  • Methods of producing methyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylate
    Patent number: 8754110
    Abstract: Methods of producing methyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylate. One method comprises adding methyl isobutyl ketone to an aqueous solution comprising 4-chloro-2-fluoro-3-methoxyphenyl-boronic acid to form an organic phase comprising the 4-chloro-2-fluoro-3-methoxyphenylboronic acid and an aqueous phase. The organic phase and the aqueous phase are separated. The 4-chloro-2-fluoro-3-methoxyphenylboronic acid is reacted with methyl 4-(acetylamino)-3,6-dichloropyridine-2-carboxylate in methyl isobutyl ketone to produce methyl 4-(acetylamino)-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylate, which is deacetylated to produce methyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylate.

  • Process for the preparation of 1,1'-bi-2-naphthols
    Patent number: 4496773
    Abstract: The invention is a process for coupling 2-naphthols which comprises contacting 2-naphthols dissolved in a polar acidic solvent in the presence of a catalytic amount of a catalyst which comprises a readily reducible form of a Group IB, Group VIII or manganese metal in the further presence of oxygen or a source of oxygen, under conditions such that 1,1'-bi-2-naphthol is prepared.

  • Inhibitor for gas conditioning solutions
    Patent number: 4102804
    Abstract: The corrosion of iron and steel by an aqueous sour gas conditioning solution used to remove CO.sub.2 from a gas stream is effectively inhibited by a combination of a quaternary pyridinium salt and an organic thioamide, a water-soluble sulfide or a water-soluble thiocyanate.
    Type: Grant
    Filed: March 28, 1977
    Date of Patent: July 25, 1978
    Assignee: The Dow Chemical Company
    Inventors: Robert C. Clouse, Robert G. Asperger
  • Quaternary salt-polyamine inhibitor for sour gas conditioning solutions
    Patent number: 4100099
    Abstract: The corrosion of iron and steel by an aqueous sour gas conditioning solution used to remove CO.sub.2 and H.sub.2 S from a gas stream is effectively inhibited by a combination of a quaternary pyridinium salt and a lower alkylenepolyamine or corresponding polyalkylenepolyamine.
    Type: Grant
    Filed: March 28, 1977
    Date of Patent: July 11, 1978
    Assignee: The Dow Chemical Company
    Inventors: Robert G. Asperger, Robert C. Clouse
  • Cobalt-containing inhibitor for sour gas conditioning solutions
    Patent number: 4100100
    Abstract: The corrosion of iron and steel by an aqueous sour gas conditioning solution used to remove CO.sub.2 from a gas stream is effectively inhibited by a combination of a quaternary pyridinium salt and an organic thioamide or water-soluble thiocyanate. The addition of a small amount of a water-soluble cobalt salt to the inhibitor combination improves its effectiveness.
