Methylation of phenol over Degussa P25TiO(2)

Gandhe, A.R.; Fernandes, J.B. (Journal of Molecular Catalysis A-Chemical. 226(2); 2005; 171-177.)

Degussa P25 TiO2 was evaluated as a catalyst for vapour phase methylation of phenol. It gave an optimum conversion of 32 percent at 450 degrees C and formed predominantly the ortho-, para- and meta-cresols. The activity ...
TiO2: As a versatile catalyst for the ortho-selective methylation of phenol

Gandhe, A.R.; Fernandes, J.B.; Varma, S; Gupta, N.M. (Journal of Molecular Catalysis A-Chemical. 238(41641); 2005; 63-71.)

The investigation describes synthesis of active pure and mixed phase TiO2 catalysts by a TiCl3-urea-oxalic acid precursor method. Pure and mixed phase TiO2 catalysts could be obtained by varying the concentration of oxalic ...
A simple method to synthesize N-doped rutile titania with enhanced photocatalytic activity in sunlight

Gandhe, A.R.; Fernandes, J.B. (Journal of Solid State Chemistry. 178(9); 2005; 2953-2957.)

This study demonstrates a simple route for the synthesis of nanocrystalline N doped rutile titania by calcination of acidified TiCl3 in presence of urea. Urea was used as a source of nitrogen. The N doped rutile titania ...
Designing novel polymers for solid-state nuclear track detection (SSNTD), I: novel homo- and co-polymers with allyl diglycol carbonate from N-allyloxycarbonyl diethanolamine-bis(allylcarbonate)

Mascarenhas, A.A.A.; Tilve, S.G.; Nadkarni, V.S. (Designed Monomers and Polymers. 8(2); 2005; 177-186.)

A novel monomer, N-allyloxycarbonyl diethanolanline-bis(allylcarbonate), has been synthesized and cast-polymerized for the first time to obtain poly-[N-allyloxycarbonyl diethanolamine-bis(allylcarbonate)] (PNADAC), which ...
Selective synthesis of dibutylamine over Na-beta Zeolite catalyst

Kakodkar, S.B.; Naik, S.P.; Fernandes, J.B. (Bulletin of the Catalysis Society of India. 4; 2005; 101-108.)
Selective synthesis of N-doped mesoporous TiO2 phases having enhanced photocatalytic activity

Gandhe, A.R.; Naik, S.P.; Fernandes, J.B. (Microporous and Mesoporous Materials. 87(2); 2005; 103-109.)

This study demonstrates a simple route for synthesis of nanocrystalline N-doped titania by calcination of acidified TiCl3 in presence of urea and oxalic acid. While urea was used as a source of nitrogen, oxalic acid was ...
A simple method to synthesize N-doped rutile TiO2 showing high photocatalytic activity in sunlight

Fernandes, J.B.; Kakodkar, S.B.; Naik, S.P. (Bulletin of the Catalysis Society of India. 4; 2005; 131-134.)
Convenient synthesis of volatile Streptomyces lactones

Amonkar, C.P.; Tilve, S.G.; Parameswaran, P.S. (Synthesis-Stuttgart. (14); 2005; 2341-2344.)

A convenient three-step synthetic approach towards 3-alkyl-5-methyl-2[5H] furanones is described. The steps involved in the synthesis are domino primary alcohol oxidation-Wittig reaction, acid-catalysed lactonisation and ...
Piperazinium dichromate(VI)

Srinivasan, B.R.; Naik, A.R.; Naether, C.; Bensch, W. (Acta Crystallographica Section E-Structure Reports Online. 60; 2004; M1384-M1386.)

The structure of the title complex, (C4H12N2)[Cr2O7], consists of dichromate dianions which are connected to the cyclic organic piperazinium (pipH(2))(2+) dications via hydrogen bonding. There are two crystallographically ...
Electrical, magnetic and catalytic oxidation studies on LaMn(1-x)Co(x)O(3) system

Salker, A.V.; Vaz, T. (Indian Journal of Chemistry Section A-Inorganic Bio-Inorganic Physical Theoretical and Analytical Chemistry. 43(4); 2004; 710-714.)

Lanthanum manganates and cobaltates and their intermediate compositions LaMn(1-x)Co(x)O(3) (x = 0.0, 0.3, 0.5, 0.7 and 1.0) with a perovskite structure have been synthesized by co-precipitation precursor technique. These ...
