Abstract

The invention provides a method for preparing camellia-oil fatty acid esters. The method comprises the following steps: adding a bio-enzyme catalyst in a mixed solution of camellia oil, alcohol and acosolvent, and carrying out an esterification reaction, thereby obtaining the camellia-oil fatty acid esters, wherein the cosolvent is selected from camellia-oil fatty acid esters such as camellia-oilfatty acid ethyl ester, camellia-oil fatty acid triglyceride, camellia-oil fatty acid octyl ester and camellia-oil fatty acid ethyl hexyl ester. According to the method, the cosolvent the same as thecamellia-oil fatty acid esters is added during an esterification reaction between the camellia oil and the alcohol, the cosolvent has good intersolubility with both the camellia oil and the alcohol,thus, reactants can be mixed uniformly, and the rate of reaction and conversion ratio of reaction can be remarkably increased.

Description

technical field [0001] The invention belongs to the field of preparation of daily chemical raw materials, and in particular relates to a preparation method of camellia oil fatty acid ester. Background technique [0002] Grease refers to oily raw materials that are insoluble in water. It is mainly used as an emollient in daily chemicals and is an indispensable part of skin care products. Lipids, rehydrate dry skin and hardened cuticles, restoring softness and elasticity to the cuticles. Commonly used oils are synthetic oils and natural oils. Among them, synthetic oils and esters have a wider range of applications than natural oils and esters due to their stable chemical properties and diverse structures. [0003] Camellia oil is one of the oldest woody edible vegetable oils in my country. No pesticides or chemical fertilizers are used during the entire growth process of the Camellia oleifera tree. The camellia oil produced does not contain erucic acid, cholesterol, aflatox...
