Abstract

Przedmiotem zgłoszenia są nowe amoniowe ciecze jonowe z kationem alkilo[2-(2-hydroksyetoksy)etylo]dimetyloamoniowym o wzorze ogólnym 1, w którym R oznacza podstawnik alkilowy prostołańcuchowy zawierający od czterech do szesnastu atomów węgla oraz anion 2-(2,4-dichlorofenoksy)propionianowy. Przedmiotem zgłoszenia jest także sposób ich otrzymywania, który polega na tym, że czwartorzędowy bromek alkilo[2-(2-hydroksyetoksy)etylo]dimetyloamoniowy 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 2-(2,4-dichlorofenoksy)propionowego w stosunku molowym czwartorzędowej soli amoniowej do soli kwasu od 1:0,8 do 1:1,1, korzystnie 1:1, w środowisku wodnym, po czym produkt reakcji wydziela się metodą ekstrakcji dwufazowej za pomocą rozpuszczalnika organicznego z grupy: chloroform albo octan etylu, albo dichlorometan, po czym oddziela się fazę organiczną, dalej usuwa się z niej rozpuszczalnik, a produkt suszy pod obniżonym ciśnieniem w temperaturze 45 - 55°C. Zgłoszenie zawiera też zastosowanie przedmiotowych nowych amoniowych cieczy jonowych, jako środki ochrony roślin.The subject of the application are new ammonium ionic liquids with an alkyl [2- (2-hydroxyethoxy) ethyl] dimethylammonium cation of general formula 1, wherein R is a straight chain alkyl substituent containing from four to sixteen carbon atoms and an 2- (2,4-dichlorophenoxy anion ) propionate. The subject of the application is also a method for their preparation, which consists in the fact that the quaternary alkyl [2- (2-hydroxyethoxy) ethyl] dimethylammonium bromide of general formula 2, wherein R is a straight chain alkyl substituent containing from four to sixteen carbon atoms, is subjected to anion exchange reaction with 2- (2,4-dichlorophenoxy) propionic acid sodium or potassium or lithium or ammonium salt in a molar ratio of quaternary ammonium salt to acid salt from 1: 0.8 to 1: 1.1, preferably 1: 1, in an aqueous environment, after which the reaction product is isolated by two-phase extraction using an organic solvent from the group: chloroform or ethyl acetate or dichloromethane, after which the organic phase is separated, the solvent is further removed and the product is dried under reduced pressure at 45 - 55 ° C. The application also contains the use of these new ammonium ionic liquids as plant protection products.
