Abstract:
PROBLEM TO BE SOLVED: To provide a production process of obtaining chlorohydrins by reacting an aliphatic hydrocarbon substituted with a plurality of hydroxy groups such as glycerin with a chlorinating agent by a novel catalyst other than a carboxylic acid, a carboxylic acid derivative, and a compound having a carboxylic acid structure. SOLUTION: The process for producing chlorohydrins comprises reacting an aliphatic hydrocarbon substituted with a plurality of hydroxy groups with a chlorinating agent in the presence of a solid catalyst. The water in the reaction system is preferably continuously removed. The solid catalyst can include an inorganic oxide, an inorganic halide, a strongly acidic organic compound, and a combination thereof. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a safe stress mitigator made from a naturally occurring material. SOLUTION: The stress mitigator comprises β-1,3-1,6-D-glucan described below, which is derived from microorganisms belonging to the genus Aureobasidium sp., and the 1 H NMR spectrum of its solution in a 1N sodium hydroxide heavy water solution as the solvent has two signals, i.e. about 4.7 ppm and about 4.5 ppm, and the viscosity of its aqueous solution is 200 cP(mPa s) or less at 30°C, pH5.0 and 0.5(w/v%) concentration.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for shaping the structure of a decorative layer in which by using a special mold with a difference in specular glossiness made between a projection and a recess in press shaping, the feeling of wood grain or marble grain is expressed by the difference in specular glossiness, and the unevenness of a geometrical pattern is recognized visually and eminently and a method for producing the decorative plate thereof. SOLUTION: In the method for shaping the structure of the decorative layer, two resin-impregnated sheets are hot-pressed with the mold (an upper mold 111 and a lower mold 112) having a difference in specular glossiness of at least 6 in an index based on JIS Z8741 between a recess P and a projection Q. The press shaping is carried out so that the difference in specular glossiness between the projection and the recess of a press-shaped article 4 is at least 80% of the difference in specular glossiness of the mold 1.

Abstract:
PROBLEM TO BE SOLVED: To provide a gas diffusion electrode which has solved a problem of a conventional gas diffusion electrode that PTFE contained therein is not sufficiently durable, and consequently that the electrode easily deteriorates when used in a severe condition. SOLUTION: The gas diffusion electrode uses a fluorine resin of which the average molecular weight is controlled to 6×10 6 to 2×10 7 , for its gas diffusion layer and its reaction layer. Thereby, produced gas diffusion electrode has the less number of terminal groups per weight and consequently less deteriorates due to an oxidizing agent. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing 2-methylglycidyl ester important as a synthetic intermediate for medicines and physiologically active substances, especially its optically active substance, in a high yield and economically. SOLUTION: The method for producing 2-methylglycidyl ester comprises letting a basic reagent such as sodium hydroxide, potassium hydroxide, etc., act on a 3-halogeno-2-methyl-1,2-propanediol, performing an intramolecular ring closure to give 2-methylglycidol and reacting 2-methylglycidol with an acylating agent such as acetic anhydride, propionic anhydride, butyric anhydride, etc., in the presence of a base.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently producing N-(2,3-epoxy-2-methylpropyl)phthalimide. SOLUTION: The production method has such characteristics that a 2-methyl-epihalohydrin is reacted in an organic solvent, such as an alcohol or an ether, in the presence of an alkali metal carbonate, an alkali metal hydrogen carbonate, or a specific quaternary ammonium salt to yield an N-(3-halogeno-2-hydroxy-2-methylpropyl)phthalimide, which is then subjected to ring closure reaction with an alkali metal alkoxide.
