  • Patent number: 4266945
    Abstract: Molybdenum-containing compositions are prepared by the reaction of an acid of molybdenum or salt thereof, phenol or aldehyde condensation product therewith, and a primary or secondary amine. The preferred amines are diamines such as tallow-substituted trimethylene diamine and their formaldehyde condensation products.

  • Patent number: 4263150
    Abstract: The properties of salts of dialkylphosphorodithioic acids are improved by treating said salts or their acid precursors with phosphites, especially triaryl phosphites. This process reduces the tendency of the salts to stain and corrode metal parts, especially copper parts, when incorporated in lubricants and functional fluids. The process may also be used to treat mixed metal salts of dialkylphosphorodithioic and carboxylic acids.

  • Patent number: 4256594
    Abstract: Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto, which melts between about 30.degree. and about 150.degree. C., and which contains a minor amount of a phosphorus-containing composition which may be prepared by the reaction of an alkoxylated alkyl phenol with a phosphorus trihalide, or, in combination with water, with a triaryl phosphite. The former reaction also produces, as a by-product, the corresponding halide. The phosphorus-containing compositions are especially useful in combination with a chlorinated wax. The preferred lubricant bases for the metal working lubricants comprise esters or polymers of epoxides or episulfides.

The composition may be applied in liquid form and solidifies on cooling to ambient and normal storage temperatures. Prior to application, the composition is preferably heated to a temperature higher than its melting temperature for ease of flow and uniform dispersion thereof onto the metal.

  • Patent number: 4234435
    Abstract: Carboxylic acid acylating agents are derived from polyalkenes such as polybutenes, and a dibasic, carboxylic reactant such as maleic or fumaric acid or certain derivatives thereof. These acylating agents are characterized in that the polyalkenes from which they are derived have a Mn value of about 1300 to about 5000 and a Mw/Mn value of about 1.5 to about 4. The acylating agents are further characterized by the presence within their structure of at least 1.3 groups derived from the dibasic, carboxylic reactant for each equivalent weight of the groups derived from the polyalkene. The acylating agents can be reacted with a further reactant subject to being acylated such as polyethylene polyamines and polyols (e.g., pentaerythritol) to produce derivatives useful per se as lubricant additives or as intermediates to be subjected to post-treatment with various other chemical compounds and compositions, such as epoxides, to produce still other derivatives useful as lubricant additives.
