N2  - Hydrogen iodide catalyses the decomposition of isopropanol into propene and water at 356 to 457°, viz.                            i-C3H7OH+HI &#8594; C3H6+H2O+HI  This is followed by the faster reactions                              C3H6+HI &#8594; i-C3H7I                            i-C3H7I+HI &#8594; C3H8+I2                         i-C3H7OH+I2 &#8594; (CH3)2CO+2HI  The rates of the initial reaction fit the Arrhenius equation                     k2 = 1012.24 exp(-31900/RT) sec-1 ml mole-1   and it is believed to be homogeneous and molecular. It is faster than the corresponding reactions with hydrogen chloride and hydrogen bromide in the ratios 100 : 1 and 5 : 1, respectively. For the overall reaction the amounts of the products formed to 70% reaction, computed with the use of rate constants of the individual reactions, agree well with the amounts found by analysis.
