Title: Production of epoxy resin
Inventor: NAKANE YUKARI
IPC: C08G59/06
Filed: 1988-12-26
Abstract: PURPOSE:To obtain an epoxy resin of a low hydrolyzable chlorine content in high yields at low energy by reacting a phenolic compound with epichlorohydrin in the presence of an alkali hydroxide while azeotropically distilling off the water formed in the reaction system together with part of the epichlorohydrin. CONSTITUTION:A monohydric or polyhydric phenol compound (e.g. bisphenol A) and epichlorohydrin are fed to a reaction zone 1 and uniformly dissolved. The solution is heated by feeding steam to the jacket while an aqueous solution of an alkali hydroxide (e.g. sodium hydroxide) is fed to it in small portions and reacted. The water formed in the reaction system is azeotropically distilled off with part of the epichlorohydrin and condensed by cooling with a condenser 2. The condensate is separated into two phases of a water phase and an organic phase in a water separation zone 3, and the water-containing organic phase is azeotropically dehydrated in an azeotropic dehydration zone 4, whole the separated organic phase is returned to the reaction zone 1 and further reacted to produce and epoxy resin.

Title: Heat storage type cold storage bin
Inventor: MASATOKI YOSHIBUMI
IPC: F25D16/00
Filed: 1988-12-23
Abstract: PURPOSE:To effectively use the space by significantly reducing the installation space and ensure the quality by maintaining the cold storage bin in a certain temperature range by keeping the coldness during the heat accumulation operation by means of opening and closing the temperature controller unit for the heat accumulation compartment. CONSTITUTION:A compressor 42 is operated to perform a heat accumulation, wherein the heat accumulation compartment 27 is cooled by a cooling unit 29 which has been cooled and the heat storage material 28 is cooled and frozen by the cold air in the heat accumulation compartment 27. When the temperature of the heat accumulation compartment temperature sensing part reaches the set temperature of approximately -20 deg.C past the completion of freezing of the storage material 28, a heat accumulation compartment temperature regulator 32 is started to cause the compressor 42 to repeat the start and stoppage so as to maintain the temperature of the heat accumulation compartment 27 within a certain temperature range. The cold storage bin 41 is cooled by the cold air in the heat accumulation compartment 27 which enters from an opening 35 and a vent 36 as well as through the heat insulating partition 34. As the heat accumulation compartment 27 is controlled in the constant set temperature range, the quantity of heat to cool the cold storage bin 41 becomes constant. Although the cold storage bin 41 releases heat to the atmosphere, it is balanced out to maintain the temperature at about 0 deg.C to 5 deg.C by the cooling effect by the heat accumulation compartment 27 and the atmosphere.

IPC: C01G1/00
Filed: 1987-12-25
Abstract: PURPOSE:To obtain a copper alkoxide soln. having uniform quality and high concn., and to enable production of a compound oxide of extremely high uniform quality in a synthesis of an oxide superconductor using a metal alkoxide, by using thereby a specified kind of alcohol. CONSTITUTION:An alkali metal alkoxide is synthesized by allowing an alcohol expressed by the general formula HO(CH2CH2O)nR to react with alkali metal. In the formula, R is H or 1-15C alkyl or aromatic group n is an integer 1-6, wherein a combined case where R is H and n is 1 is omitted. Then, a Cu salt is allowed to react with said alkali metal alkoxide. The synthetic reaction may be possible without adding any other solvent than alcohol, when alcohol is used in excess. Since a copper alkoxide soln. having high uniform quality and high concn. is obtd. by this method, a superconductor is produced by adding, for example, a Ba component and a Y component in the form of alkoxide to the soln. and causing hydrolysis.
