Abstract
The invention discloses using low-purity cocker aldehyde as raw material, after being mixed with organic acid solvent, the catalysis of iodo salt is added, with being reacted 13 hours at a temperature of 30~100 DEG C, scrubbed, distillation produces high-purity cocker aldehyde.The cocker aldehyde purity that this manufacture method is obtained is high and old low, simple to operate, prepared by the high-purity that can be widely applied to cocker aldehyde.
Description
Technical field
The present invention relates to a kind of preparation method of high-purity compound, more particularly to a kind of preparation side of high-purity cocker aldehyde
Method.
Background technology
Cocker aldehyde, also known as trans -5- methyl -2- phenyl -2- hexenoic aldehydes, molecular formula:C13H16O;(CH3) 2CHCH2CH=
C (C6H5) CHO, structural formula is as follows:
In bitter cocoa, nut, honey, baking and green grass fragrance, natural product are present in the volatility thing for frying peanut and cocoa
In matter.Used mainly for preparation chocolate essence and cacao essence.
Cocker aldehyde can carry out aldol condensation by phenylacetaldehyde and isopentyl aldehyde and obtain, and it has cis and trans isomers, and suitable, anteiso-
Structure body ratio is about 1:9, the low-purity cocker aldehyde of content 90% or so is obtained through simple distillation, must can be contained through further rectifying purifying
95% or so finished product is measured, but its purity is still relatively low, it is impossible to meet the demand in market.Because cis-trans-isomer boiling point is high and boiling
Point is approached, therefore, and industry at present separates cis and trans isomers using rectifying, and raising finished product purity is extremely difficult, and yield rate is low, system
Cause high.
Above-mentioned cis-trans isomerization is a kind of important stereo-isomerism, and influence of the cocker aldehyde configuration to spices fragrance is very
Greatly, thus cis-trans-isomer configuration conversion be increasingly subject to research attention, pass through configuration conversion improve product quality.On double
The conversion of key configuration mainly includes three kinds of light isomery, hot isomery and catalytic isomerization, and wherein catalytic isomerization is increasingly by vast research
Person must pay attention to.
The content of the invention
It is an object of the invention to provide a kind of preparation method of high-purity cocker aldehyde, solve existing cocker aldehyde preparation method and obtain
The cocker aldehyde purity obtained is low, and further extracts difficulty greatly, the problem of cost is high.
The present invention solve technical problem technical scheme be:A kind of preparation method of high-purity cocker aldehyde, can with low-purity
Card aldehyde is raw material, after being mixed with organic acid solvent, adds the catalysis of iodo salt, with being reacted 1-3 hours at a temperature of 30~100 DEG C,
High-purity cocker aldehyde is produced through cooling washing, vacuum distillation.The mass ratio of the low-purity cocker aldehyde, organic acid and iodo salt is
100:100:0.1~1.
It is preferred that, the iodo salt is sodium iodide or KI.
It is preferred that, the organic acid is one kind in formic acid, acetic acid, propionic acid, butyric acid.
Compared with prior art, the present invention using the method for chemical catalysis by the syn-isomerism in existing low-purity cocker aldehyde
Body is converted into transisomer, so as to improve the purity of cocker aldehyde.The cocker aldehyde purity obtained by this method can reach
More than 98%, it disclosure satisfy that the demand of in the market.And this method reaction environment is simple, production and processing is convenient, and cost is low.
Embodiment
The present invention is described in further detail below by embodiment, but is not intended to limit the present invention.
Iodo salt used is that domestic analysis is pure in the present invention, is purchased from Chemical Reagent Co., Ltd., Sinopharm Group;Content
90% cocker aldehyde is directly from market purchasing.
Instrument of the present invention:GC-1690 gas chromatographs (Hangzhou section dawn chemical industry experimental instruments and equipment limited)
A kind of high-purity cocker aldehyde preparation method, in flask with three necks,round bottom, add iodo salt, 90% content cocker aldehyde,
Etc. quality organic acid, controlling reaction temperature is 30~100 DEG C, is reacted 1~3 hour, chromatogram tracking analysis.Work as cis and trans isomers
Than less than 2:98, reaction.Solvent is recovered under reduced pressure, residue uses general separation method, through cooling washing, is distilled in vacuum to give
Product, gas chromatographic analysis measures the content of cocker aldehyde more than 98%.Cooling cleaning function is to reduce significant loss, is removed residual
Stay solvent,;Because cocker aldehyde boiling point is high, using vacuum distillation, boiling point is reduced.
