Correlation between surface properties and catalytic activity of clay catalysts

Pushpaletha, P; Rugmini Sukumar; Lalithambika, M (Elsevier Science, 2005)

Surface properties always have a strong hearing on catalytic activity. Modification using mineral acids results in the variation of properties like acidity, cation exchange capacity, Surface area and porosity of a clay ...
A facile 1,2 proton migration of chalcone epoxide using acid activated palygorskites

Beena Joy; Ghosh, S K; Padmaja, P; Lalithambika, M (Elsevier, 2005)

Different natural as well as modified palygorskite clays, Padappakkara blue (Kaolinite) and Zeolite 4A have been used to study the rearrangement of chalcone epoxide. Acid washed palygorskite clays have been identified as ...
