Abstract
Carboxylic acid esters of tertiary alcohols are prepared by reacting an isoolefine with a carboxylic acid having one to five carbon atoms and boiling at between 100 DEG and 200 DEG C. in the presence of a difficulty volatile strong acid having an equilibrium pressure of 1 atmosphere above 200 DEG C. as a catalyst, distilling the complete reaction mixture under reduced pressure and recovering the ester from the more readily volatile fraction. The distillation is preferably carried out at between 0,1 and 100 mm. Hg. pressure. The process may be continuous and the more difficulty volatile fraction containing the acid and the isoolefine from the more volatile fraction returned to the reaction zone. The amount of isoolefine in the reaction zone may be 60 to 95% of the theoretical amount. Suitable carboxylic acids include, formic, acetic, propionic, butyric, isobutyric, isovaleric, acrylic, methacrylic, chloracetic, a -chloracrylic acids. Isoolefines may be 2-methylbutene-(1), 2-methylbutene(2), isobutene. Suitable acid catalysts include sulphuric acid, chlorosulphonic acid, p-toluene sulphonic acid.
