New quaternary alkoxymethyl tebuconasol salts with 3,6-dichloro-2-methoxybenzoic anion, method for obtaining them and applications as the two-function plant protection agents

摘要

the subject of new quaternary ammonium salts are alkoksymetylotebukonazolu with anionem 3,6 - dichloro - 2 - metoksybenzoesanowym of general formula 1 in which r is an alkyl substituent containing from 3 to 18 carbon atoms.the way they receive is that in the first stage of the process alkoksymetylotebukonazolu quaternary chloride of the general formula (2) in which r denotes alkyl substituent containing from 3 to 18 carbon atoms undergo reaction with stechiometrycznu0105 quantity of sodium hydroxide or water orotlenku potassium in the polar organic solvent, preferably methanol,during the 5 - 30 minutes, preferably 15 minutes at a temperature of from 20 to 60u00b0c, advantageously in use, then the inorganic salts were decanted, and the resulting quaternary hydroxide contained in the filtrate alkoksymetylotebukonazolu neutralises in stechiometrycznu0105 acid quantity 3.6 - dichloro - 2 - metoksybenzoesowego in solution in a polar organic solvent, preferably methanol,then the solvent is removed by evaporation under reduced pressure and the resulting product is dried under reduced pressure at a temperature of from 40 to 80u00b0c, advantageously in 120 degrees, in time from 4 to 24 hours, preferably 8 hours. new quaternary ammonium salts alkoksymetylotebukonazolu may find application as a dual function plant protection products especially as fungicides and herbicides.
