Abstract:
A process for preparing hydroxy-substituted monolactones comprising reacting, in the presence of an acidic catalyst selected from the group consisting of organic sulfonic acids, heteropolyacids, and mineral acids, (A) at least one olefinic compound of the general formula:(R.sup.1)(R.sup.2)C.dbd.C(R.sup.6)(CH(R.sup.7)(R.sup.8))wherein each of R.sup.1 and R.sup.2 is, independently, hydrogen or a hydrocarbon based group and each of R.sup.6, R.sup.7 and R.sup.8 is, independently, hydrogen or a hydrocarbon based group provided that at least one is hydrocarbon based group containing at least 7 carbon atoms; and(B) at least one carboxylic reactant selected from the group consisting of compounds of the formulaR.sup.3 C(O)(R.sup.4).sub.n C(O)OR.sup.5 (IV)and compounds of the formula ##STR12## wherein each of R.sup.3, R.sup.5 and R.sup.9 is independently H or a hydrocarbyl group, R.sup.4 is a divalent hydrocarbylene group, and n is 0 or 1 in amounts ranging from 0.6 moles (B) per mole of (A) to 1.5 moles (B) per equivalent of (A).
