Apparatus and method for producing policosanol having specific chromatographic fingerprint |
| abstract |
The present disclosure provides an apparatus and method for producing a policosanol having a specific chromatographic fingerprint. The apparatus of the present disclosure has a feed tank and receiving tanks which are connected to a vacuum system. The method of the present disclosure is carried out by a high vacuum rectification process and includes: firstly, feeding a saponified crude alkanol into a melting tank in which the material is melted and then flows into the feed tank, and then injecting the material into a rectifying still using a delivery pump, followed by first rectification under vacuum condition and sequential collection of fractions at different phases from the tower top and stillage residue from the tower bottom; and after the completion of the rectification of the first batch crude product, carrying out second feeding on the basis of consistent vacuum in the feed tank and the rectifying tower. |
