SALTS OF 3-(4-METHYLPHENYL)SULPHONYLPROPIONIC ACID, METHOD FOR PRODUCTION THEREOF AND USE AS GROWTH REGULATORS OF AGRICULTURAL PLANTS Russian patent published in 2025 - IPC C07C317/14 C07C317/24 A01N41/10 A01P21/00 

FIELD: chemistry.

SUBSTANCE: invention relates to salts of 3-(4-methylphenyl)sulfonylpropionic acid of formula (I), where (1) X⁺ = K⁺, (2) X⁺ = NH₄⁺, (3) X⁺ = (C₂H₅)₃HN⁺ and (4) X⁺ = OHCH₂CH₂H₃N⁺. Invention also relates to a method of producing salts of 3-(4-methylphenyl)sulfonylpropionic acid, which consists in two-step one-pot synthesis of 3-(4-methylphenyl)sulphonylpropionic acid by reduction of p-toluenesulphonyl chloride with sodium sulphite in the presence of alkali to sodium p-toluenesulphinate at temperature of 70 °C for 3 hours in an aqueous medium. Then the reaction mixture is cooled to temperature of 30-40 °C, reacting with acrylic acid in presence of acetic acid, reaction mixture is held at temperature of 20-25 °C for 3-5 hours in an aqueous medium, followed by neutralization with potassium hydroxide, 25% aqueous solution of ammonia, triethylamine and ethanolamine. Salts of 3-(4-methylphenyl)sulphonylpropionic acid are used in agriculture as plant growth regulators.

EFFECT: salts of 3-(4-methylphenyl)-sulphonylpropionic acid, a method for production thereof and use as plant growth regulators in agriculture.
