Abstract
Przedmiotem zgłoszenia jest 3,6-dichloro-2-metoksybenzoesan alkilobetainianu metylu, o wzorze ogólnym 1 gdzie: R oznacza podstawnik alkilowy prostołańcuchowy zawierający od czterech do szesnastu atomów węgla. Zgłoszenie obejmuje też sposób jego otrzymywania, który polega na tym, że czwartorzędowy chlorek alkilobetainianu metylu o wzorze ogólnym 2, w którym R oznacza podstawnik alkilowy prostołańcuchowy zawierający od czterech do szesnastu atomów węgla, poddaje się reakcji wymiany anionu z solą sodową lub potasową, lub litową, lub amonową kwasu 3,6-dichloro-2-metoksybenzoesowego w stosunku molowym czwartorzędowej soli amoniowej do soli kwasu od 1:0,9 do 1:1,1, korzystnie 1:1, w temperaturze co najmniej 20°C korzystnie 20-50°C, w środowisku wodnym lub w rozpuszczalniku organicznym z grupy: metanol, etanol, propanol, izopropanol, butanol, po czym z rozpuszczalnika organicznego odsącza się powstały nieorganiczny produkt uboczny, z przesączu odparowuje się rozpuszczalnik, a produkt reakcji suszy się. Przedmiotem zgłoszenia jest zastosowanie 3,6-dichloro-2-metoksybenzoesan alkilobetainian metylu jako herbicydu.The subject of the application is methyl 3,6-dichloro-2-methoxybenzoate methyl betetate, with the general formula 1 where: R is a straight chain alkyl substituent containing from four to sixteen carbon atoms. The application also includes a method for its preparation, which consists in the fact that the methyl quaternary methyl chloride chloride of general formula 2, in which R is a straight chain alkyl substituent containing from four to sixteen carbon atoms, is subjected to anion exchange reaction with sodium or potassium or lithium salt , or ammonium 3,6-dichloro-2-methoxybenzoic acid in a molar ratio of quaternary ammonium salt to acid salt from 1: 0.9 to 1: 1.1, preferably 1: 1, at a temperature of at least 20 ° C, preferably 20- 50 ° C, in an aqueous medium or in an organic solvent from the group: methanol, ethanol, propanol, isopropanol, butanol, then the organic inorganic by-product is filtered off from the organic solvent, the solvent is evaporated from the filtrate and the reaction product is dried. The subject of the application is the use of methyl 3,6-dichloro-2-methoxybenzoate as an herbicide.
