Abstract
The preparation method of Chinese tallow tree fat and Chinese catalpa oil and purposes belong to oil chemical technology.With the Chinese tallow tree seed is raw material, takes the method with the lixiviate of twice difference of organic solvent, makes Chinese tallow tree fat and Chinese catalpa oil.The product that present method makes does not mix mutually, the purity height.Its Chinese tallow tree grease article is a good raw material of producing cocoa butter equivalent.
Description
The invention belongs to oil chemical technology, relating to a kind of is the processing method that raw material is produced Chinese tallow tree fat and Chinese catalpa oil with the Chinese tallow tree seed, and this method makes the special purpose of Chinese tallow tree grease article.
The Chinese tallow tree seed is the fruit that the distinctive woody oleiferous plants plant-Chinese tallow tree of China is tied, and it is a kind of seed that had not only contained Chinese tallow tree fat but also contained Chinese catalpa oil.The structure of seed is divided into mesocarp part and seed shell, seed benevolence part.The contained Chinese wax shape material of mesocarp part is a Chinese tallow tree fat, and it is not only important source material ， And that produces candle, soap, spices, stearic acid, glycerine and the desirable feedstock of still producing cocoa butter equivalent.The contained oily mater of seed benevolence part is a Chinese catalpa oil, and it is a raw material of producing high-quality paint, printing ink.
Prior art takes traditional pressing method to produce Chinese tallow tree fat and Chinese catalpa oil, and this method is earlier Chinese tallow tree seed mesocarp part partly to be separated with seed shell, seed benevolence, separate substance is squeezed respectively obtain Chinese tallow tree fat and Chinese catalpa oil production again.The separation circuit of this method is to adopt artificial or mechanical way to realize, therefore is difficult to reach mesocarp and separates fully with seed shell, seed benevolence.In actual production, mesocarp and seed shell, seed the benevolence amount of mixing mutually are very big, so that cause product purity to reduce.This not only wastes raw material, but also for the further deep processing and utilization of product causes difficulty, the more important thing is with this Chinese tallow tree fat prod that contains a large amount of Chinese catalpas oil and produce cocoa butter equivalent, is difficult to obtain qualified product.
The object of the present invention is to provide a kind of processing method of chemistry to extract Chinese tallow tree fat and Chinese catalpa oil respectively, reach Chinese tallow tree fat and separate fully, so that provide the fine raw material for producing cocoa butter equivalent with Chinese catalpa oil.
Main points of the present invention are, the Chinese tallow tree seed adds organic solvent after removal of impurities, carry out lixiviate first time And control extraction time at a certain temperature, filter, filtrate gets the Chinese tallow tree grease article through removing organic solvent, filters gained seed slag through break process, add organic solvent, carry out the lixiviate second time at a certain temperature, filter, remove organic solvent and get the Chinese catalpa oil prod.
The present invention utilizes and is separated with the structure that one deck is difficult for the hard seed shell that soaked into by organic solvent between Chinese tallow tree seed mesocarp and the seed benevolence, take organic solvent respectively the method for lixiviate extract Chinese tallow tree fat and Chinese catalpa oil, Chinese tallow tree fat is reached fully aborning with Chinese catalpa oil separates.The product purity height that this method is produced does not mix mutually.
Specific embodiments of the invention are:
The Chinese tallow tree seed raw material is carried out removal of impurities to be handled, add organic solvent, organic solvent adopts sherwood oil, acetone or normal hexane (soybean solvent oil, industrial naptha), raw material and organic solvent weight ratio are 1: 0,5～1, be heated to 30～80 ℃ and carry out the lixiviate first time, extraction time 3～8 hours, filter, filtrate gets the Chinese tallow tree grease article through removing organic solvent, filter gained seed slag through break process, add organic solvent, organic solvent adopts sherwood oil, acetone or normal hexane (soybean solvent oil, industrial naptha), seed slag and organic solvent weight ratio are 1: 0.6～1, be heated to 30～80 ℃ and carry out the lixiviate second time, extraction time 3～6 hours filters, and removes organic solvent and gets the Chinese catalpa oil prod.
The Chinese tallow tree fat that this method is produced does not contain Chinese catalpa oil and mixes, and is the good raw material of extraction of cocoa butter.
Claims (4)
1, the preparation method of a kind of Chinese tallow tree fat and Chinese catalpa oil, with the Chinese tallow tree seed is raw material, adopt the organic solvent leach extraction method, the invention is characterized in raw material after removal of impurities is handled, add organic solvent and carry out the lixiviate first time, filter, filtrate gets the Chinese tallow tree grease article through removing organic solvent, filters gained seed slag through break process, adds organic solvent and carries out the lixiviate second time, filter, remove organic solvent and get the Chinese catalpa oil prod.
2, the lixiviate first time according to claim 1, it is characterized in that the organic solvent that adopts is sherwood oil, acetone or normal hexane (soybean solvent oil, industrial naptha), the weight ratio of raw material and organic solvent is 1: 0,5～1, and extraction temperature is 30～80 ℃, and extraction time is 3～8 hours.
3, the lixiviate second time according to claim 1, it is characterized in that the organic solvent that adopts is sherwood oil, acetone or normal hexane (soybean solvent oil, industrial naptha), the weight ratio of seed slag and organic solvent is 1: 0,6～1, and extraction temperature is 30～80 ℃, and extraction time is 3～6 hours.
4, the Chinese tallow tree grease article of producing according to the described method of claim 1 is characterized in that it is used to produce cocoa butter equivalent.
