Problems solved by technology

[0013] 3. In white wax, in addition to the ester mixture mainly composed of higher monobasic acids and monohydric alcohols, there are still a small amount of palmitic acid, stearic acid, myristic acid, linoleic acid, oleic acid, linolenic acid and unsaturated Esters, these substances are acid-corrupted under the oxidation of oxygen in the air and the catalysis of iron, copper, manganese, zinc and other metal ions, resulting in low-level fatty acids, aldehydes and ketones and other rancid substances, which seriously affect the color and smell of white wax
[0014] At present, my country's white wax processing still uses the wax boiling and wax steaming methods hundreds of years ago. The technology is outdated, and the product quality is poor. It is basically a crude product (hair white wax). and other industries, especially the needs of the international market, therefore, there is an urgent need to provide a simple white wax refining and purification processing technology

Embodiment 1

[0041] 1) Add white wax to a melting wax kettle with clear water, control the liquid-solid ratio to 3:1, that is, control the weight ratio of clear water to white wax to 3:1, heat up, stir slowly, and the stirring rate is 100 rpm / Minute;

[0042] 2) Add an appropriate amount of phosphoric acid solution with a mass percentage concentration of 30% after the white wax is completely melted, so that the phosphoric acid concentration of the water in the kettle is 2%, heat and stir at a stirring rate of 100 rpm, and keep the mixed liquid in the wax-melting kettle. boil for 30 minutes;

[0043] 3) Stop heating, continue stirring for 10 minutes, then cool and let the wax solidify;

[0044] 4) Drain off the pickling solution at the bottom, and blow dry the surface moisture of the white wax;

[0045] 5) In a vacuum state with a vacuum degree of -0.05~-0.08MPa (that is, with one atmospheric pressure as 0, the vacuum degree relative to one atmospheric pressure is -0.05~-0.08MPa), heat and...

Abstract

The invention discloses a refined method of Chinese wax, comprising 1) acid cleaning to removal impurity, which means acidic solution is adopted to removal the phospholipids and micro metal ion in the liquated raw wax; 2) adsorbing to decolor, which means the floridin and the silicon dioxide are adopted to decolor and removal the protein in the liquated raw Chinese wax under vacuum state. The refined method of Chinese wax has the advantages of simple technique and convention operation. The appearance of the made Chinese wax and the physicochemical index can reach the first wax standard set by < trading cooperative standards of P.R.C- Chinese wax [GH011-80] >, and also has the advantages of increasing the productive rate and the purity of the Chinese wax and lowering the productivity energy consumption.

Description

technical field [0001] The invention relates to a method for refining fatty substances, in particular to a method for refining wax. Background technique [0002] Chinese Insect Wax (Chinese Insect Wax) is a colony of male larvae of Ericerus Pela (chavannes) that inhabits plants of the Oleaceae family, Fraxinus Chinensis Roxb of the genus Fraxinus or the genus Ligustrum. The white wax secreted by Ligustrum Lucidum Ait branches during growth and development is a pure natural polymer compound. Because of its high strength, high melting point, good fluidity, stable physical and chemical properties, and moisture-proof, anti-corrosion, glossy, lubricating and other characteristics, it is mostly used in high-grade chocolate, high-grade floor wax and car wax, food packaging, drug coating, cosmetics ( Lipstick, pomade, skin care products), photosensitive materials for color copiers and other products are regarded as treasures by countries all over the world. [0003] Because insect...
