Title: | Microwave-assisted preparation of naphthenic acid esters | Authors: | Ćirin-Novta V. Kuhajda K. Kevrešan S. Kandrač J. Grbović L. Vujić D. |
Issue Date: | 1-Dec-2006 | Journal: | Journal of the Serbian Chemical Society | Abstract: | The synthesis of esters of natural petroleum acids of the naphthenic type assisted with microwave irradiation under the conditions of acid catalysis was carried out with various alcohols: methanol, ethanol, n-butanol and tert-butyl alcohol. Microwave dielectric heating of the reaction mixture in an unmodified microwave oven with activation of the naphthenic acids with sulfuric and p-toluenesulfonic acid afforded the esters of the naphthenic acids. Depending on the catalyst and the steric and nucleophilic properties of the alcohols, the yield of naphthenic esters ranged from 31.25 % to 88.90 %. As a consequence of microwave dielectric heating, the esterification time was reduced from 6-10 h to 5 min. | URI: | https://open.uns.ac.rs/handle/123456789/10721 | ISSN: | 03525139 | DOI: | 10.2298/JSC0612263C |
