Embodiment Construction

[0016] Add 150 g of powdered saponified higher fatty primary alcohol mixture, containing octacosanol 10.5 %. Turn on the raw material preheating device, heat up to 88°C to melt, and keep the temperature constant. Turn on the cooling device, keep the cooling temperature at 30°C, add liquid nitrogen into the cold trap, turn on the rotary vane vacuum pump and the oil diffusion pump to make the operating pressure of the system reach 0.1Pa, turn on the precision constant temperature tank for evaporating materials to conduct heat transfer oil Heating, so that the temperature is stabilized at the required evaporation temperature of 130 ° C, then start feeding, the feed rate is 150g / h, the rotating speed of the wiper is 180rmp, after the distillation process is over, 30.6g of distillate is obtained, and the distillation raffinate 119.4g; the distilled raffinate obtained in the first distillation was used as a raw material and distilled at an evaporation temperature of 130°C to obtain...

Abstract

The present invention discloses a high-grade fatty primary alcohol mixture extracted from beeswax and its separation purification method, belonging to the separation, purification and deep-processingtechnology of beeswax. The described high-grade fatty primary alcohol mixture is the C24-C34 alkylalcohol mixture containing octacosyl alcohol to 60%-90%. The separation purification method of said mixture uses the saponified beeswax as raw material and adopts the molecular distillation process to obtain the invented product. Its technical characteristics are that it adopts the liquid residue as raw material for next distillation, and makes repeated distillation process and definition of operation techonlogical parameters. Said invented method is simple and its yield rate is high.

Description

technical field [0001] The invention relates to a method for extracting a mixture of higher fatty primary alcohols from beeswax, in particular to a method for separating and purifying a mixture of higher fatty primary alcohols from saponified beeswax, which belongs to the separation and purification deep processing technology of beeswax. Background technique [0002] Higher fatty primary alcohol mixtures mainly exist in natural products such as cane wax, bran wax, wheat germ oil, and beeswax. CN1098906A, CN00108525.5, US6225354 B1, US5856316, EP0488928 and other patents have reported the effect of high-grade fatty primary alcohol mixture (main component is octacosanol): calcitonin formation accelerator, which can be used to treat hypercalcemia Osteoporosis; treat high cholesterol and high lipoprotein blood type, stimulate the sexual behavior of animals and humans; cosmetics containing octacosanol can promote skin blood circulation and activate cells, have anti-inflammatory, ...
