The nitration of Chlorobenzene was carried out in presence of sulphated zirconia as catalyst at room temperature - 70 degrees C in CCl4 medium using stoichiometric quantity of nitric acid and acetic anhydride. The isolated ...

Vacuum filtration of clean coal slurries and flocculated slurries with cationic, anionic and nonionic surfactants has been investigated. Significant reductions in filter cake moisture content were obtained for all types ...

The role of surfactants (wetting agents) in effective and efficient flotation separation of naturally hydrophobic plastics, such as polyvinyl chloride (PVC) and polyacetal (POM) has been investigated in terms of wettability ...

In the present study the effects of organic additives like triethylbenzylammonium chloride (TEBACL), cetyltrimethylammonium bromide (CTABr) and tetrabutylammonium bromide (TBABr) on zinc electrowinning from acidic sulphate ...

Activation energies and the reaction kinetics for La(OH)(3) and La1-xGdx(OH)(3) powders synthesized by coprecipitation technique have been calculated from the differential thermal analysis patterns and compensation effect ...
