2-Heptanol → 1-Methylhexyl acetate

참여 물질

반응 단계

2-Heptanol (162 g, 1.4 mol, Aldrich) and sodium acetate (16 g, Aldrich) were heated to 100° C. and then acetic anhydride (190 ml, BDH GPR) was added over a 1 hour period at 100-130° C. The mixture was heated to reflux for 3 hours. The reaction mixture was then cooled, washed with water, washed with aqueous sodium bicarbonate to neutrality, dried over sodium sulfate, and then concentrated. Fractional distillation of the crude residue under vacuum provided 1-methylhexyl acetate (107-108°/95-100 mm Hg, 67% yield), the structure of which was confirmed by mass spectroscopy, nuclear magnetic resonance spectroscopy, and infra red spectroscopy (not shown).
