Potassium Hydroxide → Sodium 4-(6-hydroxyhexyl)oxybenzenesulfonate

Participants

Reaction Steps

Into a three-necked round-bottom flask equipped with a magnetic stirring bar and a reflux condenser were added 4-hydroxybenzenesulfonicacid sodium salt (30.0 grams (g), 0.13 mol), potassium hydroxide (9.0 g, 0.16 mol) and distilled water (60 milliliter (ml)). 1-Bromohexanol (23.16 g, 0.13 mol) dissolved in ethanol (50 ml) was added drop wise into the reaction mixture at room temperature. The reaction mixture was refluxed for 24 hours and then cooled to room temperature. The precipitated product was filtered and washed with chloroform to remove excess of 1-bromohexanol. The product was dried under vacuum at 70° C. for 12 hours to provide 38.06 g of sodium 4-(6-hydroxyhexyl)oxybenzenesulfonate (92% yield).
