Abstract: PROBLEM TO BE SOLVED: To reproducibly synthesize a MFI-type thin zeolite film with a size of a μm order. SOLUTION: A reaction solution with the following composition. SiO 2 : an organic amine : tetrapropyl ammonium bromide : H 2 O=1:x:y:z (wherein the compositional ratio is molar ratio; x=0.25-5; y=0.4-8; and z=100-300) is heated in a closed vessel at a temperature of ≥100°C and maintained for ≥1 hour. The MFI-type zeolite obtained by this method is applied on a substrate to be oriented, which is useful as the substrate in manufacturing a zeolite film. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing carbon nanotube efficiently and in large quantities. SOLUTION: The carbon nanotube can be manufactured efficiently and in large quantities by using the apparatus using a chemical vapor deposition method with a simple operation, where a carbon-containing compound and a solid catalyst retained on a conveying device are continuously supplied into a heating furnace and catalyzed in a temperature zone heated at 500-940°C in the furnace to form the carbon nanotube and the resulting carbon nanotube retained on the conveying device coming out through the furnace is continuously recovered.

Abstract: PROBLEM TO BE SOLVED: To efficiently produce the subject active substance without needing a complicated process by allowing a raw materials to come in contact with a catalyst using an inorganic membrane. SOLUTION: This optically active substance is produced by allowing a raw material to come in contact with a catalyst using an inorganic membrane capable of passing at least one kind of the raw materials and the optically active substance to be obtained. In the method of using the inorganic membrane, the reaction is carried out by using a membrane which does not pass a homogeneously dissolved asymmetric catalyst for synthesizing an optically active substance but passes the optically active substance, which is at least one kind of reaction products, and the asymmetric catalyst which is partly or wholly dissolved can be recovered after or during the reaction. The effective component (separation membrane) for the separation in the inorganic membrane is preferably a molecular sieve membrane. Examples of the molecular sieve include crystalline silicate, crystalline aluminosilicate and the like. Regarding the shape of the inorganic membrane, the separation membrane is preferably coated on a porous support having larger diameters of fine pores.

Abstract: PROBLEM TO BE SOLVED: To recover a homogeneous catalyst having high performance but difficult to be recovered by forming a membrane from an inorg. membrane through which the catalyst, part or all of which is dissolved in a liq., is not passed. SOLUTION: An inorg. membrane used for this catalytic separation membrane may be any inorg. membrane if a catalyst, part or all of which is dissolved in a liq., is not passed through the membrane. An org. membrane cannot be used because it has inferior resistance to org. compd. performance, is swollen with an org. solvent and also has inferior separation performance. Since the purpose is to separate the catalyst used for an org. reaction, the inorg. membrane excellent in org. chemical resistance and without being swollen with an org. solvent must be used. The catalyst separation mechanism may be based on either of a size, an affinity or an other method. Though the mechanism is not clear at this point of time, the separation is preferably carried out by the size. The material of the inorg. membrane is not particularly limited if the catalyst can be separated but a molecular sieve membrane is preferably used.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing trioxane useful as a raw material for producing a polyoxymethylene copolymer, in a high initial rate of production and without forming a byproduct by using a specific solid acid catalyst having a high mechanical strength. SOLUTION: This method for producing trioxane is to make a contact of (A) formaldehyde with (B) a solid acid catalyst of a polyorganosiloxane having a sulfonic acid group (preferably contains 0.01-10mmol/g amount of sulfonic acid) and containing a skeleton expressed by the formula (R is a functional group containing sulfonic group) e.g. at 70-150 deg.C. Further, since the component B is a solid, the reaction is carried out by using a flow type, and in such case the reaction is performed by using 1-1000g feeding amount of the aqueous solution of the component A based on 1g component B.

Abstract: PURPOSE:To obtain the title sol which has never been obtained conventionally by heating an aqueous suspension containing zirconium hydroxide to give an aqueous mixture containing crystallized zirconia, adding an acid to the aqueous mixture, peptizing the mixture and dehydrating the zirconia sol. CONSTITUTION:An aqueous suspension containing zirconium hydroxide is heated and maintained at >=80 deg.C until zirconia is sufficiently crystallized to give an aqueous mixture containing crystallized zirconia. Then the aqueous mixture is blended with an acid and zirconia is peptized to give sol of fine crystallized zirconia dispersed in an aqueous solvent. Then the acid is removed from the sol. Removal of the acid is not especially restricted and, for example, removal of low-boiling acid by heating, adjustment of pH>=5.0 with anion exchange resin, etc., may be cited as the removal of acid. Consequently, weakly acidic crystallized zirconia-based sol having pH of weak acidity, excellent dispersibility and dispersion stability is obtained.

Abstract: PURPOSE:To enable supply of strongly basic crystallized zirconia-based sol, by adjusting pH to >= a specific value. CONSTITUTION:This sol is basic crystallized zirconia-based sol at pH >=9 and is useful as a precision abradant. The sol is obtained by heating an aqueous suspension containing zirconium hydroxide at >=80 deg.C until degree of crystallization of formed zirconia reaches >=80% to give an aqueous suspension containing crystallized zirconia and adding a basic substance to the suspension. A nitrogen- containing basic compound or an alkaline (earth) metallic hydroxide is used as the basic substance added.
