Abstract: The present invention provides certain metal (e.g., Ca or Mg) ester salt derivatives capable of exhibiting friction modification, oxidation inhibition, and corrosion inhibition properties in power transmitting fluids such as automatic transmission fluids. These salts are derived from mono or diesters prepared by the reaction of an alkanol (e.g., thio-bis-ethanol) and a hydrocarbon substituted succinic acid or anhydride, such as octadecenyl succinic anhydride.

Abstract: The low temperature properties of a distillate petroleum fuel oil boiling in the range 120.degree. C. to 500.degree. C. and having a final boiling point above 370.degree.

Abstract: A process for improving the catalyst life of zeolites employed in the conversion of alcohols (e.g. methanol) and/or their ether derivatives (e.g. dimethyl ether) wherein a suitable zeolite is modified in a 2-stage procedure by providing a controlled low amount of a coke precursor deposit on the external surface of the zeolite, and then heating this treated zeolite in an inert gas at specifically controlled temperatures for a minimum time is disclosed. A process of employing this modified zeolite to produce lower olefins is also disclosed.

Abstract: Oil soluble viscosity index improving ethylene copolymers, such as copolymers of ethylene and propylene; and ethylene, propylene and diolefin; etc., are reacted or grafted with ethylenically unsaturated carboxylic acid moieties, preferably maleic anhydride moieties, and reacted with polyamines having two or more primary amine groups and a C.sub.22 to C.sub.28 olefin carboxylic acid component, preferably alkylene polyamine and alkenyl succinic anhydride, respectively. These reactions can permit the incorporation of varnish inhibition and dispersancy into the ethylene copolymer while inhibiting cross-linking with resulting viscosity increase, haze or gelling.

Abstract: A process for preparing a catalyst composition wherein a Metal Hydrocarboxide I, such as aluminum secbutoxide, a Metal Hydrocarboxide II, such as silicon ethoxide, an acidic phosphorus-oxygen composition, such as phosphoric acid, and water, are reacted in the presence of a liquid organic medium, such as acetone, to form a catalyst precursor composition, which is then calcined to form the catalyst, is disclosed.
