A process for preparing a halohydrin of a water-miscible olefin comprising: reacting a water-miscible olefin in water with a compound of the formula (I)
wherein R1 and R2 independently represent a branched or unbranched, substituted or unsubstituted, lower alkyl having from 1 to 5 carbons and X is a halogen, to thereby form the halohydrin of the water-miscible olefin.
