Description
Technical field
The present invention relates to a kind of AEO glycidol ether and preparation method thereof, belong to fine chemical technology
Field.
Background technology
AEO glycidol ether, with fatty alcohol as initiator, epoxy addition obtains fatty alcohol polyoxy second
Alkene ether, then obtains AEO glycidol ether product by epoxy radicals end-blocking, and its molecular structure feature is：Point
It is APEO chain in the middle part of subchain, it has good flexibility and hydrophily, one end is alkyl carbon chain, has lipophile, separately
One end is epoxy radicals, has the good active group of reactivity, and structural formula is as follows：
Non-ionic oxyethylene chain is introduced surfactant, the solubility property of surfactant can be improved, acceptable
Increase resistance to ion stability, the performance that can make surfactant by oxygen ethylene unit number in Molecular regulator is more preferably.Fatty alcohol
First pass through epoxy addition and obtain AEO, then obtain AEO glycidol with epoxy radicals end-blocking
Ether, this product reactivity worth and hydrophily are all improved.AEO glycidol ether by with dimethylamine, chlorine
The reaction such as sodium acetate can obtain beet alkali ampholytic surface active agent；AEO glycidol ether and sodium sulfite
Carry out sulfonating reaction and can obtain fatty alcohol-ether sodium sulfate anion surfactant, it has good salt tolerance, excellent because having
Good antidecomposition ability and dispersiveness and be widely used；Formed for paint and coatings industry by addition, hydrolysis
Various reagents；It also can be used as additive, solvent, catalyst in epoxy resin, chemical fibre, plastics and rubber production simultaneously
And chain-transferring agent；Additionally, it still synthesizes a lot of industrial products, such as antistatic additive, emulsifying agent, plastic additive, cosmetics etc.
Important intermediate.
At present, producing alkyl capped polyether method both at home and abroad mainly divides one-step method and two-step method, ring-opening reaction and closed loop anti-
Referred to as one-step method should be carried out simultaneously, typically make polyethers and ECH in the presence of a phase transfer catalyst using alkali, through single step reaction
Obtain product, alkali is ring opening catalyst and closed loop removing hcl reaction reagent；Ring-opening reaction and ring-closure reaction substep enter
Row is referred to as two-step method, in acidic catalyst (H2SO4、HCl、HClO4、BF3·O(CH2CH3)2、SnC14Deng) catalysis under, polyethers
First be etherified open loop with ECH and obtain chloropharin ether intermediate product, then carried out with alkali remove hydrogen chloride closed loop to final product.One step
Method is few with respect to two-step process, total yield of products is high, process is simple；The multiple ECH of the easy addition of two-step method ring-opening reaction, forms neat
Polymers, intermediate product converts thoroughly in ring-closure reaction, causes final products epoxide number relatively low, water or solvent in ring-closure reaction
Participation will increase post-processing difficulty.
One-step method principle is as follows：
Two-step method principle is as follows：
Wherein：R is aliphatic alcohol polyethenoxy base；
M is alkali metal.
Under normal pressure aerobic conditions, polyethers (ROH) is exposed in strong alkali environment and is susceptible to multiple side reactions, generates some aldehyde
Ketone and have color class material, ECH autohemagglutination also can produce colour substance, and this will affect quality, the color of itself and downstream product
Pool and application performance.
The epoxy radicals end-blocking product boiling point of small molecule is relatively low, can obtain the preferable product of purity by vacuum distillation, such as specially
The process for purification that sharp CN100999507 announces.
During document JAOCS 78,423 429 (April 2001) synthesizing epoxy base end-blocking octanol, every 132g alcohol needs to use
250ml n-hexane washing extraction organic phase carrys out purified product, and solvent also needs to remove by vacuum distillation.
It can be seen that above-mentioned process for purification not only needs using a large amount of organic solvents, and product epoxy radicals may also be deposited
Destroy certain, and the usual molecular weight of polyethers product is big, boiling point high it is impossible to obtain the high color of purity simply by vacuum distillation
The good end-blocking product in pool.Patent CN104387576A discloses can be high by the one-step method acquisition low ending ratio of color and luster using NaH
The method of epoxy radicals end-blocking allyl alcohol polyether, but H can be produced using NaH2There is explosion danger, be not suitable for industrial production.
For general polyethers post processing, when using adsorbent adsorption bleaching, it is required to add the pH value to polyethers for the acid
It is adjusted so as to carry out refinement treatment under mildly acidic conditions, but to the sour more difficult control of accurate addition, can be to reality
Bring the inconvenience of operation in production, and to the polyethers with epoxy radicals end-blocking, acid also can make active epoxy bond that open loop occurs,
Thus affecting the ending ratio quality of product.
It is thus desirable to exploitation can obtain low color, epoxy bond be had the post processing process for refining of certain protection to obtain Gao Pin
Matter product, to meet the market demand with this.
Shortcoming in order to overcome above-mentioned prior art develop a kind of preparation of AEO glycidol ether and
Its post-processing approach, compares compared with technique, and the present invention prepares AEO glycidol using one-step method
Ether crude product, by adding polymerization inhibitor in end capping reaction, on the one hand can reduce and lead to product color by epoxychloropropane autohemagglutination
Too deep problem, on the other hand it is also possible to reduce being polymerized between autohemagglutination and product and the epoxychloropropane between product epoxy radicals
The yield being led to reduces and the high problem of product viscosity.By crude product after solids removed by filtration, using modified magnesium silicate and hydroxyl
Methyl sulfinic acid sodium mixture makes technological operation for adsorbent and decolorising agent it is not necessary to outer acid adding is adjusted to polyethers crude product pH value
Simply, and epoxy bond can also be played a protective role, by decolour post processing obtain color and luster be less than 60 (platinum-cobalt method), produce
The AEO glycidol ether that product ending ratio is more than 90%.
Based on this, make the application.
