  • Patent number: 5068404
    Abstract: There is disclosed a process for producing the alkali metal salts of N-phosphonomethylglycine which comprises heating to an elevated temperature an aqueous solution of a di- or tri-alkali metal salt of N-alkyl-N-phosphonomethylglycine. The N-alkyl substituent contains at least one hydrogen on the beta carbon atom.
    Type: Grant

  • Patent number: 4806687
    Abstract: Ortho-alkylanilines are prepared by catalytic hydrodesulfurization of ortho-aminobenzyl sulfides using a cobalt-molybdenum oxide catalyst. For example, 2-methyl-6-trifluoromethylaniline is prepared by catalytic hydrodesulfurization of 3-trifluoromethyl-2-aminobenzyl sulfides. The substituted anilines prepared by the method of this invention are useful as intermediates in the synthesis of compounds shown to have herbicidal activity.

  • Patent number: 4654429
    Abstract: A process for the preparation of a glyphosate product. An .alpha.-substituted N-phosphonomethylamino diacetic acid substrate is contacted in an aqueous medium with molecular oxygen in the presence of a catalyst for the oxidative cleavage of a substituent from the imino nitrogen of the substrate. Cleavage produces a glyphosate product, carbon dioxide, a higher aldehyde, or ketone. Novel intermediates and methods of preparation thereof are also disclosed.

  • Patent number: 4496765
    Abstract: This invention relates to a process for the preparation of 2-(methylthiomethyl)-6-(trifluoromethyl) aniline, [MTA], from ortho-aminobenzotrifluoride, (OABT), employing a single solvent transformation via a sulfilimine intermediate. A sulfilimine hydrochloride salt is prepared by the oxidative addition of dimethyl sulfide to OABT in the presence of N-chlorosuccinimide. Neutralization of the sulfilimine hydrochloride salt with aqueous sodium hydroxide followed by phase separation results in an organic phase containing free sulfilimine and an aqueous phase generally containing succinimide and/or sodium succinimide. In a preferred embodiment the phase separation is performed in such a manner to leave a catalytic amount of succinimide in the organic phase. The free sulfilimine catalytically rearranges at moderate temperatures in the presence of this succinimide catalyst to form MTA.

  • Patent number: 4404069
    Abstract: Various substituted ortho-alkyl anilines are prepared by electrolytic desulfurization of various benzyl sulfides, sulfoxides and sulfones, e.g. 2-methyl-6-trifluoromethylaniline is prepared from 2-amino-3-trifluoromethylbenzyl sulfides, sulfoxides and sulfones. The processes are conducted in concentrated aqueous quaternary ammonium hydroxide, as well as in aprotic media. The substituted anilines obtained are useful as intermediates for herbicide compounds.
