Description
Technical Field
The invention belongs to the technical field of fine chemical synthesis, and particularly relates to bis-hydroxyethyl bisphenol A ether and a preparation method thereof.
Background
The bis-hydroxyethyl bisphenol A ether is mainly used as a structural unit of polyurethane, polyester and epoxy resin, and can be esterified with unsaturated acids such as acrylic acid, methacrylic acid and the like to prepare various functional high-molecular polymerization monomers. The elastic resin synthesized by condensation of bis-hydroxyethyl bisphenol A ether and aromatic dicarboxylic acid can isolate noise and reduce harmful vibration. The bis-hydroxyethyl bisphenol A ether is bonded into a high molecular polymer chain according to a certain proportion, so that the polymer has better strength, elasticity, adhesive force and processability. The bis-hydroxyethyl bisphenol A ether is mainly applied to the fields of paint, coating, printing ink, composite material, adhesive and the like.
At present, the research reports on bis-hydroxyethyl bisphenol A ether at home and abroad are more, most of the research reports are preparation methods of bisphenol A ether, and a small amount of patents are related to refining methods of bisphenol A ether. Such as:
chinese patent CN104203568B discloses an alkoxylated material with low bisphenol a residue, its preparation and use, wherein an alkali catalyst or an alkali metal catalyst is used as a catalyst, and molten BPA is used as a raw material for reaction. Because the melting point of the bisphenol A is about 158 ℃, the heating medium of the bisphenol A must be at least higher than 10 ℃ to melt the bisphenol A, and the melted bisphenol A is easy to have isomerization and decomposition reactions above 158 ℃, so that the by-products of the ethoxylation products of the bisphenol A are increased, and the color and luster of the products are difficult to ensure at high temperature.
Japanese patent JP 2011037792A discloses a process for producing a high-purity dihydroxyethyl ether of bisphenol by using water, toluene and xylene solvents for the production of the dihydroxyethyl ether. Alkali metal hydroxide, alkaline earth metal hydroxide, amine, quaternary ammonium salt and the like are used as catalysts. The preferred water solvent is water which can produce byproducts such as polyethylene glycol and the like under the action of an alkali metal hydroxide catalyst. Furthermore, amine catalysts tend to produce yellow color and produce amine ethoxylates as by-products. The bis-hydroxyethyl bisphenol A ether has high viscosity and is difficult to remove when the solvent water is removed. The toluene and the xylene can bring about complicated production procedures and environmental protection problems.
Chinese patent CN107216453A discloses a method for preparing bis-hydroxyethyl bisphenol A ether, which comprises the steps of reacting bisphenol A with ethylene oxide, and reacting at 120-150 ℃ by using KOH as a catalyst. Although the process can obtain high-purity bis-hydroxyethyl bisphenol A ether with low water content, the color is poor and is generally light yellow due to the alkali catalyst.
Japanese patent JP2008143854A discloses a method and a composition for preparing dioxy vinyl ether of bisphenol, which uses trialkylamine as a catalyst, lithium hydroxide and other amines as catalysts, and toluene as a solvent to synthesize a bisphenol A adduct at a temperature of 80-150 ℃. Although the synthesis method disclosed by the patent can obtain hydroxyethylated bisphenol A with the purity of 97.8%, the catalyst residue can influence the color of the product and deepen the color of the product by using the alkylamine catalyst, and the catalyst is not removed, so that the downstream application is influenced. The adopted solvents such as toluene and the like bring the problems of complicated production process and environmental protection.
US6342641 discloses a purified bisphenol a ethoxylate and a process for its purification by neutralization with a mineral acid, i.e. phosphoric acid, followed by treatment with a colloidal metal silicate. Because the direct neutralization method is adopted, the generated crystals are very fine and are difficult to be absorbed by magnesium silicate and other adsorbents, and the defects of difficult filtration, large product residual quantity in filter residues, high metal ion residue in products and the like are caused due to the high viscosity of the ethoxylated bisphenol A ether.
