Appeal No. 95-4081
Application 08/071,895
dioctyldithiocarbamate, and barium heptylphenyl
dithiocarbamate; Group II metal phosphorodithioates such[8]
as zinc dicyclohexylphosphoro-dithioate, zinc
dioctylphosphorodithioate, barium di(heptylphenyl)-
phosphorodithioate, cadmium dinonylphosphorodithioate,
and the zinc salt of a phosphorodithioic acid produced by
the reaction of phosphorus pentasulfide with an equimolar
mixture of isopropyl alcohol and n-hexyl alcohol.
Many of the above-mentioned auxiliary extreme
pressure agents and corrosion-oxidation inhibitors also
serve as antiwear agents. Zinc
dialkylphosphorodithioates are a well known example.
14. Burjes differs from the subject matter of claim
26 in that it does not describe the presence of the borate
ester called for by paragraph (i) of claim 26.
Braid
15. Braid describes borate esters which are made by
reacting a hydroxy-containing organophosphorus compound,
having at least one sulfur atom with a boron compound. See,
e.g., Example 2 wherein boric acid [a boron compound] and O,O-
ditolyl-S-(2-hydroxypropyl)phosphorodithioate [a hydroxy-
containing organophosporous compound] is refluxed in benzene.
Zinc dioctyldithiocarbamate and barium heptylphenyl dithiocarbamate are8
dithiocarbamate containing compounds within the scope of paragraph (ii) of claim 26.
