    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. An optional but preferred ingredient in the reaction mixture is at least one oil-soluble dispersant. The molybdenum-containing compositions are useful as additives in lubricants and fuels, and are especially useful in lubricants when combined with compounds containing active sulfur.

    Abstract: A process for preparing a lower alkene polymer from a lower alkene feedstream, including the steps of: (A) contacting the lower alkene monomer with a catalyst system comprising boron trifluoride and at least one acid selected from the group consisting of sulfuric acid, sulfurous acid, phosphoric acids and strong acid resins and (B) polymerizing the lower alkene monomer in the presence of the catalyst system at a temperature of about -3 DEG C. to about -30 DEG C. thereby obtaining a lower alkene polymer having a molecular weight of about 250 to about 500.

    Abstract: This invention relates to a composition comprising at least one sulfurized overbased product made by contacting (A) at least one overbased product or (A') at least one boron-containing overbased product with (B) sulfur and/or at least one source of sulfur; said overbased product (A) or boron-containing overbased product (A') being made using at least one acidic material, with the proviso that when said acidic material is other than SO2 or a source of SO2 said overbased product (A) or boron-containing overbased product (A') is contacted with an effective amount of SO2 or a source of SO2 to displace at least part of said acidic material. In one embodiment the sulfurized overbased product is an overbased thiosulfate or a boron-containing overbased thiosulfate. In one embodiment, the sulfurized overbased product is made using the overbased product (A) and the composition further comprises at least one non-sulfurized boron-containing overbased product. The sulfurized overbased products are thermally stable and are useful as extreme pressure (EP) and/or anti-wear agents or antioxidants for use in lubricants, functional fluids and normally liquid fuels. The functional fluids can be oil-based, water-oil emulsions or water-based. The sulfurized overbased products are particularly suitable for use as EP and/or anti-wear agents for use in gear lubricants and cutting fluids. In one embodiment lubricating compositions are provided that pass both the L-37 High Torque Test and the L-42 High Speed Shock Test without the necessity of employing phosphorus and sulfurized olefin anti-wear systems in their formulation.
