- PROCESS FOR THE PRODUCTION OF CHLORINATED ALKANES
-
Processes for the production of chlorinated alkanes are provided. The present processes comprise dehydrochlorinating one or more trichloroalkanes having from 3-6 carbon atoms and vicinal chlorine atoms, followed by a series of sequential chlorination and/or further dehydrochlorination steps. Because the trichloroalkane is first dehydrochlorinated, rather than being first chlorinated, greater specificity to desired tetra- and pentachloroalkanes can be seen.

- PROCESS FOR THE PRODUCTION OF CHLORINATED AND/OR FLUORINATED PROPENES
-
The present invention provides one-step processes for the production of chlorinated and/or fluorinated propenes. The processes provide good product yield with low, e.g., less than about 20%, or even less than 10%, concentrations of residues/by-products. Advantageously, the processes may be conducted at low temperatures than 500° C. so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts or initiators may provide additional enhancements to conversion rates and selectivity, as may adjustments to the molar ratio of the reactants.

- TWO ROUTES OF PROPENE CONVERSION INTO PERCHLORO DERIVATIVES BY THE ACTION OF HYDROGEN CHLORIDE AND OXYGEN.
-
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.
