A report is given on continous wave CO2 laser induced reactions of iso-PrOH in gas and liquid phases, resp. The products of the reaction are Me2CO, CH3CH:CH2, CO and CH4. The main reaction pathway of iso-PrOH at high excited state appears to be the dehydrogenation to form Me2CO and the minor reaction pathway is the dehydration to form CH3CH:CH2. Furthermore, the presence of CO and CH4 in the reaction mixtures showed that there was some secondary laser sensitive dissociation of Me2CO.
