Abstract: PROBLEM TO BE SOLVED: To prevent undesirable fusing of a dehydrated substance and to obtain an anhydride product by passing sodium sulfate having a specified water content through a device, continuously raising the temp. of the device from the entrance to the exit, and maintaining low pressure. SOLUTION: Sodium sulfide having 35 to 45% water content, especially 38 to 40% is carried by mixing and passing through a device. The temp. of the Na2 S hydrate supplied to the device (product temp.) is continuously increased in such a manner that the temp. is about 20 deg.C at the supply position of the solid and >180 deg.C at the exit of the solid. At the same time, low pressure as =90 min residential time in the drying device.

Abstract: PROBLEM TO BE SOLVED: To provide a stable dispersion which contains a more reduced amount of a cationic polymer comparing with that in the known prior art. SOLUTION: The stable water-based dispersion contains particles of silicon dioxide/mixed oxides obtained by flame hydrolysis which contains aluminum oxide or titanium dioxide as the mixed oxide component and has a BET surface area of 5-600 m 2 /g and also has a negative ζ potential, as well as a cationic polymer which is dissolved in an amount of less than 100,000 g/mole, and is characterized in that this dispersion has a positive ζ potential.

Abstract: PROBLEM TO BE SOLVED: To provide a method of producing an organosilane functionalized at 3-position in which an allyl compound (H2 C=CH-CH2 X) is allowed to react with a silane (R2 R3 R4 SiH) in the presence of a heterogeneous platinum catalyst under a pressure of 1-25 bars in the reaction column. SOLUTION: A stoichiometrically excessive amount of the silane reactant is fed into the reaction column filled with an allyl compound. The reaction column preferably comprises the reaction zone, the first separation zone above the reaction zone and the second separation zone below the reaction zone. The first reaction product goes out of the reaction zone and comes into the first separation zone and the second reaction product goes out of the reaction zone and comes into the second separation zone whereby the distillation occurs simultaneously together with the reaction in the reaction chamber.

Abstract: PROBLEM TO BE SOLVED: To provide an aqueous dispersion containing silica that is produced by a thermal decomposition method and advantageous when used in a chemical mechanical polishing(CMP) process. SOLUTION: This purpose is achieved by the aqueous dispersion containing silica that is produced by the thermal decomposition method using aerosol by which the silica is doped with alkali. Regarding the silica in the dispersion, an average particle diameter of its second particles is =0.7.

Abstract: PROBLEM TO BE SOLVED: To provide a method for bonding solids using covalent bond in relatively low temperature by bringing organosilicon compound unimolecular layers applied on the surface of two solids into contact with each other. SOLUTION: This method comprises applying unimolecular layers of an organosilicon compound of the formula (R is methyl, ethyl or propyl; X is 1, 2, 3 or 4; Y is 2-6) [preferably bis(alkoxysilylpropyl)disulfane] on the respective surfaces of two solids and, thereafter, bringing the solids into contact with each other so as to bond their almost smooth surface of the solids. The solids to be bonded preferably have hydrophilic surfaces. The compound of the formula is preferably used in gas phase and deposited on the surfaces so as to form the unimolecular layers. The compound of the formula is preferably used as a solution having >0-10 mol/L concentration. This method can be used for a composite structural material for microelectronics and micromechanics.

Abstract: In dispersions of mixed oxide particles containing silicon dioxide and cationic polymer, the amount of cationic polymer can be 25% decreased by doping the silicon dioxide with 0.25 wt.% aluminum oxide without affecting the positive surface charge on the particles. A stable aqueous dispersion contains flame-hydrolytically prepared mixed oxide particles containing silicon dioxide and aluminum oxide or titanium dioxide, with a BET (Brunauer Emmett Teller) surface area between 5 and 600 m2/g, which shows a negative zeta potential, and a dissolved cationic polymer of weight average mol. wt. less than 100,000 g/mole, the dispersion having a positive zeta potential. Independent claims are also included for the following: (1) a process for preparation of the dispersion involving predispersion and final dispersion, where before predispersion the cationic polymer is included in an aqueous medium or is added during dispersion, or the mixed oxide particles and cationic polymer are added alternately; (2) a brushing on paint for formation of an ink acceptance layer using the dispersion and at least one hydrophilic binder; (3) a process for preparation of the brushing on paint by addition of the dispersion to a solution of hydrophilic binder, optionally with addition of other additives, followed by dilution to the required ratio of mixed oxide and binder and the desired total solids content; (4) an ink take up medium using a brushing on paint; and (5) a method for preparation of the ink take up medium involving application of the brushing on paint to a carrier and drying.
