Abstract
In the preparation of alkyl halides from cycloaliphatic olefins and hydrohalic acids, the reaction is carried out at a temperature below the boiling point of the olefin without the addition of catalyst and without a solvent. At a high olefin conversion rate, alkyl halides are obtained with high selectivity and with very good color quality.