The synthesis of the technical scheme for preparing bis-hydroxyethyl bisphenol A ether disclosed at present mainly has the following three defects:
firstly, the melting point of bisphenol A is about 158 ℃, and two methods are generally adopted: the method is a high-temperature melting method (at least requiring high-temperature melting above 160 ℃), which can cause the color and luster of the product to be dark, and can easily cause the side reaction of bisphenol A under the high-temperature condition at high temperature, so that the by-products are increased; the second method adopts a solvent dissolving method, but the method needs complicated solvent removing procedures to increase the production cost, and most solvents have toxicity and great influence on the environment.
Secondly, the distribution of the components of the product synthesized by the catalysts of alkali metal hydroxide, amine and the like is wide, the distribution of the components of the product is difficult to control, and the requirements of certain products with high quality and high performance, such as UV curing coating reactive diluent, can not be met.
The product has high viscosity and high melting point, the catalyst for removing alkali metal hydroxide and alkaline earth metal hydroxide by the conventional method is difficult to remove, the catalyst removal cost is high, and the product loss is large.

s100, raw material pretreatment: sequentially adding bisphenol A and a zinc-magnesium oxide catalyst into a first reaction kettle filled with nitrogen, and heating; and heating the first reaction kettle to heat the materials to 80-130 ℃, preferably to 110 ℃.
S200, solvent pretreatment: and (3) adding the bis-hydroxyethyl bisphenol A ether into a second reaction kettle to be heated (the temperature is raised to 100-180 ℃, preferably 130 ℃) by taking the bis-hydroxyethyl bisphenol A ether as a solvent, so as to melt and stir the bis-hydroxyethyl bisphenol A ether.
Step S300, mixing and dissolving: and putting the bisphenol A and the zinc-magnesium oxide catalyst in the first reaction kettle into a second reaction kettle which is subjected to the bis-hydroxyethyl bisphenol A ether pretreatment, and heating until the bisphenol A is completely dissolved.
Step S400, reaction: adding a phosphoric acid auxiliary agent into a second reaction kettle, beginning to input a small amount of ethylene oxide into the second reaction kettle, beginning to stably input the ethylene oxide when the temperature is raised to the reaction temperature (the reaction temperature is 110-180 ℃, preferably the reaction temperature is 140 ℃, and the pressure of the second reaction kettle is controlled within 0.4 MPa), and preserving the temperature after the ethylene oxide is completely input to continue to react until the pressure in the second reaction kettle is not reduced any more.
Step S500, degassing: after the heat preservation continuous reaction is finished, cooling and degassing the second reaction kettle (specifically, cooling to 110 ℃ and degassing for 30min), and then filtering the zinc-magnesium oxide catalyst (for example, filtering the zinc-magnesium oxide catalyst through a filter at the bottom end of the second reaction kettle) to obtain a finished product. In addition, a certain amount of bis-hydroxyethyl bisphenol A ether can be continuously left in the second reaction kettle for the next reaction to be used as a solvent.
The bis-hydroxyethyl bisphenol A ether is synthesized by taking bisphenol A as a raw material, zinc magnesium oxide as a catalyst, phosphoric acid as an auxiliary agent, the bis-hydroxyethyl bisphenol A ether as a solvent and ethylene oxide as a chain extender. Thus, the method thoroughly solves the problems of complicated production procedures and environment caused by the solvent by using the bis-hydroxyethyl bisphenol A ether as the solvent of the reaction material without removing the solvent, greatly reduces the reaction temperature by using the zinc-magnesium oxide with very high selectivity as the main catalyst and phosphoric acid as the auxiliary catalyst, properly reduces the generation of byproducts in reaction activity, and ensures that the prepared product has stable performance (specifically, because the zinc-magnesium oxide has small apparent alkalinity and the alkalinity is related to the alkalinity corresponding to divalent metal ions in the composition, the alkalinity can be adjusted by the proportion of zinc and aluminum to achieve the effect of catalyst activity, meanwhile, the acid-base center on the surface of the zinc-magnesium oxide is exposed by high-temperature roasting to show stronger acid-base property, and the catalytic performance on the surface of the zinc-magnesium oxide is adjusted by the phosphoric acid auxiliary agent, finally, after the zinc-magnesium oxide catalyst is filtered by the reaction kettle, no catalyst residue exists in a reaction product, and the zinc-magnesium oxide serving as a main catalyst can be recycled, so that the product purification cost is greatly saved. )
