2-hexyldecanoic acid

反応条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Dinitropropanol (25.5 g, 0.17 mol), 2-hexyldecanoic acid (48.7 g, 0.19 mol) and 50 g of polyphosphoric acid were added to 50 mL of dichloroethane and the resulting mixture was slowly stirred using a stirrer. The solution thus obtained was slowly heated to 70° C. and then reacted for 15 hr (overnight). After the reaction, the temperature of the reactor was lowered to room temperature, and the stirrer was powered off. When the temperature of the reactor was room temperature, the dichloroethane layer was decanted, followed by extraction with a 1 N sodium hydroxide aqueous solution and then distillation under reduced pressure, affording 2,2-dinitropropyl-2-hexyldecanoate (39.6 g, yield: 60%). The solution thus obtained reacted for 15 hr (overnight) After the reaction was lowered to room temperature was room temperature the dichloroethane layer was decanted followed by extraction with a 1 N sodium hydroxide aqueous solution distillation under reduced pressure

実験手順: The synthetic fuel was prepared by using a 1000 ml glass reactor, provided with thermostat, mechanical stirring, sampling outlet, and condensation system. Octanol-1 (300 g) was charged to the reactor and ZnO (2 g), KOH (6 g), CaO (5 g) and Cu Bronze (1.5 g) were added. The above reaction mixture was heated at 200° C. for 8 hours to complete the reaction. The reaction mixture was filtered and purified by distillation to get 2-hexyl-1-decanol (250 g). 2-Hexyl-1-decanol (250 g) was reacted with Jones reagent (200 ml) in acetone (200 ml) to get 2-hexyl-1-decanoic acid. 2-Hexyl-1-decanoic acid produced (200 g) was again charged to the above reactor and subsequently, methanol (200 g) and sulfuric acid (6.0 g) were added slowly to the reactor with stirring. The reaction mixture was refluxed till completion of the reaction. The reaction mixture was passed through basic alumina to get rid of residual catalyst. The catalyst free mixture was fractionated to separate un-reacted methanol and synthetic diesel. Prepared synthetic fuel was evaluated for fuel properties and results were tabulated.

実験手順: Concentrated sulphuric acid (100 g) was diluted with water (750 ml) and this solution was cooled to room temperature and added to a solution of 2-hexyldecanol (242 g) in methylene chloride (600 ml). The solutions were stirred together beneath a reflux condenser and solid potassium permanganate was added in portions during 5 hours so as to maintain gentle boiling of the methylene chloride. The mixture was filtered to remove precipitated manganese dioxide, and the organic layer was separated and washed with water. The solvent was distilled leaving 2-hexyldecanoic acid (222 g) as a nearly colourless oil. The mixture was filtered to remove precipitated manganese dioxide the organic layer was separated washed with water The solvent was distilled
