NEW IONIC PAIRS WITH (4-CHLORO-2-METHYLPHENOXY)ACETATE AND THEIR SYNTHESES

摘要

New ionic pairs contain (4-chloro-2-methylphenoxy)acetate anion of the general formula 1, in which K means ammonium cation of the formula 2 or 3 or 4 or 5 or 6, or pyridinium cation of the formula 7, or imidazolium cation of formula 8, or morpholinium cation of the formula 9, or piperidinium cation of the formula 10, or 8-hydroxyquinolinium cation of the formula 11, or pyrazolium cation of the formula 12, or 2-chloroethylmethylammonium cation of the formula 13, or pyrolidinium cation of the formula 14, where R means alkyl linear chain group containing 1 to 18 carbon atoms or mixture of linear alkyl chains from 1 to 20 carbon atoms (common names cocalkyl or hydrogenated tallowalkyl) or polyoxyethylene chain. New compounds are obtained in the exchange reaction between chloride or bromide salts of K cation of specified formula and (4-chloro-2-methylphenoxy)acetic acid in presence of sodium or potassium salts used at molar ratio 1 : (from 0.8 to 3) : (from 0.8 to 4) at temperature from 273 to 373K in aqueous medium or organic solvent, followed by product isolation.
