Description
Technical field
The present invention relates to a kind of 1,1,1-three (4-hydroxybenzene) alkane, particularly 1,1, the preparation method of 1-three (4-hydroxybenzene) ethane.
Background technology
– three (4 – hydroxy phenyl) ethane (THPE) is the trifunctional phenolic compound, can be used as linking agent or the branching agent of multiple polymers (such as polycarbonate, Resins, epoxy, polyarylester, tamanori and coating etc.), also can be used as the intermediate of preparation oxidation inhibitor.In polymer architecture, introduce THPE and can improve a lot of key propertys, such as hardness, thermotolerance, solvent resistance and agglutinating value(of coal) etc., in hyperbranched polymer, introduce THPE, can expand its Application Areas.
In the prior art, THPE normally take 4 – hydroxy acetophenones and phenol as raw material under the hydrogenchloride condition, adopting trichloromethane, methylene dichloride and ethylene dichloride etc. is solvent, make, but this method reaction times is longer, and the by product content of bisphenol A is higher, and solvent loss is large, the yield of products therefrom is lower, and cost is higher.United States Patent (USP) 5,756,781 disclose " making phenol and 4-hydroxyacetophenone in the presence of the ion-exchange catalyst of significant quantity and the mercaptan as co-accelerator " reaction, can obtain being substantially free of 1 of various reaction impurities, 1,1 – three (4 – hydroxy phenyl) ethane.United States Patent (USP) 5,756,781 disclose " making phenol and 2; the 4-diacetylmethane is in the presence of the mercaptan compound as promotor of acidic conditions and significant quantity " reaction, this patent further specifies, " described acidic conditions can obtain by adding any acidic substance, especially relative volatility material such as hydrogenchloride; and usually, hydrogen chloride gas during reaction passes through mixture ".Except other shortcoming, the deficiency of the above the whole bag of tricks is, needs the quantity of the catalyzer that uses higher, and the volatile acid of use such as hydrogen chloride gas are corrosive, and solvent loss is large, and product yield is generally not high.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provide a kind of reaction times short, yield is high, cost is low 1,1, the preparation method of 1-three (4-hydroxybenzene) ethane.
For solving above technical problem, the present invention takes following technical scheme:
A kind of 1, the preparation method of 1,1-three (4-hydroxybenzene) ethane, it is with phenol, parahydroxyacet-ophenone and catalyzer acetic acid join in the reaction vessel, stirring is warming up to 65 ~ 75 ℃, pass into nitrogen, begin reaction, remove water, sampling analysis, reach more than 80% to the parahydroxyacet-ophenone transformation efficiency, finish reaction, add stirring solvent, be cooled to room temperature, suction filtration gets 1,1, the crude product of 1-three (4-hydroxybenzene) ethane, wherein, the molar ratio of phenol and parahydroxyacet-ophenone is 5 ~ 10:1, the weight that feeds intake of catalyzer acetic acid be parahydroxyacet-ophenone and phenol gross weight 0.1% ~ 1%.
Further, the molar ratio of phenol and parahydroxyacet-ophenone is preferably 6 ~ 8:1.
Preferably, the weight that feeds intake of catalyzer acetic acid be parahydroxyacet-ophenone and phenol gross weight 0.15% ~ 0.5%.More preferably, the weight that feeds intake of catalyzer acetic acid be parahydroxyacet-ophenone and phenol gross weight 0.15% ~ 0.25%.
According to a concrete aspect, described solvent is dimethylbenzene.
Further, described preparation method comprises that also 1-three (4-hydroxybenzene) crude product of ethane carries out the step of purifying to described 1,1.Purification process can be taked known means of purification.For example, crude product can be contacted 0.5 ~ 2 hour with the methanol-water mixtures that contains at least 20% volumes methanol.Perhaps, when needed, can further, crude product be refluxed in the mixture of the alcohol that comprises discoloring agent; At last, visually colourless 1,1 to be settled out with the optional water treatment that comprises discoloring agent, 1-three (4-hydroxybenzene) ethane.In addition, crude product can also adopt the binding substances crystallization technique to carry out purifying.
Preferably, reach 80% ~ 82% to the parahydroxyacet-ophenone transformation efficiency, finish reaction.Usually, begin to reach 80% to transformation efficiency from reaction, need about 12 hours approximately.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
The present invention does not use solvent in the reaction process of preparation target product, only adopt a small amount of acetic acid as catalyzer, just can obtain target product by high yield; In addition, preparation method's cycle of the present invention is short, and cost is lower.
