Abstract
The invention discloses a new method of extracting phytosterol from residual oil. A lower alcohol is employed for exchanging the phytosterol out from an aliphatic acid. A specific reaction general formula is described as follows, wherein R represents for a sterol side chain alkyl, R1 represents for an aliphatic acid alkyl and R2 represents for an alkyl of the lower alcohol. With the residual oil, the method employs the lower alcohol for exchanging the phytosterol out from the aliphatic acid through a transesterification reaction. Reaction conditions of the method are easy to achieve and an extraction process is free from discharging waste material.
Description
Technical field
The invention belongs to and in chemical purification technical field, particularly waste material, extract plant sterol novel method.
Background technology
The fatty acid ester of ubiquity plant sterol in natural fats and oils plant, in course of oil processing, it along with lipid acid together by vacuum distilling in lipid acid.Because the fatty acid ester of plant sterol belongs to apolar substance and boiling point is very high, be enriched in tankage in the course of processing, from these tankage, extract in the residual oil waste material after VE, fatty acid methyl ester and sterol and also contain a certain amount of sterol, but because existing method of purification is difficult to extract, be all therefore as waste disposal.
Summary of the invention
The present invention seeks to propose a kind of plant sterol novel method of extracting from residual oil.
In residual oil, extract plant sterol novel method, it is to utilize lower alcohol that plant sterol is exchanged from lipid acid, and concrete reaction expression is as follows:
Wherein: R=sterol side chain alkyl, R1=lipid acid alkyl, R
2the alkyl of=lower alcohol.
Reacting middle catalyst is highly basic or metal methoxylation compound; And the material proportion of reaction is: raw material: alcohol: catalyzer=1:(0.1-2): (0.01-0.2).
Reacting middle catalyst be in sodium hydroxide, potassium hydroxide, sodium methylate, potassium methylate any one, alcohol is one or mixture in methyl alcohol, ethanol, propyl alcohol, and reaction conditions is that normal temperature is to reflux, compressive reaction.
The present invention utilizes residual oil tankage exactly, by transesterification reaction, utilizes lower alcohol that plant sterol is exchanged from lipid acid, and reaction conditions is easily realized, and leaching process does not have trash discharge.
Embodiment
The present invention utilizes residual oil tankage, by transesterification reaction, utilizes lower alcohol that plant sterol is exchanged from lipid acid, and concrete reaction expression is as follows:
R=sterol side chain alkyl, R1=lipid acid alkyl, R
2the alkyl of=lower alcohol.
The catalyzer of this reaction is the highly basic such as sodium hydroxide, potassium hydroxide, or the metal methoxylation compound such as sodium methylate, potassium methylate; The reaction conditions of this reaction is that normal temperature is to reflux, compressive reaction; The alcohol that this reaction is used is mainly methyl alcohol, ethanol, propyl alcohol etc.; The material proportion of this reaction is: raw material: alcohol: catalyzer=1:(0.1-2): (0.01-0.2).
