biodiesel, the preparation of a preparation reaction is carried out through step 2-5, so that the cost of the preparation through multiple steps is reduced, the cost of capital input is reduced, and preparation equipment is reduced, so that the labor cost is effectively reduced, and the preparation efficiency is effectively improved; in the preparation, protection is carried out through nitrogen, so that a reaction with an air substance is avoided, and the reaction is more efficient and sufficient; the chloro-fatty acid methyl ester prepared through the four steps has good advantages of low cost, high flashing point, low condensation point, no physiological toxicity and the like, has outstanding comprehensive performance, and has more market competition compared with a common plasticizer DOP.

Description

technical field [0001] The invention belongs to the technical field of biodiesel, and in particular relates to a process for producing chlorinated fatty acid methyl esters by using biodiesel. Background technique [0002] Biodiesel refers to vegetable oil (such as rapeseed oil, soybean oil, peanut oil, corn oil, cottonseed oil, etc.), animal oil (such as fish oil, lard, tallow, sheep oil, etc.), waste oil or microbial oil and methanol or ethanol Fatty acid methyl or ethyl esters formed by ester conversion. Biodiesel is a typical "green energy", which has the characteristics of good environmental performance, good engine start performance, good fuel performance, wide source of raw materials, and renewable properties. Vigorously developing biodiesel has important strategic significance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution. [0003] The fuel performance of biodiesel is close t...
