Abstract

Application of Response Surface Methodology (RSM) in the modeling and optimization of the synthesis of alkyl polyglucosides (APG) is presented. Two different sets of alkyl polyglucoside from glucose (G) have been synthesized using an acid catalyst. Decanol (C10) and dodecanol (C12) are used as sources of fatty alcohol (FA), and the interactions effect of catalyst concentration, substrate molar ratio and reaction time on the density of APG is observed. The optimum density in decyl polyglucosides (APG-C10) synthesis was obtained at a catalyst concentration of 1.5 % (w/wG), a substrate ratio of 3 (mol FA/G) and a reaction time of 3 h. While in dodecyl polyglucosides (APG-C12) synthesis, optimum density was obtained at a catalyst concentration of 1 % (w/wG), substrate ratio of 2 (mol FA/G) and 13 h reaction time. The substrate ratio and reaction time are significant variables that influence the acquisition of APG density in both reactions. A quadratic polynomial model was fitted to the data with an R2 of more than 0.95. So that the model obtained can be said to be very significant.
