Abstract The decomposition of DBP was studied in the presence of DTS in an ethanolic homogeneous solution and with DTS intercalated in montmorillonite clay mineral as a heterogeneous reaction. The kinetic parameters obtained from the two systems were monitored and indicated that the homogeneous system follows second order reaction kinetics for DBP, whereas the heterogeneous one follows a three-halves order. The heterogeneous system was found to possess higher catalytic efficiency and the reaction was shown to take place within the internal surfaces of the clay mineral. This was attributed to the great surface area of the catalyst, Lewis and Brönsted acid sites and its great ability to sorb the polar organic species.
