These new naphthalene derivatives have a general formula: Wherein R represents mutually independent groups. In I: R1:-alkylenyl-C(O)NH-alkylenyl-R3, -alkylenyl-C(O)O—R4, R3:—COOH, —OH, —SH, —NH2, -alkyl-NH-alkyl-N-dithiocarbamate alkaline earth metal salts, R4: H, succinimidyl group, R2: —H,-alkyl. In II: R1: -alkyl, -alkylenyl-halide-alkylenyl-hydroxyl-alkylenyl-O-aryl, —O-alkylsulfonate alkylenyl, R2: -halide-alkylenyl-O-aryl, -alkylenyl-O-alkylsulfonate, -alkylenyl-halide-, —CH(O), —HC?C(CN)2, —HC?CHNO2, -alkylenyl-NH2, -alkylenyl-NH-alkyl, -alkylenyl-alkyl-N-dithiocarbamate alkaline salts. The terms “alkyl” and “alkylenyl” refer to linear or branched aliphatic chains, preferably from 1 to 4 carbon atoms and the term halide to fluorine, bromine or iodine.

Abstract: A catalyst composition, and olefin polymerization process using same, formed from a mixture of a non-aluminoxane aluminum compound, an inorganic oxide and a transition metal bidentate or tridentate complex in certain prescribed proportions. The composition can be formed in a single step or in-situ in the polymerization reaction zone. The resultant catalyst has high activity and is capable of producing high molecular weight olefin products without reactor fouling.

Abstract: Complexes of the formulae I a to d, where M is an element of groups 6 to 10 of the Periodic Table of the Elements, preferably Ni, can be used for the polymerization and copolymerization of olefins, for example in suspension polymerization processes, gas-phase polymerization processes, bulk polymerization processes and emulsion polymerization processes.

Abstract: The present invention relates to diimine transition metal compounds having aryl groups with one or more electron-attracting substituents, compositions containing diimine transition metal compounds having aryl groups with one or more electron-attracting substituents, which are useful as catalysts for the polymerization of olefins, such as ethene/propene or ethene/&agr;-olefin copolymerization.

Abstract: Pre-blended combinations and reaction products of at least one metallic dithiocarbamate and at least one metallic dithiophosphate provide the synergism of antiwear properties with friction-reducing properties for lubricants and greases.

Abstract: A process for producing molybdenum oxysulfide dithiocarbamate (MoDTC) by reacting [A] an aqueous solution or suspension prepared by reacting (a) a compound having hexavalent molybdenum, with (b) an alkali hydrogensulfide or an alkali sulfide, [B] a carbon disulfide, [C] a secondary amine and [D] a mineral acid, wherein [E] a reducing agent is added and reacted at any stage, and a lubricating oil composition containing the compound obtained according to said process. MoDTC can be efficiently produced in high yields by using a hexavalent molybdenum compound as a starting material, and the produced MoDTC has low corrosive action, excellent wear characteristics and excellent lubricating properties.

Abstract: Reduction of asphaltene precipitation in asphaltenic subterranean reservoirs treated with aqueous solutions of strong acid is achieved by utilizing novel dithiocarbamate compositions to sequester iron.

Abstract: A method is provided for stabilizing alkylenebisdithiocarbamates (EBDC) by mixing the EBDC with chloralhydrate to reduce the content of alkylenethiourea (ETU) in the EBDC. The chloralhydrate is preferably added in an amount of about 0.1 to 5 weight percent based upon the EBDC. The preferably liquid (e.g., aqueous or alcoholic) reaction mixture is then preferably dried under vacuum. The stabilized EBDC product contains chloralhydrate, mono- and/or bis-trichloroethylol-alkylenethioureas, and less than about 0.015 weight percent ETU.
