| titleOfInvention | Chemical process for the extraction of 2-hydroxy pyridine derivatives, 2-hydroxyquinoline, and 2-hydroxybenzothiazole |
| abstract | The present invention relates to alkali metal fluorides, chlorides, bromide, hydroxides, sulfates, sulfites, cyanates, cyanides, thiocyanates, thiosulfates, sulfides, phosphates, hydrogen phosphates, carbonates, bicarbonates, borates, claws Latex, hypochlorite, perchlorate, nitrite, chromate, dichromate or permanganate or calcium chloride, bromide, nitrate, nitrite, chlorate, hyperchlorite, perchlorate, thiocyanate, thiosulfate, chromate, di An aqueous alkaline or neutral solution of an alkali metal salt or calcium salt in which chromate or permanganate is dissolved is contacted with a partially water-miscible organic solvent to form 2-hydroxypyridine or 2-hydroxyquinolinone or 2-hydroxybenzo. Thiazole Egg Extracting an aqueous solution of a carry metal or calcium salt into the solvent (while maintaining the aqueous and solvent phase separations) and then separating the solvent phase containing the alkali metal or calcium salt and water from the aqueous solution (solvent to water in a separate solvent phase). Ratio is 0.5: 1-10: 1w / w), an alkali metal or calcium salt of halo or haloalkyl substituted 2-hydroxypyridine or 2-hydroxyquinoline or 2-hydroxybenzothiazole is extracted from the aqueous solution It is about how to do it. |
