The 20% loaded TPA on AT-GMB showed the highest catalytic activity. The conversions of different
alcohols into the corresponding esters decrease in the following order: n-butanolNsec-butanolNter-butanol.
The selectivities for the corresponding esters are nearly 100%. The catalysts were characterized by surface
area, thermal analysis, XRD and FTIR spectroscopy. The reusability study shows that the catalysts are stable
and active.
