Selection of PTSA Catalyst Concentration for the Synthesis Alkyl Polyglycosides from Fatty Alcohol (C16) and Glucose Syrup 85%
Abstract: Alkyl polyglycosides
(APG) is a non-ionic surfactant that is environmental friendly and used in the
formulations of several products such as herbicides, cosmetics, personal careproducts
and petroleum displacer. The aims of this research were to obtain the best concentration
of p-toluene sulfonic acid (PTSA) catalyst for the synthesis of APG from fattyalcohol
(C16) and glucose syrup (85%) and to determine the performance of APG
surfactant produced. The concentrations of PTSA catalyst used were 0.6; 0.9;
1.2; and 1.5% from the weight of glucose used. Results showed that catalyst concentration
had no significant effect on the density, pH, and foaming performance, but gave
significant effect on interfacial tension. It was also shown that catalyst
concentration of 0.6% was different significantly from that of 0.9; 1.2; and
1.5%. However, there were no differences among 0.9; 1.2; and 1.5%,
respectively.The best catalyst concentration was 1.2% which gave the
interfacial tension value of 4.5x10-2dynes/cm, pH of 7.9, density of 0.9839
gr/cm3, and height of foam of 2.3%.
