Catalytic esterification via silica immobilized p-phenylenediamine and dithiooxamide solid catalysts

The p-phenylenediamine (PDA) and dithiooxamide (DTO) were immobilized onto silica from rice husk ash (RHA) using 3-chloropropyltriethoxyilane (CPTES) to form a solid catalyst denoted as RHAPDA and RHADTO, respectively. BET measurements of the catalysts showed the surface area to be 145 and 9.7 m2 g−...
