Abstract

1. A process for the hydroxylation of 3-chloro-2-methylpropene-1, of straight- or branched- chain monoolefins which are unsubstituted or are already substituted by 1 or 2 hydroxyl groups and have 4 to 7 carbon atoms and a terminal or internal double bond, of straight- or branched- chain monoolefins which are unsubstituted or are already substituted by 1 or 2 hydroxyl groups and have from 8 to 10 carbon atoms and an internal double bond, or of straight- or branched- chain diolefins having from 4 to 10 carbon atoms, characterised in that the olefin to be hydroxylated is reacted at a temperature of from 30 to 80 degrees C with less than 2 mols of formic acid and less than 2 mols of hydrogen peroxide, in each case per mol of double bond to be hydroxylated, formic acid of a concentration of from 20 to 100% by weight is used and hydrogen peroxide of a concentration of less than 50% by weight is used, and the concentration of the hydrogen peroxide in the aqueous phase of the reaction mixture is maintained below 15% by weight for the complete duration of the reaction.
