  • US Patent:
    39755185, Aug 17, 1976
  • Filed:
    Apr 10, 1974
  • Appl. No.:
    5/459579
  • Inventors:
    Archibald Miller Hyson - Newark DE
  • Assignee:

  • International Classification:
    A01N 912
    A01N 920
  • US Classification:
    424173
  • Abstract:
    Ternary and quaternary solvent systems consisting essentially of 20% to 92% by weight cyclohexanone, 3% to 25% by weight lower alkanol, and at least 5% by weight water, wherein 0-65% of said cyclohexanone can be replaced by an equal quantity of cyclohexanol, such that when sufficient S-methyl N-[(methylcarbamoyl)oxy]thioacetimidate to create a 35% solution of said thioacetimidate is dissolved therein at 25. degree. C. , a single phase results, and single phase, liquid, water-soluble insecticidal concentrates of S-methyl N-[(methylcarbamoyl)oxy]thioacetimidate containing 15% to 35% by weight of said thioacetimidate in such a ternary or quaternary solvent system.
