POo was epoxidised by using performic acid (HCOOOH) generated in situ to give EPO. EPO was hydrolysed with distilled water to give polyol -PO with 70 % yield. Both maximum oxirane cleavages recorded through continuous and batch hydrolysis method were catalysed by p erchloric acid 3 % v/wt at 60 minutes. Fourier transformation infra -red (FTIR) spectra showed that the presence of oxirane ring for EPO while the presence of hydroxyl group and the absence of oxirane ring for polyol -PO. 13 1 The C-NMR and H-NMR spectra confirmed that the presence of epoxide profile on EPO while hydroxyl profile on polyol-PO. About 94.7 % of oxirane cleavage for continuous hydrolysis reaction and 95.7 % for batch reaction were recorded. 190 3rd ICYC 2010 Universiti Sains Malaysia ORG-O12 FUNCTIONALIZATION OF GLYCOLIPIDS WITH MACROCYCLES Karem J. Sabah, Thorsten Heidelberg and Rauzah Hashim 23rd-25th June 2010 Chemistry Department, Faculty of Science, University of Malaya, 50603 Kuala Lumpur, Malaysia E-mail: email@example.com Glycolipids are natural materials with amphiphilic behavior. They hav e been applied as biosurfactants in biomedical applications due to their degradability and biocompatibility. Unfortunately, the solubility of industrial glycolipids in aqueous solutions is insufficient for several applications due to the dominant of the hydrophobic lipid tail over the hydrophilic head group (sugar unit). A strategy to increase the hydrophilicity of glycolipids applies the introduction of ethylene glycol units on the sugar, thus hydrophobic dominating SPAN® surfactant have been con...
