Protic ammonium cation ionic liquids (3-hydroxypropyl)dimethyl-ammonium and anion the herbicide and the method for their preparation

摘要

the subject invention is protic ammonium ionic liquids with kationem (2-hydroxypropyl) dimetyloamoniowym and anionem herbicydowym, of general formula 1, applicable as compounds with herbicydowym and how they receive, in which, a - means anion (4 - chloro - 2 - metylofenoksy) octanowy or (2,4-dichlorophenoxy) octanowy, or 3.6 - dichloro - 2 - metoksybenzoesanowy.process to obtain a proton ion liquid with kationem (3-hydroxypropyl) dimetyloamoniowym and anionem herbicydowym is that hydrochloride (3-hydroxypropyl) dimethylamine, soluble in aliphatic alcohol of carbon chain length from one to four carbon atoms or their mixture, are mixed with alcoholic solution of (4 - chloro - 2 - metylofenoksy) acetic acid, or (2),4 - dichlorophenoxy) acetic acid, or 3.6 - dichloro - 2 - metoksybenzoesowego, at a concentration of at least 1% in mole ratio (3-hydroxypropyl) dimethylamine to organic acid from 1: 0.9 to 1: 1.1, at a temperature from 293 to 363k, then odsu0105cza to inorganic by-product, after which the filtrate at suwa solvent and the product of drought.
