摘要:A new method for preparing salts of metal cations and organic acids, especially divalent salts of alkaline earth metal ions from group II of the periodic system and carboxylic acids. The method comprising the use of a high temperature (about 90° or more) and, optionally. high pressure, in order to obtain a higher yield, purity and faster reaction speed than obtained with known synthesis methods. In particular, the present invention relates to the production of strontium salts of carboxylic acids. Novel strontium salts are also provided by the present method.

摘要:A novel process for producing 3-oxocarboxylic acid esters, which are useful as intermediates in the synthesis of ceramides to be used as a humectant, biodegradable polymers, drugs, etc., at a high purity and a high yield without requiring any troublesome procedure, is disclosed. The process comprises reacting an acetoacetic ester with a calcium compound, a barium compound or a strontium compound in the presence of an organic solvent at a temperature of 10 to 120 DEG C., further reacting the obtained product with a carboxylic acid chloride to thereby acylate it, and then adding thereto an alcohol in an amount 1 to 5 times by mol as much as the calcium compound, barium compound or strontium compound to thereby deacetylate the same.

摘要:There are provided a film of surface Nb-containing La-STO cubic crystal particles that is effective as, for example, a thermoelectric conversion material for use at low temperatures of around room temperature, and an art for producing this film. The production method includes preparing a mixed aqueous solution in which an La-containing compound, an Sr-containing compound, a six-fold coordinated Ti complex compound, and an amphiphilic compound are dissolved; growing cubic-form crystals formed of La-doped STO in the mixed aqueous solution by a hydrothermal synthesis method; obtaining surface Nb-containing La-STO cubic crystal particles by dissolving a niobium-containing compound in this mixed solution and heating; and forming a particle film in which the surface Nb-containing La-STO cubic crystal particles are bonded, by disposing the surface Nb-containing La-STO cubic crystal particles on a substrate and carrying out firing.
