摘要： PURPOSE: To obtain an aqueous solution of 8-hydroxyquinoline-copper by dissolving an acid in an aqueous solvent and dissolving 8-hydroxyquinoline-copper and an alkylquinolinium salt or an alkylisoquinolinium salt into the resultant solution. CONSTITUTION: 8-hydroxyquinoline-copper (abbreviated as 8HQ-Cu) is dissolved in an aqueous solution containing 2-30wt.% of at least one kind of water-soluble acid selected from an inorganic acid and an organic acid (e.g. hydrochloric acid or p-toluenesulfonic acid) and 0.1-10wt.% of an alkylquinolinium salt and an alkylisoquinolinium salt. The dissolving molar ratio of the water-soluble acid/8HQ-Cu is 4-40. Water or a mixed solvent of water and an organic solvent (e.g. an alcohol) is usable as the aqueous solvent. The aimed composition is prepared by mixing 8HQ-Cu having extremely low solubility in water can be prepared in the form of an aqueous solution having a concentration of as high as 2-14wt.% without requiring particular processing condition and equipment. By this process, any metal corrosion derived from an acidic aqueous solution is suppressed. The aimed composition is useful as an antiseptic for wood and a disinfectant for agriculture.

摘要： PURPOSE:To obtain the titled compound in high efficiency, by reacting a tar-based isoquinoline containing S compound as impurity with an acid to obtain a crystallizable salt, purifying the salt to a specific desulfurization degree e.g. by recrystallization and subjecting to the alkali decomposition to effect the desulfurization. CONSTITUTION:Tar base obtained from coal tar or liquefied coal oil, etc., by acid extraction process is fractioned to obtain a tar-based isoquinoline having a purity of >=90wt%. A neutral hydrocarbon solvent or a water-soluble organic solvent is added to the isoquinoline, the produced crystallizable salt is slurried and made to react with an aqueous solution of an acid, and after the completion of the reaction, water is separated and are moved from the system to precipitate the crystallizable salt of isoquinoline. The salt is purified by recrystallization and/or washing with an alcohol or its solution to attain a desulfurization degree of >=90% and then desulfurized by alkali decomposition to obtain purified isoquinoline. EFFECT:The S compounds which cannot be separated by distillation are removed at a highest degree. USE:Synthetic raw material for pharmaceuticals and agricultural chemicals, etc.
