Description
technical field
The present invention relates to a kind of preparation method of cardanol polyoxyethylene ether, belong to the synthesis technical field of polyether compound in organic chemistry.
Background technology
Cardanol is a kind ofly from natural cashew nut shell oil, through modern technique, to refine and to form, contain a large amount of active single component phenol and a small amount of diphenol, can replace or Partial Replacement phenol for the manufacture of epoxy hardener, liquid phenolic resin, liquid or pulverous heat-reactive phenolic resin, purposes very extensively and environmental-protecting performance outstanding.Cardanol has the activity of petroleum phenol, and it is that monohydroxy phenols has a long hydrogeneous base carbochain above, to have wide material sources, the characteristics such as recyclability, hypotoxicity and biological degradability in position betwixt.With petroleum phenol, synthetic alkylphenol polyoxyethylene is difficult for decomposing under physical environment, can cause environmental pollution, in a lot of developed countries, is all the forbidding product.Cardanol replaces the synthetic cardanol polyoxyethylene ether class tensio-active agent of petroleum phenol, has the characteristics such as acid-and base-resisting, because biological degradability is good, is called as " green " tensio-active agent or biomass tensio-active agent.
the structure of cardanol is:

From the structure of cardanol, the meta-substituent R of cardanol is mainly the carbochain of 15 carbon, has the structure of saturated, monoene, diene and triolefin, and the position of ethylene linkage is respectively 8,11 and 14.Cardanol easily and O
2react, its unsaturated terminal chain is oxidized to superoxide.Cardanol and derivative thereof are under the naphthenic acid katalysis or through Overheating Treatment, and the side chain of himself is addition mutually also, i.e. polyaddition reaction.The phenolic hydroxyl group of cardanol easily is oxidised with air to quinones.As time goes on, the color of cardanol can deepen due to oxygenizement.
The synthetic of cardanol polyoxyethylene ether is to take cardanol as raw material, and the phenolic hydroxyl group on the cardanol phenyl ring reacts with ethyleneoxide addition under the effect of catalyzer, generates cardanol polyoxyethylene ether.In the process of synthetic cardanol polyoxyethylene ether, oxidizing reaction or polyreaction easily occur in cardanol, and unsaturated terminal chain is damaged, and two key protection rates are low, and the different mixtures that generate various ingredients of its destructiveness, affect its application performance.
The existing synthetic technology about cardanol polyoxyethylene ether, China Patent No. is: CN101941891, patent name is: a kind of method of synthetic cardanol polyoxyethylene ether, introduced a kind of method of synthetic cardanol polyoxyethylene ether, with cardanol and oxyethane, it is raw material, potassium hydroxide is catalyzer, adds the acetic acid neutralization after reaction.It is few that this method prepares the cardanol polyoxyethylene ether surfactant byproducts, and product color is good, the reaction conditions gentleness, and the prices of raw and semifnished materials are cheap, but do not mention the sfgd. of unsaturated terminal chain.
China Patent No. is: CN102206336B, and patent name is: a kind of saturated cardanol polyoxyethylene ether and preparation method thereof, introduced a kind of saturated cardanol polyoxyethylene ether and preparation method thereof, cardanol is first carried out to hydrogenation reaction; Filtration, distillation and oxyethane carry out addition reaction; Underpressure distillation after adjust pH, filtration; Perhaps cardanol is first carried out to addition reaction with oxyethane; Carry out hydrogenation reaction after adjust pH, filtration, underpressure distillation after filtering.This product does not have the unsaturated double-bond structure of mixing, and has surfactivity and it has stable use properties.But need hydrogenation reaction and pressure distillation, reactions steps is loaded down with trivial details, hydrogenation process will be used organic solvent, easily to environment.
Above two patents of invention are the smell problem of not mentioned cardanol polyoxyethylene ether all.
