Solid super acid, alkali catalyst is an important part of the industrial catalyst, but also in recent years, the field of catalysis research hotspot. The catalysts having a higher alkali strength, good catalytic activity, relatively low catalyst temperature, easily, and a reaction system separation, can be regenerated and reused, non-corrosive and does not produce pollution, etc. caused by the chemical work at home and abroad 's attention; traditional solid super acid, alkali catalyst carrier mostly of TiO2 ZrO2, Al2O3 and other oxides, the surface area is small, the pore structure is not rich, irregular defects. To compensate for this deficiency, and to explore the mesoporous molecular sieve as a carrier, synthetic molecular sieve type solid super acid, alkali catalyst. Mesoporous molecular sieves with regular pore structure, large specific surface area, adjustable pore structure, good thermal stability and catalytic selectivity, catalytic and adsorption of macromolecular compounds opened up broad application. Combine the advantages of the fine pore structure of mesoporous molecular sieves and solid superacid Superacidity or solid super base super alkaline synthesis of both a solid super acid, alkali catalyst high acid strength or base strength, high catalytic activity, but also have a regular pore structure of the zeolite catalyst, the height of the catalytic selectivity of new molecular sieve type solid superacid, alkali catalyst, will effectively increase the activity and selectivity of the catalyst to lower catalytic reaction temperature, and is more conducive Industrial Catalysis Application. I to Al-MCM-41 mesoporous molecular sieve as the carrier, creatively solid super acid, the active component of the base catalyst supported on Mesoporous Silica and skeleton structure were successfully synthesized SO42-TiO2-SnO2-Al-MCM -41 solid molecular sieve super acid catalyst and 2Na O2-/Al-MCM-41, of the Molecular Sieve solid super base catalyst on the two catalysts in organic synthesis preliminary study. Chapter mesoporous molecular sieve in recent years, solid super acid, super solid base catalyst research progress review, summarizes the advantages and disadvantages of the conventional solid super acid, alkali catalyst, and traditional solid superacid The alkali catalyst defects this topic. The second chapter, the author on the basis of the original laboratory research, shorter SO42-/TiO2-Al-MCM-41 the presence of a catalyst in catalytic life, improved water sensitive to Al-MCM-41 zeolite as the carrier impregnation method were synthesized a superacid catalyst containing titanium and tin S042-/Ti02-Sn02-Al-MCM-41 Molecular Sieve solid. By means of XRD, FT-IR, SEM, TG-DTA, BET, NH3-TPD, acid strength of analytical testing, characterization of mesoporous structure and surface properties. The results showed that the preparation of the catalyst has a rich and structured mesoporous structure, specific surface area of ??500.03 m2 / g, acid strength H0 ≤ -16.04, is a molecular sieve type solid super acid catalyst. Chapter the newly prepared SO42-/TiO2-SnO2-Al-MCM-41 Molecular Sieve solid super acid catalyst used in the synthesis of the dioctyl phthalate esters, pentaerythritol double reduction anisaldehyde and rice bran oil esterification deacidification reaction, the catalyst exhibits excellent catalytic activity, optimized synthetic conditions, phthalic dioctylphthalate highest yield of up to 99.93%, pentaerythritol Diacetal anisaldehyde yield up to 90.5%, rice bran Koh by 23.70% of the raw materials is reduced to 3.88%. The catalyst to overcome the shortcomings of SO42-/TiO2-Al-MCM-41 catalyst, the catalytic effect is better than traditional solid super acid catalyst. The fourth chapter, the author of Al-MCM-41 zeolite as the carrier met with NaOH and metal Na reaction at higher temperatures, prepared a super base catalyst the 2Na O2-/Al-MCM-41 solid molecular sieve. The catalysts were characterized by XRD, FT-IR, BET, SEM, TEM, base strength and determination of the alkali concentration analysis test means, the results show that, compared to similar solid super base catalyst, the catalyst has good pore structure than a surface area of ??276.06 m2 / g, the alkali strength H_ ≥ 37, the surface of the alkali concentration of 6.2 mmol / L, belonging to Solid Superacid alkali series strongest basic catalyst. Chapter freshly prepared the 2Na O2-/Al.MCM.41 solid molecular sieve super base catalyst used in dibenzylideneacetone, celery ketone biodiesel synthesis, the catalyst showed excellent catalytic activity and good catalytic selectivity optimized synthesis conditions, dibenzylideneacetone yield up to 89.65% of celery ketone highest yield of up to 87.6%, of biodiesel yield up to 92.6%. The high catalytic efficiency of the catalytic process, and pollution-free, non-corrosive, with good prospects for industrial applications.
