Synthesis, characterization and catalytic activity of cobalt phthalocyanine t…
Abstract. Cobalt phthalocyanine tetrasulphonamide was synthesized by reacting cobalt phthalocyanine with chlorosulphonic acid at 130–135 oC followed by addition of thionyl chloride to convert free sulphonic acid to sulphonyl chloride and subsequently amidation with ammonia. It was isolated by acidifying the reaction mixture with hydrochloric acid followed by filtration. It was characteriz…

Catalytic properties of nano-sized ZSM-5 aggregates
Abstract. Nano-ZSM-5 (NZ) with well-defined porosity was synthesized by organic silica method. The material exhibited more than a twofold increase in pore volume when compared to the normal ZSM-5 (HZ). The increase in pore volume is observed in the entire range of the pores with diameter from 5A˚ to 1500A˚ . The order of increase in volume is macropores (>500A˚ ) > micropores (up to 20A�…

Acidity and catalytic activities of sulfated zirconia inside SBA-15
Abstract. SBA-15 containing various amount (10–50 wt.%) of highly dispersed ZrO2 is prepared using urea hydrolysis method. The sulfated zirconia (ZrO2) in SBA-15 catalysts were prepared using these materials. The materials were characterized by XRD, BET surface area, TEM, TGA, acidity measurements using in situ IR pyridine adsorption, sulfate content and catalytic activities were studied …
