摘要:The present invention provides a process for in situ synthesis of dispersion of ZnO and TiO 2 nanoparticles in an oil medium, wherein the process comprises: (a) providing layered basic zinc hydroxide (LBZ) in an oil medium, containing a dispersant, (b) providing a titanium precursor in the oil medium to obtain a mixture, (c) hydrolyzing the mixture to obtain a suspension, and (d) decomposing the suspension to obtain a dispersion of mixture of ZnO and TiO 2 nanoparticles. The present invention also provides an oil dispersion comprising dispersant stabilized mixture of zinc oxide and titanium dioxide nanoparticles were synthesized through this process. The dispersion contains up to 2.5 Wt % metals loading balanced with dispersant and base oil or dispersant alone. Addition of this dispersion to oil of lubricating viscosity improves the anti-wear property and resulting a low SAPS formulation.

摘要:5,7-dimethyladamantane-1,3-dicarboxylic acid dialkyl esters of general formula (I), wherein R is C4 - C30 alkyl. Method for synthesis of said dialkyl esters consists in synthesising 5,7- dimethyladamantane-1,3-dicarboxylic acid chloride, alcoholising said chloride by aliphatic alcohol in a boiling benzene or toluene, removing a solvent and in purifying a target product. Method for synthesising 5,7-dimethyladamantane-1,3-dicarboxylic acid in the form of an intermediate product consists in synthesising perhydroacenaphthene by acenaphthene hydrogenation, isomerizating perhydroacenaphthene into 1,3-dimethyladamantane in the presence of AICI3, in synthesising 1,3-dimethyl-5,7-dibromoadamantane by two- stage bromation of 1,3-dimethyladamantane in such a way that a monobromoderivative thereof is obtained at the first stage, is subsequently converting it into 1,3-dimethyl-5,7-dibromoadamantane at the second stage and in carboxylating said compound by formic acid in the presence of 10-20% oleum.

权利人:EXXON CHEMICAL PATENTS INC
摘要:A method is provided for the direct synthesis by living cationic polymerization of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino, cyanato, thiocyanato or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or a tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.
