Alkyl glisidyl ether compounds are known to have benefits as surfactant-making intermediates. Oleyl <br /> <br /> glycidyl ether sulfonate is an anionic surfactant derived from renewable source. In general, synthesis of <br /> <br /> sulfonate compounds is carried out using SO3 gas. SO3 gas easily reacts with water to form highly <br /> <br /> corrosive H2SO4. Therefore, alkyl epoxy glycidyl ether is used as an intermediate compound to produce <br /> <br /> sulfonate compounds without using SO3 gas. This sulfonate compound is synthesized through two stages, <br /> <br /> namely etherification and sulfonation. Etherification was carried out using oleyl alcohol and <br /> <br /> epichlorohydrin as precursors. Etherification was carried out in two methods, namely etherification <br /> <br /> without phase-transfer catalyst (PTC) and etherification using PTC. Etherification without PTC produced <br /> <br /> dioleyl ether compounds with a yield of 11.9%. Etherification using PTC produced oleyl glycidyl ether <br /> <br /> ((Z) -2- ((octadec-9-en-1-iloxy) methyl) oxirane) compound (1) with a yield of 58.9%. Epoxy glycidyl <br /> <br /> ether was sulfonated using a mixture of sodium bisulfite (NaHSO3) and sodium sulfite (Na2SO3). <br /> <br /> Sulfonation reaction produces sulfonate compound ((Z) -2-hydroxy-3- (octadec-9-en-1-iloxy) propane-1- <br /> <br /> sulfonate) (2) with a yield of 0.2%. .All product of the synthesis were purified by column <br /> <br /> chromatoghraphy and pure product were characterized by 13C NMR and 1H NMR. <br /> <br /> Reagents : (i) NaOH (2 eq), TBAB (6,25x10-3 eq); (ii) NaHSO3 (1 eq), Na2SO3 (2 eq), H2O. <br /> <br /> Key word
