Abstract
The invention discloses a production method for preventing fatty alcohol-polyoxyethylene ether from yellowing. The method comprises the following steps that at first, fatty alcohol and a catalyst reacts with ethylene oxide, and fatty alcohol-polyoxyethylene ether is obtained; then, the temperature of fatty alcohol-polyoxyethylene ether just subjected to the reaction is adjusted to range from 70 DEG C to 80 DEG C; then, an oxygen bleaching agent is added, fatty alcohol-polyoxyethylene ether and the oxygen bleaching agent are stirred and mixed to be uniform; at last, the temperature of fatty alcohol-polyoxyethylene ether is decreased to range from 50 DEG C to 60 DEG C, and packing is conducted. The produced fatty alcohol-polyoxyethylene ether can be effectively prevented from yellowing, the storage condition and cost are lowered, and the storage time is prolonged.
Description
Technical field：
The present invention relates to belong to AEO production technology, be that one prevents AEO from turning yellow
Production method.
Background technology：
The AEO of currently the majority can cause its colour changed into yellow because of storing improper, thus affects product
Outward appearance, the sale to product brings adverse influence.Therefore, the necessary lucifuge of depot fat alcohol APEO, and store at the moon
The dry place of airing.The high temperature time must also reduce storage room temperature, and unsuitable long-time storage.Affect AEO face
The yellow main cause of discoloration has two：One is, aborning fatty alcohol and oxirane in course of reaction with air generation oxygen
Change reaction, thus cause AEO its colour changed into yellow.This belongs to uncontrollable factor.Two are, aliphatic alcohol polyethenoxy
Oxygen generation oxidation reaction when storing and in air for the ether, thus cause AEO to turn yellow.Fatty alcohol
APEO its colour changed into yellow can affect the using effect that some color requires high product to a certain extent, also can be to company
Sale bring disadvantageous factor, affect corporate image, cause damage to enterprise.
Content of the invention：
The technical problem to be solved is to provide one and is prevented effectively from AEO at storing process
Middle flavescence prevent the production method that AEO turns yellow.
The technical solution of the present invention is to provide a kind of production method preventing AEO from turning yellow, it
Comprise the following steps：First, fatty alcohol adds catalyst and reacting ethylene oxide, obtains AEO；Then, just
The temperature of completely reacted AEO is adjusted to 70-80 DEG C；Then, oxygen bleaching agent is added, by fatty alcohol polyoxy second
Alkene ether and oxygen bleaching agent are uniformly mixed；Finally, carry out after the temperature of AEO being cooled to 50 DEG C-60 DEG C
Packaging.
The AEO that the present invention produces reduces storage request, the poly alkyl alcohol producing by present technology
Oxygen vinethene must be stored in the shady and cool indoor being dried and wanting lucifuge, and the AEO being produced with this invention is
Making to be placed on outdoor also will not variable color；Reduce storage cost, store with the AEO that present technology produces
When environment temperature can not be too high, therefore surrounding environment must be lowered the temperature during high temperature, and the fatty alcohol being produced with this invention
APEO under natural temperature will not variable color, so not needing to lower the temperature storeroom, thus reduce unnecessary life
Produce cost；Improve the storage time, the AEO producing by present technology can not long-time storage, not so also
AEO its colour changed into yellow can be caused to shade, then can be grown by the AEO that the method is produced
Time stores, and it has been observed that, stores the time with the AEO that the present invention is produced more raw than by present technology
The storage time lengthening of the AEO producing 5 times.
As preferably, the oxygen bleaching agent percentage by weight of addition is 0.1%-1%.
Further, pack after the temperature of AEO being cooled to 55 DEG C.
Detailed description of the invention：
Below in conjunction with detailed description of the invention, the invention will be further described：
Embodiment
A kind of production method preventing AEO from turning yellow, it comprises the following steps：First, fatty alcohol adds and urges
Agent and reacting ethylene oxide, obtain AEO；Then, the temperature just completely reacted AEO
Degree is adjusted to 70-80 DEG C；Then, the oxygen bleaching agent adding percentage by weight to be 0.8%, by AEO and oxygen bleaching
White agent is uniformly mixed；Finally, pack after the temperature of AEO being cooled to 55 DEG C.
Below only preferred embodiment of the present invention is described, but is not to be construed as limitations on claims.
Claims (3)
1. the production method preventing AEO from turning yellow, it is characterised in that it comprises the following steps：First,
Fatty alcohol adds catalyst and reacting ethylene oxide, obtains AEO；Then, just completely reacted fatty alcohol polyoxy
The temperature of vinethene is adjusted to 70-80 DEG C；Then, add oxygen bleaching agent, AEO and oxygen bleaching agent are stirred
Mix；Finally, pack after the temperature of AEO being cooled to 50 DEG C-60 DEG C.
2. the production method preventing AEO from turning yellow according to claim 1, it is characterised in that addition
