OXIDATION OF PHENOL IN AQUEOUS SOLUTION WITH COPPER OXIDE CATALYSTS SUPPORTED ON γ-Al2O3, PILLARED CLAY AND TiO2: COMPARISON OF THE PERFORMANCE AND COSTS ASSOCIATED WITH EACH CATALYST

Brazilian Journal of Chemical Engineering (2015)

Carlos Augusto de Moraes Pires Amelia Santos Elizabete Jordão

The Catalytic Wet Air Oxidation (CWAO) of phenol using copper oxide catalysts supported by γ-Al2O3, TiO2, and pillared clay was evaluated to identify which of these catalysts was the most appropriate for this reaction. The CuO/PILC, CuO/γ-Al2O3 and CuO/TiO2 catalysts were the most successful at removing phenol and resulted in more than 96% conversion. Among these catalysts, CuO/γ-Al2O3 produced the largest amount of CO2, the lowest amount of intermediate products and the lowest amount of copper leaching. These results showed that the CuO/γ-Al2O3catalyst was the best for the end of the reaction. However, the methods used in this study did not allow us to identify the most appropriate reaction time (or catalyst). An alternative approach for this problem was to quantify the costs for each reaction time. Using this approach, the CuO/γ-Al2O3 catalyst was the most economically favorable catalyst when it was used during the first hour of the reaction.

Synthesis of C₃ Benzo[1,2‐e:3,4‐e′:5,6‐e′′]tribenzo[l]acephenanthrylenes (“Crushed Fullerene” Derivatives) by Intramolecular Palladium‐Catalyzed Arylation

Abstract The C 60 polyarenes 4 , 5 , 18 a , and 18 b have been synthesized from truxene by triple alkylation at C5, C10, and C15 followed by a palladium‐catalyzed intramolecular arylation. The synthesis of “crushed fullerene” C 60 H 30 ( 2 ) is the most efficient reported to date and proceeds in 33 % overall yield.

Reactivity of ruthenium(II) complexes with 1-hydroxymethyl- or 1-benzyl-3,5-dimethylpyrazole and similar functionalized bipyrazoles. X-Ray crystal structure of carbonylchlorohydrido(3,5-dimethylpyrazole-N 2)-bis(triphenylphosphine)ruthenium(II)

Journal of the Chemical Society. Dalton transactions (1987)

Antonio Romero Α. Vegas Amelia Santos Ana M. Cuadro

The complexes [RuCl2(PPh3)3], [RuClH(PPh3)3], and [Ru(CO)ClH(PPh3)3] react with 1-hydroxymethyl-3,5-dimethylpyrazole to give in all cases carbonylchlorohydrido(3,5-dimethylpyrazole-N2)bis(triphenylphosphine)ruthenium(II)(1a) as product. The substitution of the 1-hydroxymethyl group by hydrogen in the pyrazole ring is characteristic of these reactions. Similar reactions take place with 1,1′-di( hydroxymethyl)-3,3′,5,5′-tetramethyl-4,4′-bipyrazole and -methylenedipyrazole to give binuclear bipyrazole-bridged complexes [{Ru(CO)ClH(PPh3)2}2(µ-L′)][L′= 3,3′,5,5′-tetramethyl-4,4′-bipyrazole or -methylenedipyrazole respectively]. No reaction occurs with 1 -benzyl-3,5-dimethylpyrazole nor with the corresponding 1,l′-dibenzylbipyrazole. We have determined the crystal structure of [Ru(CO)ClH(Hdmpz)(PPh3)2](Hdmpz = 3,5-dimethylpyrazole). It crystallizes in the space group P21n with a= 9.687(3), b= 16.244(6), c= 24.022(6)Å, β= 94.19(2)°, and Z= 4. Standard anisotropic least-squares refinement gave R= 0.060 for 3 920 observed reflections. The ruthenium atom is six-co-ordinated in a distorted octahedral geometry with the atom pairs (P,P), (Cl,H), and (C,N) in trans positions.
