199-202<span style="mso-ansi-language: EN-US" lang="EN-US">Hydroisomerization of hexadecane and the products obtained from hydroprocessing of jatropha oil has been carried out over different silica-alumina supported Platinum catalysts for the reduction of pour point. Amorphous silica-alumina support is found to be suitable for the required conversion and selectivity. Optimum reaction conditions such as platinum loading, silica-alumina ratio and various reaction conditions have been determined. </span

Synthesis and antimicrobial activity of 2-(4-formyl-3-pyrazolyl)-3-phenylindoles

2410-2415Vilsmeier-Haack reagent (POCl3-DMF) on reaction with hydrazones 3a-i derived from 2-acetyl-3-phenylindoles 2a-c furnishes 2-(4-formyl-3-pyrazolyl)-3-phenylindoles 4a-i. The structures of these compounds have been established on the basis of their elemental analyses and spectral (IR, 1H NMR) data. All the pyrazole derivatives 4a-i and their azines 5a-i have been tested for their antimicrobial and antifungal activities

A simple method for the determination of dispersion of metal complexes on the alumina support

505-507An ammonia pulse method has been devised for the determination of dispersion of metal ions and complexes on the surface of alumina support based on the ease of formation of metal-ammonia complexes at low temperatures, rapid desorption of physisorbed ammonia at high temperature and its high solubility in water. The method has been tested for copper(II), cobalt(II) ions and Cu(bipyridyl) and chromium(bipyridyl) complexes adsorbed on neutral alumina. The method is found to be fairly accurate (0.5% deviation)

Catalytic Activity of o-Phenanthroline Complexes of Cu(II) & Co(II) Supported on Alumina Surface: Decomposition of Hydrogen Peroxide

Effect of metal dispersion on hydrodesulphurization activity of alumina-supported molybdenum catalysts

362-365A series of catalysts have been prepared by varying the molybdenum metal content from 4 to 16 wt%. Catalyst support has been characterized for surface area and pore size distribution. Prepared catalysts are characterized for temperature programmed reduction as well as by X-ray diffraction. All catalysts are studied for CO chemisorption after pre-sulfiding and the results compared with diesel desulphurization activity. Correlations have been developed between CO chemisorption and hydrodesulfurization activity
