The present invention details a process for producing a catalyst powder. The steps of the process include preparing catalyst slurry, drying, pyrolyzing, and calcining the catalyst slurry to obtain a calcined catalyst powder. The catalyst slurry comprises a catalyst, a liquid carrier, a templating agent, and a catalyst substrate. The catalyst slurry is dried to obtain a raw catalyst powder. The raw catalyst powder is heated in a first controlled atmosphere to obtain a pyrolyzed catalyst powder and the pyrolyzed catalyst powder is calcined in a second controlled atmosphere to obtain a calcined catalyst powder. A method of fabricating a catalyst surface and catalytic converter using the prepared catalyst powder is also illustrated.

High yields of ester-substituted diary carbonates such as bis-methyl salicyl carbonate were obtained by the condensation of methyl salicylate with phosgene in the presence of a phase transfer catalyst (PTC) in an interfacial reaction system in which the pH of the aqueous phase was greater than 9.3. Using the method of the present invention conversions of greater than 99% were obtained whereas under standard conditions using triethylamine as the catalyst conversions were limited to 70-75% of the methyl salicylate starting material even with a 20 mole % excess of added phosgene. The optimized conditions of the of the present invention use only a slight excess of phosgene and represent an attractive route for the manufacture of bis methyl salicyl carbonate and ester-substituted diaryl carbonates generally.

High molecular weight polycarbonates are prepared from hindered bisphenols in a reaction sequence involving conversion of the hindered bisphenol to the corresponding bischloroformate and subsequent treatment with an amine catalyst and aqueous base to effect polymerization by hydrolysis and condensation of the bischloroformate groups. Tertiary aliphatic and cycloaliphatic amine catalysts bearing at least one methyl group are found to be especially effective in promoting this polymerization reaction. Reaction rates and selectivities are shown to be superior to known methods employing tertiary amines lacking methyl groups attached to nitrogen, such as triethylamine. The inclusion of chain stoppers allows the preparation of well defined mixtures of polycarbonate oligomers from hindered bisphenols. Additionally, the methodology may be used to prepare symmetrical diaryl carbonates from hindered phenols.
