Abstract
Kinetics of the acid catalyzed glycosidation reaction has been investigated over a broad range of operating conditions. The effect of mass transfer, speed of agitation, catalyst loading, substrate concentration, and temperature on the reactions has been reported.
The effects of various solvents on the reaction have been investigated. A glycosidation reaction was found to be zero order with respect to the n-decanol concentration. The experimental
data could be fitted into the model involving a surface reaction controlling mechanism with dissociative adsorption of n-decanol and D-glucose for glycosylation reaction. The apparent activation energy for the catalytic glycosidation of D-glucose was found to be 36.75 kJ mol–1.
