Abstract
Przedmiotem zgłoszenia są ciecze jonowe oraz sposób ich otrzymywania, mające zastosowanie jako herbicydy. Ujawniono amoniowe ciecze jonowe z kationem N-[2-(2,3,4,6-tetra-O-acetylo-ß-D-glukopiranozyloksy)etylo]-N,N,N-alkilodimetyloamoniowym i anionem herbicydowym, o wzorze ogólnym 1, w którym R oznacza podstawnik prostołańcuchowy o długości łańcucha węglowego od jednego do szesnastu atomów węgla, oraz A oznacza anion (4-chloro-2-metylofenoksy)octanowy. Sposób ich otrzymywania polega na tym, że bromki N[2-(2,3,4,6-tetra-O-acetylo-ß-D-glukopiranozyloksy)etylo]-N,N,N-alkilodimetyloamoniowe rozpuszcza się w alkoholu alifatycznym o długości łańcucha węglowego od 1 do 4 atomów węgla lub ich mieszaninie, korzystnie w metanolu, miesza się w stosunku molowym od 0,8 : 1 do 1 : 1,2, korzystnie 1 : 1 z alkoholowym roztworem soli sodowej lub potasowej lub litowej lub amonowej kwasu (4-chloro-2-metylofenoksy)octowego o stężeniu co najmniej 1%, w temperaturze od 20 do 60°C, korzystnie 20°C, w czasie co najmniej 2 minut, następnie odsącza się wytrącony z alkoholu, lub ich mieszaniny nieorganiczny produkt uboczny, po czym rozpuszczalnik lub ich mieszaninę usuwa się.The subject of the application are ionic liquids and the method of their preparation, applicable as herbicides. Ammonium ionic liquids with an N- [2- (2,3,4,6-tetra-O-acetyl-ß-D-glucopyranosyloxy) ethyl] -N, N, N-alkyl dimethylammonium and herbicide anion of general formula 1 are disclosed wherein R is a straight chain substituent with a carbon chain length of one to sixteen carbon atoms, and A is (4-chloro-2-methylphenoxy) acetate anion. The method of their preparation consists in the fact that N [2- (2,3,4,6-tetra-O-acetyl-ß-D-glucopyranosyloxy) ethyl] -N, N, N-alkyl dimethylammonium bromides are dissolved in an aliphatic alcohol carbon chain lengths from 1 to 4 carbon atoms or a mixture thereof, preferably in methanol, are mixed in a molar ratio of 0.8: 1 to 1: 1.2, preferably 1: 1 with an alcoholic solution of sodium or potassium or lithium or ammonium salt (4-chloro-2-methylphenoxy) acetic acid at a concentration of at least 1%, at a temperature of 20 to 60 ° C, preferably 20 ° C, for at least 2 minutes, then the precipitated alcohol or inorganic mixtures are filtered off by-product, after which the solvent or mixture thereof is removed.
