Ionic liquids with a cation tetramethylene-1,4-bis (methyl di alkyl ammonium) and anions (4-chloro-2-methylphenoxy) acetate and 3,6-dichloro-2-methoxy benzoate, and the process for their preparation

摘要

the subject of the invention is bisamoniowe ion liquids with kationem tetrametyleno - 1,4-bis (alkilodimetyloamoniowym) and anionami (4 - chloro - 2 - metylofenoksy) octanowym and 3,6 - dichloro - 2 - metoksybenzoesanowym, formula 1, where r means alkyl substituent on the carbon chain length from one to twenty carbon atoms, applicable as herbicides.one of the solutions they receive is that dichlorides or dibromki or diwodorotlenki tetrametyleno - 1,4-bis (alkilodimetyloamoniowe) is dissolved in methanol, mixed with a methanol solution of sodium or potassium, or litowej, or ammonium acid (4 - chloro - 2 - metylofenoksy) oct this concentration of at least 1% methanolic solution and sodium or potassium, or litowej,or ammonium acid 3,6 - dichloro - 2 - metoksybenzoesowego concentration of at least 1% with the addition of acid salts (4 - chloro - 2 - metylofenoksy) acetic acid and salts of 3,6 - dichloro - 2 - metoksybenzoesowego is unimportant, in mole ratio of quaternary salt to salt bisamoniowej acid (4 - chloro - 2 - metylofenoksy) acetic acid salt to 3,6 - dichloro - 2 - metoksybenzoesowego from 1: 0.5: 1 to 1: 1.5: 1, at a temperature from 293 to 363 k, then odsu0105cza inorganic by-product, after which removes the solvent from the filtrate.
