Description

For the preparation method of olefin hydration reaction nano-pore fluoride resin acidic catalyst
Technical field
The present invention relates to catalyst preparation technical field, especially relate to a kind of preparation method for olefin hydration reaction nano-pore fluoride resin acidic catalyst.
Background technology
The course of reaction producing fatty alcohol by olefin hydration is an important chemical production technology, mainly comprise butylene hydration legal system sec-butyl alcohol (SBA) in actual industrial production, and propylene direct hydration becomes isopropyl alcohol (IPA) catalytic reaction technology.
In recent years, the expansion of MEK demand facilitates the production of sec-butyl alcohol.Produce sec-butyl alcohol by the n-butene in hybrid C 4, there is the features such as cheaper starting materials is easy to get.Economical comparision analysis display is carried out from the aspect such as production technology, three-protection design to indirect hydration method, direct hydration method, storng-acid cation exchange resin is that the butylene direct hydration legal system sec-butyl alcohol of catalyst has that catalyst activity is high, technological process is simple and direct, product is easily separated with catalyst, catalyst long service life, equipment corrosion are little, the productive rate advantages of higher of sec-butyl alcohol, is the preferred option of producing sec-butyl alcohol engineering design from now on.Germany just develops from early 1980s the new technology that storng-acid cation exchange resin is the direct hydration legal system sec-butyl alcohol of catalyst, within 1984, drives successfully on 60,000 t/a sec-butyl alcohol commercial plants, instead of butylene sulfuric acid indirect hydration method.Existing domesticly builtly have butylene hydration legal system sec-butyl alcohol (SBA) large production equipment more than ten to overlap.The key factor having a high catalytic activity for ion-exchange resin catalyst is that requirement resin catalyst possesses larger specific area and pore volume and resin acidic intensity.
Industrial direct hydration method take acidic resins as catalysts, carry out hydration reaction at high temperature under high pressure, butylene conversion per pass lower (5%-6%), the butene feedstock that non-hydration transforms in a large number need after high pressure conditions step-down, reaction cycle is carried out in recompression pressurization, and energy consumption is very high.
Sulfonated phenylethylene hydrogen form cation acidic resins have homogeneous acid strength, stronger acidity and good stability, at present replace sulfuric acid to be widely used in the various acid catalyzed reactions such as various esterification, etherificate, alkylation of phenol, olefin hydration as solid acid resin catalyst, have product postprocessing simple, little to equipment corrosion degree, be convenient to the advantages such as continuous prodution.Preparation and application about storng-acid cation exchange resin acidic catalyst have many disclosed patents.Such as, notification number is the preparation method that the Chinese invention patent of CN1389297A discloses a kind of macroporous cation exchange resin catalyst with high exchange capacity; Notification number is that the Chinese invention patent of CN1555924A discloses a kind of high-capacity resin Catalysts and its preparation method.But the pore volume of common styrene-divinylbenzene cationic ion-exchange resin itself and specific area is little, the sour amount of hole surface is less, cause its Reaction-diffusion terms as solid acid catalyst restricted, thus make its reactivity and selective lower in heterogeneous catalysis application.
Common cationic ion-exchange resin ethene and the crosslinked of divinylbenzene make pellet shapes polymer, through the sulfonic resin of sulfonation gained; As the catalyst of hydration reaction, its stability increases with the increase of divinylbenzene content, but on sulfonic resin, the hydrolysis of sulfonation group also increases thereupon.Not only hydrolysis makes sulfonic acid group run off, and affects catalyst activity, and the sour gas corrosion equipment discharged, and therefore its serviceability temperature limit is between 130-150 DEG C.In order to improve the resistant to hydrolysis performance of sulfonation group on sulfonic resin, US Patent No. 4269943 proposes a kind of carries out chlorination modified processing scheme to storng-acid cation exchange resin, effectively can improve resin heatproof stability and reactive applications temperature between 150-160 DEG C.People are to carrying out chlorination modified process to strong acid cation exchange resin catalyst, and be applied to (Lv Zhihui in butylene direct hydration legal system sec-butyl alcohol technique, " petrochemical industry ", 32nd volume the 2nd phase 153-355 page in 2004), although butylene conversion per pass can rise to 6%-8%, but the specific area of resin catalyst and pore volume are not enhanced, therefore not yet significantly can change the still lower problem of butylene conversion per pass.
In recent years, for resin catalyst specific area and pore volume and the lower deficiency of resin acidic intensity, people attempt the olefin hydration reaction super acidic catalyst of development of new.Chinese invention patent CN1128250A discloses a kind of catalyst for hydration of olefines and preparation method thereof, become in isopropyl alcohol (IPA) catalytic reaction for propylene direct hydration, although have good isopropyl alcohol (IPA) selectivity of product, but this catalyst propylene conversion per pass is lower, and there is the loss of active constituent facile hydrolysis, cause the problem of Long-Time Service less stable, constrain its industrial applications.German patent DE 19829747A1 discloses a kind of acidic catalyst of solid montmorillonite load phosphoric acid, for in ethene, propylene direct hydration catalytic reaction, although can use at high temperature under high pressure to improve this catalyst propylene conversion per pass, but still there is the problem that active constituent facile hydrolysis runs off, stability in use is poor.The Nafion perfluorinated sulfonic resin of Dupont company exploitation is the solid super-strong acid be prepared from by perfluorinated sulfonic acid ether and tetrafluoroethene copolymerization, is applicable to the direct alkylation catalytic reaction of iso-butane butylene.But the very low (0.02m of the surface area due to Nafion resin 2/ g), need be carried on porous material just has higher catalytic activity.(ShenW on the SBA-15 that Nafion is synthesized at trimethylethoxysilane by dip loading by researcher, GuaY, XuHL.AppliedCatalysisA:General, 2010,377:1 – 8.), obtain surface hydrophobic, acid stronger Organic-inorganic composite solid-acid material.Result shows, and under equal sour load capacity, its catalyzing iso-butane alkane and butene alkylated effect are better than carried heteropoly acid and molecular sieve catalyst.But Nafion resin and the preparation cost both mesoporous material all higher, and be easy in load preparation process block SBA-15 duct, also exist operation wayward, preparation poor repeatability shortcoming, limit the possibility of its industrial applications.Foreign patent JP11216363A2 proposes at pore volume 0.20-0.90ml/g; aperture 10-5; the acidic catalyst of 000nm inorganic carrier load perfluorinated sulfonic acid; for in alkene direct hydration catalytic reaction; although can use at high temperature under high pressure; to improve alkene conversion per pass, but still this catalyst also exists, and preparation cost is high, repeatability is poor, the problem of stability in use, constrains its large-scale industrial application.Chinese invention patent CN1167011A discloses the preparation method of high thermal stability sulfonic acid type cation exchange resin catalyst, and Chinese invention patent CN1569334A also discloses comparatively similar Thermostable strong acid cation resin Catalysts and its preparation method.The resistance to elevated temperatures of polystyrene highly acidic resin catalyst is improved by introducing the electron withdraw groups such as F, Cl, Br on phenyl ring, but resin catalyst specific area still lower (30-50m 2/ g), cause its reactivity lower, and easily fouling and inactivation is very fast.
In sum, the above-mentioned analysis to existing alkene direct hydration reaction technology and cation acid resin catalyst method is visible, and the subject matter of restriction resin solid acid catalyzed reaction performance is resin catalyst specific area still lower (30-50m at present 2/ g) and resin acidic intensity, cause that its reactivity is lower, reaction selectivity is poor.
