Abstract

There are two methods to produce alkyl polyglucoside (APG) which are direct method and indirect method. In this research, APG synthesize with direct method that involves by directly reacting d-glucose with decanol with molar ratio variation of d-glucose:decanol are 1:10; 2:10; 4:10 and 6:10 (mol GL/mol C10) and HCl concentration as catalyst variation are 0,5; 1; 1,5 dan 2 (% based on weight of d-glucose) in 3 hours with temperature reaction is 95 0C. Next process is neutralizing with strong base (NaOH) until pH value is about 8-10 then the aqueous solutions are distillated with vacuum distillation. This research analyze density, yield and wavelength. Decyl polyglycoside synthetic optimum results best density value is 1,05 gr/mL in molar ratio of d-glucose:decanol 2:10 (mol GL/mol C10) and catalyst concentration 0,5%. Best yield in molar ratio of d-glucose:decanol 2:10 (mol GL/mol C10) and catalyst consentration 1,5% (% based on weight of d-glucose) with yield value is 84,09 %. Wavelength analysis of ether and OH linkage with Fourier Transform Infrared (FT-IR) spectroscopy detected ether (COC) linkage at wavenumber 1032,33 cm-1 and OH groups detected at wavenumber 3365,21 cm-1.
