Destructive catalytic conversions of propene by the action of hydrogen chloride and oxygen are of complex character and may proceed by several routes, depending on the oxygen and hydrogen chloride contents in the reactants. Elucidation of the character of these routes is of practical interest, and is necessary for selection of the process conditions. In view of this , the influence of the hydrogen chloride:propene ration on the process was studied in the ranges from 0 to 6 (contract time 2 sec) and from 6 to 12 (contact time 5 sec) at the constant stoichiometric ratio HCl:O//2 equals 2. The interaction of propene with hydrogen chloride at HCl:C//3H//6 ratios from 6 to 12 (Fig. lb) has certain peculiarities, with chlorinolysis of hexachloropropene. However, at HCl:C//3H//6 ratios from 9 to 10. 5 acrolein is formed and then converted into various compounds with evolution of the corresponding amounts of carbon monoxide. It is shown that the conversions of propene into various compounds proceed by two routes, with intermediate formation of allyl chloride and acrolein.
