Lacquer-wax oil fatty acid ester and preparation method thereof

Abstract

The invention discloses a lacquer-wax oil fatty acid ester, which comprises the following raw materials in percentage by mass: 20 to 35 percent of lacquer-wax oil, 40 to 45 percent of fatty alcohol, 1 to 6 percent of catalyst, and 20 to 40 percent of solvent, wherein the total percentages of the raw materials is equal to 100 percent. The method for preparing the lacquer-wax oil fatty acid ester comprises the following steps: putting the lacquer-wax oil and the fatty alcohol into a reactor, wherein the reactor is provided with a reflux unit; heating the obtained mixture to 85 to 90 DEG C, thencarrying out heat preservation for 30 to 60 minutes; adding the catalyst and the solvent into the reactor to carry out reflux reaction for 3 to 5 hours so as to obtain lacquer-wax oil fatty acid ester solution; carrying out dehydration on the obtained lacquer-wax oil fatty acid ester solution so as to remove the solvent, then cooling the obtained product to room temperature, and drying the obtained product so as to obtain the lacquer-wax oil fatty acid ester. The prepared lacquer-wax oil fatty acid ester is a necessary chemical raw material or intermediate in many chemical industries, and an important raw material for preparing high-grade furniture waxes, fresh-keeping waxes and automobile waxes as well as high-class cosmetics and health care products. Because 150 to 200t of products of the lacquer-wax oil fatty acid ester is demanded in our country annually, the products of the lacquer-wax oil fatty acid ester are imported basically, and the import price of the ester product of the lacquer-wax oil fatty acid ester is RMB *** / t, the lacquer-wax oil as an important chemical raw material gradually replaces palm oils, and the market prospect thereof is wide.

Description

technical field [0001] The invention belongs to the field of applied chemical technology, relates to the development and utilization technology of lacquer tree resources, in particular to a high-grade lacquer wax oil fatty acid ester whose main raw material is lacquer wax (oil) extracted from pure natural lacquer tree fruit and a preparation method thereof. Background technique [0002] The lacquer tree is a special resource in China, and the raw lacquer production is its main utilization method, and the lacquer seed is the fruit resource of the lacquer tree. There are more than 500 million lacquer trees in China, with more than 200 varieties, of which more than 100 million lacquer trees of more than 30 varieties can produce seeds, and the annual output of lacquer seeds is more than 1.5 million tons, ranking first in the world. . According to expert forecasts, nearly 1.5 to 2 billion yuan of lacquer seed resources in China have not been processed and utilized every year. T...
