Problems solved by technology

However, each feeding and discharging of this method needs to be carried out under normal pressure. Not only does it need to rebalance the vacuum degree and tower top temperature to collect products in sections, but it cannot realize continuous batch feeding and discharging, which prolongs the time for each batch. Rectification time, and each normal pressure-negative pressure switching operation, resulting in a large difference in the content of octacosanol in the same segment of each batch of products, which cannot guarantee stable product quality; and requires 2 to 3 rectifications process, the production efficiency is not high enough; finally, the process can only produce a specific content of octacosanol, and cannot produce pliol with a specific fingerprint

Embodiment 1

[0064] (1) A certain amount of rice bran wax is saponified into crude alcohol (fingerprint is 0.1-0.3% docosanol, 4-14% tetracosanol, 5-14% hexacosanol, 11-17% Stearyl alcohol, 17-23% triacontanol, 10-20% tricosanol, 12-20% tetracosanol, 10-14% triacetyl alcohol, 1-3% thirty octacanol) into the feed tank 1, put it into the feed tank 2 after heating the feed, then use the first delivery pump II-1 to accurately drive 18 kg into the rectifying still 4, and carry out the first batch of refining Distillation, the vacuum degree is 20-50Pa, the rectification kettle temperature is 230-250°C, and the reflux ratio is 1:5-20. Fractions are recorded as P101~P118 successively); P101 is collected in the first receiving tank 7, P102 is collected in the second receiving tank 8, and P103 is collected with the third receiving tank 9, while collecting P103, close the second valve I -2 and the third valve I-3, release P101 and P102 after the first receiving tank 7 and the second receiving tank 8...

Embodiment 2

[0073] Other operating conditions are consistent with Example 1, only rice bran wax saponification crude alcohol is replaced with beeswax saponification crude alcohol (0.5~7% eicosanol, 2~10% docosanol, 10~20% tetracosane Alcohol, 1~14% hexacosanol, 10~15% octacosanol, 35~70% triacontanol, 4~22% tricosanol, 0.1~1% tetracosanol ), carry out 10 batches of rectifying altogether, the cut that collects is carried out gas chromatographic detection, analyze each batch of cut and the component content of still residue, gained result is as shown in table 2:

Abstract

The invention relates to the technical field of oil extraction, separation and deep processing, and provides a device and method for producing specific fingerprints of prix alcohol. The device of the invention connects a feed tank and a receiving tank to a vacuum system to ensure the vacuum stability of the rectification tower Under these conditions, continuous batch feeding and discharging are realized without shutting down the operation to improve production efficiency; the method provided by the invention adopts a high vacuum rectification process, first put the saponified crude alcohol into the material tank, and then put it into the The feeding tank is then driven into the rectification kettle with a delivery pump, and the first batch of rectification is carried out under vacuum conditions. The fractions of each section are collected at the top of the tower in turn, and the residue of the still is collected at the bottom of the tower; the first batch of crude product rectification is completed, Under the condition that the vacuum of the feed tank is basically the same as the vacuum of the rectification tower, the next batch of feed is carried out. The method provided by the present invention has high separation efficiency, controllable fingerprint of pliol and stable quality, and can reach the required purity requirement of octacosanol in pliol only through one rectification process.

Description

technical field [0001] The invention relates to the technical field of oil extraction, separation and deep processing, and in particular to a device and method for producing pletilol with a specific fingerprint. Background technique [0002] Polyol, mainly derived from rice bran wax and beeswax, the main components include docosanol, tetracosanol, hexacosanol, octacosanol, triacontanol, and tricosanol When the mass ratio of each component is similar to the "fingerprint of traditional Chinese medicine", the synergistic effect of each component is the best, and various physiological activities are the best. Pulicol is mainly used in lipid-regulating drugs, health care products, high-end cosmetics and feed additives. [0003] At present, pliol is generally prepared from rice bran wax or beeswax through saponification, extraction (purification), filtration and other processes. Among them, the purification process is the key factor affecting the fingerprint of pliol. At present...
