Description
Technical Field
The invention relates to a catalyst, in particular to a supported catalyst and application of the supported catalyst in preparation of hydroxyalkyl acrylate.
Background
The hydroxyalkyl acrylate is an important chemical raw material, is a colorless and transparent liquid and has two functional groups of carbon-carbon double bond and hydroxyl. The product has active property and wide application range, and is mainly used for fiber processing, paint, light-cured resin, adhesive, paper processing, rubber industry and the like. The material has a certain representativeness in terms of the characteristics of the preparation process and the material. The hydroxyalkyl acrylate as the special acrylate has seven synthetic process routes: 1) The ring-opening reaction method is to introduce alkylene oxide into acrylic acid and react under the action of catalyst and inhibitor to produce hydroxyalkyl acrylate and small amount of side product directly. The ring-opening reaction method is reasonable from the economical point of view, and is a general method for preparing hydroxyalkyl acrylate at present. The method has the characteristics of quick reaction, low reaction temperature, less side reaction, particularly less polymerization reaction, high reaction yield up to about 95 percent, simple post-treatment, easy distillation to obtain high-purity products and suitability for large-scale production. The method has the disadvantages of strict requirements on production equipment and operation conditions and high technical level requirements. 2) The one-step method is that acrylic acid, chlorohydrin and sodium hydroxide solid are heated to react, and the reaction end point is determined by analyzing the content of sodium chloride by a silver nitrate method. When the reaction reaches a certain conversion rate, the reaction is stopped. After cooling, sodium chloride produced by the reaction and unreacted sodium acrylate were filtered off under reduced pressure using a Buchner funnel. Adding a certain amount of diethylene glycol and hydroquinone into the obtained reaction mother liquor, carrying out reduced pressure distillation to separate out excessive chlorohydrin, and collecting hydroxyalkyl acrylate fractions. The one-step process is fast but the conversion increases very slowly by the end and the polymer increases with time. The chlorohydrin is in excess to ensure completion of the reaction, but the reaction solution is too viscous, which makes the reaction and separation difficult. The temperature has large influence on the reaction, the temperature is increased, the reaction rate is accelerated, but under the condition of pressurization and temperature rise, the polymerization is easy to occur, and the industrialization is difficult. 3) The direct esterification method is a reversible reaction of bimolecular, and is carried out under the catalysis of acid, and commonly used catalysts are sulfuric acid, hydrochloric acid, sulfonic acid, tin salt, organic titanate, cation exchange resin and the like. In view of corrosion of equipment in industry, benzenesulfonic acid, p-toluenesulfonic acid or cation exchange resins are generally used as catalysts. The direct esterification method is slow in reaction at low temperature, and the reaction temperature is often increased to increase the reaction rate; however, the esterification yield is low in the esterification process, and the selectivity problem of the monoester and the diester exists. In the prior art, concentrated hydrochloric acid is used as a catalyst, benzene is used as a water-carrying agent to synthesize hydroxyethyl acrylate, and a reaction mixed solution is subjected to neutralization, filtration and reduced pressure distillation to obtain a product, wherein the yield is 64%. The 001X 7 strong acid type cation exchange resin is used as a catalyst for synthesizing hydroxyethyl acrylate in high-class Changyan in China, the conversion rate reaches over 90 percent, the yield reaches 78.2 percent, and the purity reaches 98.1 percent. 4) The ester exchange method is that dihydric alcohol and methyl acrylate are subjected to ester exchange reaction, the ester exchange is generally carried out by methyl (ethyl) acrylate and the dihydric alcohol, and commonly used catalysts are strong bases such as sodium alkoxide, magnesium alkoxide, sodium hydroxide, calcium hydroxide, tetramethylammonium hydroxide and hexadecyltrimethylammonium hydroxide and strong acids such as concentrated sulfuric acid and sulfonic acid. In 1984, a czech researcher adopts tetramethylammonium hydroxide as a catalyst to obtain high-purity hydroxyethyl methacrylate only containing 0.1-0.3 percent of ethylene glycol dimethacrylate. Cheap methyl methacrylate reacts with ethylene glycol at home, hydroquinone is used as a polymerization inhibitor under the catalysis of hexadecyl trimethyl ammonium hydroxide to synthesize the hydroxyethyl methacrylate, and the yield is 92.3 percent. 5) The acyl chloride esterification method is characterized in that dihydric alcohol reacts with acryloyl chloride, and the acyl chloride and alcohol are subjected to esterification reaction in the presence of an acid remover (such as sodium ethoxide, sodium carbonate, pyridine, triethylamine, picoline and other alkaline substances) to generate ester. This is an irreversible reaction, the esterification of the acid chloride proceeds very easily and the acylation ability is stronger than that of the corresponding acid anhydride. The esterification of acyl chloride in the acyl chloride esterification method has the following advantages: (1) the byproduct generated in the acyl chloride reaction is hydrogen chloride gas which is easy to remove; (2) the acyl chloride has strong reactivity, high reaction rate and lower reaction temperature; (3) HCl generated in the esterification reaction can be removed with an acid remover to generate insoluble ammonium salt, so that the reaction is complete and the yield is high. However, the cost of acid chlorides is much higher than that of the corresponding carboxylic acids, and thus, the industrial application thereof is very limited. 6) Under the catalysis of alkaline resin and the protection of nitrogen, dihydric alcohol carbonate reacts with acrylic acid to prepare hydroxyalkyl acrylate. The advantage of the reaction of the glycol carbonate with acrylic acid is that the carbon dioxide formed in the reaction is easily removed. The disadvantages are long reaction time, high reaction temperature, easy generation of side reaction and low yield. 7) The chlorohydrin process is the reaction of a carboxylic acid salt with an active halide (or benzylic halide) to form an ester. Acrylic acid is first converted to sodium acrylate which is then reacted with chlorohydrin to form the hydroxyalkyl acrylate. The chlorohydrin method has the advantages of rapid reaction, mild conditions and safe production process. However, since the inorganic salt is precipitated during the reaction, the operation and the post-treatment are troublesome.
In the research of hydroxyalkyl acrylate catalysts, the catalysts used at home and abroad at present can be roughly classified into chromium-based, iron-based, copper-based, cobalt-based organic amines and the like, the chromium-based catalysts have high activity and high selectivity, but the catalysts are difficult to prepare, need to be matched with special auxiliaries and polymerization inhibitors, chromium is heavy metal, and chromium in refined residual liquid is difficult to recover and treat, so that the pollution to the environment is large. Iron series, copper series, cobalt series and organic amine catalysts are environment-friendly catalysts and belong to clean production technology. However, cobalt-based catalysts are limited by the source of raw materials and are difficult to scale up; the iron-based and copper-based catalysts have short service life and high production cost, and are required to be further researched.
The carbon-silicon material is considered to be a good carrier, has good hydrothermal stability, large specific surface area and rich pore structure, and is easy to load metal by a simple method. Modification of carbon materials can significantly change the valence electron cloud of the carbon materials, increase defect sites, increase the adsorption capacity of reactants, and the like, which may be beneficial to the progress of catalytic reactions or change product distribution, and the like. Therefore, the method for preparing the metal carbon-based heterogeneous catalyst with high activity, high stability and long service life by using the acrylic acid and the alkylene oxide as raw materials to carry out condensation reaction and using the carbon-silicon material as a simple carrier to be compounded with the metal simple substance and the compound thereof is a good development direction in the field of catalysis.
