  • Solvent-free process for the preparation of ((pyridinyloxy)phenoxy) propionate derivatives
    Patent number: 5049675
    Abstract: A solvent-free process for the preparation of herbicidal 2-(4-(pyridinyl-2-oxy)phenoxy)propionate esters is disclosed. The process involves the coupling of a 2-fluoropyridine and an ester of 2-(4-hydroxyphenoxy)propionic acid in the presence of an anhydrous base and in the absence of an added solvent.

  • Preparation of chlorinated pyridines
    Patent number: 4256894
    Abstract: Symmetrical tetrachloropyridine, pentachloropyridine and poly-chloro derivatives of 2-chloro-6-(trichloromethyl)pyridine are prepared by reacting a chloro-substituted (trichloromethyl)pyridine in the liquid state with chlorine at temperatures of from at least about 160.degree. C. and in the presence of an amount of a catalyst effective to catalyze the reaction.

  • Electrolytic production of certain trichloropicolinic acids and/or 3,6-dichloropicolinic acid
    Patent number: 4217185
    Abstract: Electrolytic reduction of tetrachloro-2-picolinic acid in basic aqueous solution, at an activated silver cathode, yields the 3,4,6- and 3,5,6-trichloro-2-picolinic acids, which in turn may be further reduced to 3,6-dichloropicolinic acid, a highly active herbicide.
