| titleOfInvention | Manufacturing method of barium carbonate |
| abstract | The present invention provides a method for producing fine barium carbonate having a specific surface area of more than 45 m 2 / g economically and with less environmental load. The present invention relates to a method for manufacturing barium carbonate, which is a method for manufacturing barium carbonate, and is characterized in that the manufacturing method is selected from the group consisting of barium hydroxide, barium chloride, barium nitrate, barium acetate, and barium oxide. At least one barium compound, comprising the steps of: (a) adding citric acid and / or a salt thereof; (b) reacting carbon dioxide and / or a carbonate compound; and (c) adding a multivariate represented by the following formula (1) At least one of a carboxylic acid, an anhydride thereof, or a salt thereof, HOOC-X- (COOH) n ・ ・ ・ ・ (1) (In the formula, X represents a divalent or trivalent linking group, and the linking group represents a saturated hydrocarbon group having 1 or 2 carbon atoms, an unsaturated hydrocarbon group having 2 carbon atoms, or a benzene ring derived group which may also have a hydroxyl group as a substituent. Group; n represents 1 or 2); with respect to 100 mole% of the barium atom in the barium compound, (a) the addition of citric acid and / or a salt thereof mole% A and (c) represented by formula (1) Mole% B added to at least one of the polycarboxylic acid, its anhydride, or its salt satisfies the following formulae (I) and (II), 6.0 ≦ A ＋ B ≦ 16 ... (I) 0.01 ≦ A / B ≦ 7.0 (II). |
