Ned from Fisher Scientific. Sulfuric acid and 4ethylhexanol have been obtained from Merck. Hexane was obtained from Aldrich. All other chemicals and reagents were obtained from Aldrich Chemical (Milwaukee, WI). All components had been utilised without having further purification. All organic extracted had been dried making use of anhydrous magnesium sulfate.The reaction scheme for the formation in the diesters is provided in Figure 1. Sulfuric acid (conc. H2SO4, 10 mol ) was added to a stirred suspension of 9,10,12tris (stearoyloxy) octadecanoic acid four (3.35 mmol) in 4ethylhexanol (three.35 mL). The suspension was stirred and heated to 60 for two h. Next, hexane (five mL) was added, as well as the option was washed as soon as every single with saturated aqueous NaHCO3 (0.five mL) and brine (two 1 mL), dried (MgSO4), filtered, and concentrated under vacuum for six h to yield the target item. The molecular weight was determined applying LCMS (ToF) Bruker Delton qToF. The molecular weight determined was 1244.07.Salih et al.
