Bis (ammonium) herbicidal ionic liquids with alkyldiyl-bis (dimethylalkyl ammonium) cations and method for producing them

摘要

the subject of the invention is diamoniowe herbicydowe ionic liquids with cations alkilodiylo - bis (dimetylalkilooamoniowymi) 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) or formula (3), and s method for manufacturing them. ionic liquids are used as plant protection products.the solution is also the way they receive, which is 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% acid, containing a source of anions : (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.
