| titleOfInvention | Method for obtaining sodium or potassium salts of ortho carboxylic acids |
| abstract | Usage: as intermediate reagents, as well as in printing. The product is sodium or potassium salts of orthocarboxylic acids f-ly R-C (OM) (OM) 2, where R is aryl, furyl, R-CH-CH-, СНз () 2-, (СНе) -. M Na, K. Yield 78-94%, basic substance content 94-98%. Reagent 1: carboiopa acid f-ly R-COOH, where R is indicated. Reagent 2: NaOH or KOH in the form of granules. Reaction conditions: in an inert solvent, for example diethyl ether or benzene, or homologues thereof, at 35-70 ° C. with vigorous stirring of the alkali granules with a mechanical stirrer, with a molar ratio of alkali jarbonic acid; acid 4-5: 1 and a ratio of the volume of solvent to the mass of the reaction mixture 10-12: 1. 2 tab. |
