摘要:
The present invention is directed to a sheet-form environment purifying material comprising particles of metal and/or metal oxide consisting essentially of at least one member being selected from the group consisting of manganese, copper, zinc, iron, vanadium, nickel, titanium, palladium, platinum, manganese oxide, copper oxide, zinc oxide, iron oxide, vanadium oxide, nickel oxide, titanium oxide, palladium oxide, and platinum oxide, adsorbent particles consisting essentially of at least one member selected from the group consisting of activated carbon, zeolite, silica gel, sepiolite, activated alumina and activated clay, thermoplastic resin particles being selected from ultrahigh-molecular weight polyethylene, polyethylene, polycarbonate, polyamide acrylonitrile-butadiene-styrene resins, polyimide, polyvinyl chloride, cellulose acetate, polysulfone, polystyrene phthalate and polypropylene, and an air-permeable sheet of fibrous. The metal and/or metal oxide particles and the adsorbent particles are respectively bound to the thermoplastic resin particles while retaining their inherent surface areas and performances without being covered by the thermoplastic resin layers, and the thermoplastic resin particles are joined to the fibrous substrate. The present invention is also directed to a process for making the environment purifying material which comprises the steps of mixing all the particles and heating the mixture at a temperature not lower than the melting point of the thermoplastic resin and not higher than the thermal decomposition temperature thereof. The environment purifying material of the present invention is useful as deodorizers and harmful gas removers.

An optically active lactone compound is produced by using a Zr(salen) complex of the following formula (I) or its enantiomer as a catalyst and subjecting a cyclic ketone compound to a Baeyer-Villiger reaction with at least one oxidizer selected from hydrogen peroxide, aqueous hydrogen peroxide and urea-hydrogen peroxide adduct in a solvent: wherein Ar1 is an aryl group having a carbon number of 10 to 16 and Y is a phenoxy group or an alkoxy group having a carbon number of 1 to 10.
摘要:
This invention provides a heat transmitting pipe and a heat transmitting plate which are capable of greatly improving the heat transfer efficiency of a conventional finned heating pipe and a convention heating plate. Copper oxide powder is deposited in a vapor phase onto a cellular synthetic resin coated with an adhesive beforehand. Thereafter, a copper plate with the same metal powder deposited thereon is placed on one surface of the metal powder-bearing cellular synthetic resin and is brought into lightly pressed contact with the surface by a roll press or the like, to thereby form a laminated article. Subsequently, the cellular synthetic resin is burnt off in a combustion furnace, to thereby produce a cellular metal material of the copper oxide on the copper plate. Further, the cellular metal material is reduced and sintered in a reducing atmosphere such as that of a hydrogen reduction furnace, to thereby produce a cellular copper material which is provided with the copper plate on one surface thereof. The cellular copper material can be directly used as a material for working a heat transmitting plate in a heat exchanger.
摘要:
In a nanochannel thin film in which oxide layers have surfactant micelles therein, the presence of a target substance in a sample solution is detected with a luminescence intensity of a thin film provided by recognition of the target substance with a luminescent recognition reagent in the nanochannels. Upon focusing on a hydrophobic field provided by the presence of the surfactant in pores of a nanometer size, the novel development of a sensor function is enabled.
