New ammonium ionic liquids, alkoxymethyl3-(methacryloylamino)propyldimetyl-ammonium 2,4-dichlorophenoxy)acetates, method for obtaining them and their application as herbicides

摘要

the subject of the invention are new ammonium ionic liquids (2,4-dichlorophenoxy) acetates alkoksymetylo [3 - (metakryloiloamino) propyl] dimethylammonium of general formula 1 in which r is alkyl substituent carbon chain length of from one to twenty two carbon atoms, and a oznac for anion (2,4-dichlorophenoxy) octanowy and how they receive applicable as herbicides.the way they receive is that quaternary chloride (alkoksymetylo) [3 - (metakryloiloamino) propyl] dimethylammonium undergo reaction of nitrate with sodium salt or potasowu0105, or lithium or ammonium acid (2,4-dichlorophenoxy acetic acid in a mole ratio of quaternary salts) 's to acid salts from 1: 0.9 to 1: 1.1, preferably 1: 1, at a temperature of at least 20u00b0c,in the organic solvent from the group of: methanol, ethanol, propanol, isopropanol, butanol, then with organic solvent odsu0105cza formed inorganic by-product of filtrate vaporized solvent, and the reaction product is dried.application of ionic liquids was also revealed new amoniowych containing cation (alkoksymetylo) [3 - (metakryloiloamino) propyl] dimethylammonium and anion (2,4-dichlorophenoxy) - octanowy as herbicides.
