Hydrochloric Acid → Decanoic acid, 2-methyl-

참여 물질

반응 단계

After 14.6 g of concentrated sulfuric acid and 8.6 g (50 mmol) of (-)-2-methyldecanol were added to 96 ml of water, 16.4 g (10.4 mmol) of potassium permanganate was added dropwise over 4 hours while the reaction temperature was held below 25° C. The thus obtained reaction mixture was poured into 300 ml of ice water, added with 30 g of sodium hydrogen sulfite, adjusted to pH of not more than 1 with hydrochloric acid, extracted with ether and then extracted with a 10% aqueous solution of sodium hydroxide. This extract was added with hydrochloric acid to adjust pH to not more than 1 and again extracted with chloroform. The thus obtained extract was washed with water, dried, concentrated, and distilled under a reduced pressure (0.4 mmHg, 116°~120° C.) to obtain 5.2 g (yield 63%) of (+)-2-metyl decanoic acid.
