Bis (ammonium) herbicidal ionic liquids with 3.6-dioxooctamethylene-(1.8)-bis (dimethylalkyl ammonium) cations and method for obtaining them

摘要

the subject of the invention is diamoniowe herbicydowe ion liquids with kationem 3,6 - dioksooktametyleno - (1.8) - bis (dimetyloalkiloamoniowym) of general formula (1), where r is an alkyl substituent: length of coal from 1 to 16 carbon atoms, and - means anion herbicydowy of general formula (2).way to receive diamoniowych herbicydowych ionic liquids, characterised by the fact that diamoniowy hydroxide is dissolved in methanol, and then undergo reaction inerting in mole ratio of 1:1 solution at a concentration of at least 1%, containing acid or a source of : ($4 - chloro - 2 - metylofenoksy) acetate, or (2,4-dichlorophenoxy) acetate.or (4 - chloro - 2 - metylofenoksy) propionianowego, or 4 - (2,4-dichlorophenoxy) - butanianowego, or (2,4,5 - trichlorofenoksy) acetate, or 4 - (4 - chloro - 2 - metylofenoksy) butanianowego or 3,6 - dichloro - 2 - metoksybenzoesowego.
