Abstract

Przedmiotem wynalazku są alkoksymetylodi(2-hydroksyetylo)metyloamoniowe ciecze jonowe z anionem mleczanowym o wzorze ogólnym 1, w którym R oznacza łańcuch węglowy zawierający od 1 do 16 grup CH2 oraz sposób ich otrzymywania. Ciecze mają zastosowanie jako środki antyelektrostatyczne. Ujawniono również sposób otrzymywania alkoksydi(2-hydroksyetylo)metyloamoniowych cieczy jonowych z anionem mleczanowym polegający na tym, że czwartorzędową sól rozpuszcza się w alkoholu alifatycznym o długości łańcucha węglowego od jeden do czterech atomów węgla, lub ich mieszaninie, po czym poddaje się reakcji z solą sodową lub potasową kwasu mlekowego w stosunku molowym 1 : 1 do 1 : 2, w temperaturze od 20 do 50°C, w czasie co najmniej 5 minut, a wytrąconą nieorganiczną sól odsącza się pod zmniejszonym ciśnieniem, z kolei z otrzymanego przesączu odparowuje się rozpuszczalnik, następnie dodaje się bezwodnego acetonu w celu oczyszczenia produktu, dalej po odparowaniu acetonu pozostałość suszy się w warunkach obniżonego ciśnienia.The present invention relates to alkoxymethyl di (2-hydroxyethyl) methylammonium ionic liquids with a lactate anion of general formula 1, wherein R is a carbon chain containing from 1 to 16 CH2 groups and the method of their preparation. Liquids are used as antistatic agents. Also disclosed is a method for obtaining alkoxydi (2-hydroxyethyl) methylammonium ionic liquids with a lactate anion in that a quaternary salt dissolves in an aliphatic alcohol with a carbon chain length of one to four carbon atoms, or a mixture thereof, and then reacts with the salt sodium or potassium lactic acid in a molar ratio of 1: 1 to 1: 2, at a temperature of 20 to 50 ° C, for at least 5 minutes, and the precipitated inorganic salt is filtered off with suction, and the filtrate is evaporated , then anhydrous acetone is added to purify the product, further after evaporation of the acetone, the residue is dried under reduced pressure.
