| titleOfInvention | Preparation method of high-purity isooctanoic acid |
| abstract | The invention provides a preparation method of high-purity isooctanoic acid, which is characterized in that 2-ethylhexanal obtained by condensing and hydrogenating n-butyl aldehyde is mixed with a certain amount of water and then is contacted with an acid catalyst, so that a small amount of 2-ethyl-2-hexenal contained in the 2-ethylhexanal is converted into 2-ethyl-3-hydroxyhexanal; then the treated 2-ethylhexanal mixture is oxidized and then is rectified and separated, and 2-ethyl-3-hydroxycaproic acid and isooctanoic acid are separated by azeotropy of 2-ethyl-3-hydroxycaproic acid and water to realize the purification of isooctanoic acid. The method can obtain the high-purity and high-quality isooctanoic acid product, has simple process flow and can be used for industrial production. |
