Abstract
Przedmiotem zgłoszenia są 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 alkilowy o długości łańcucha węglowego od jednego do szesnastu atomów węgla, oraz A oznacza anion (2,4-dichlorofenoksy)octanowy o wzorze ogólnym 2. Zgłoszenie dotyczy także sposobu otrzymywania cieczy jonowych z kationem N-[2-(2,3,4,6-tetra-O-acetylo-ß-D-glukopiranozyloksy)etylo]-N,N,N-alkilodimetyloamoniowym, o wzorze ogólnym 1, określonych zastrzeżeniem 1. Sposób polega na tym, że bromki N-[2-(2,3,4,6-tetra-O-acetylo-ß-D-glukopiranozyloksy)etylo]-N,N,N-alkilodimetyloamoniowe o wzorze ogólnym 3, w którym R oznacza podstawnik alkilowy o długości łańcucha węglowego od jednego do szesnastu atomów węgla 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 (2,4-dichlorofenoksy)octowego, o stężeniu co najmniej 1%, w temperaturze od 20 do 60°C, korzystnie 20°C, w czasie co najmniej 4 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 with the cation N- [2- (2,3,4,6-tetra-O-acetyl-ß-D-glucopyranosyloxy) ethyl] -N, N, N-alkyl dimethylammonium and herbicide anion of general formula The application of claim 1, wherein R is an alkyl substituent with a carbon chain length of one to sixteen carbon atoms, and A is a (2,4-dichlorophenoxy) acetate anion of general formula 2. The application also relates to a method for obtaining ionic liquids with an N- [2- (2,3,4,6-tetra-O-acetyl-ß-D-glucopyranosyloxy) ethyl] -N, N, N-alkyl dimethylammonium, of general formula 1, as defined by claim 1. The method consists in that N- bromides [2- (2,3,4,6-tetra-O-acetyl-ß-D-glucopyranosyloxy) ethyl] -N, N, N-alkyl dimethylammonium of general formula 3, wherein R is an alkyl substituent with a carbon chain length of one to sixteen carbon atoms are dissolved in an aliphatic alcohol with a carbon chain length of 1 to 4 carbon atoms, or a mixture thereof, preferably in methanol, m Is mixed in a molar ratio of 0.8: 1 to 1: 1.2, preferably 1: 1 with an alcoholic solution of sodium, potassium or lithium or ammonium (2,4-dichlorophenoxy) acetic acid, at a concentration of at least 1 %, at a temperature of 20 to 60 ° C, preferably 20 ° C, for at least 4 minutes, then the inorganic by-product precipitated from the alcohol or mixtures thereof is filtered off, after which the solvent or mixture is removed.
