Claims
- 1. A process for the hydrogenolysis of carbon tetrachloride comprising:
- contacting said carbon tetrachloride with at least 0.1 mole of hydrogen per mole of said carbon tetrachloride in an empty reaction vessel of nickel, iron or their alloys at a pressure within the range of from 0 psig to 1000 psig, at a temperature within the range of from 350.degree. C. to 700.degree. C. and for a time sufficient to produce CH.sub.2 Cl.sub.2.
- 2. The process of claim 1 wherein the temperature ranges from 400.degree. C. to 700.degree. C. and the pressure is from 0 to 500 psig.
- 3. The process of claim 1 wherein less than 10% olefinic by-product is produced.
- 4. The process of claim 1 wherein less than 10% of hydrocarbons are produced.
- 5. The process of claim 1 wherein chloroform is produced.
- 6. A process for the hydrogenolysis of carbon tetrachloride comprising:
- contacting said carbon tetrachloride with at least 0.1 mole of hydrogen per mole of said carbon tetrachloride in a reaction vessel of nickel, iron or their alloys which is packed with formed shapes of aluminum, molybdenum, nickel, iron, cobalt, or their alloys, at a pressure within the range of from 0 psig to 1000 psig, at a temperature within the range of from 500.degree. C. to 700.degree. C. and for a time sufficient to produce CH.sub.2 Cl.sub.2.
- 7. The process of claim 6 wherein said packing is in the form of perforated plates, saddles or rings.
- 8. The process of claim 7 wherein said packing is in the form of perforated plates.
- 9. The process of claim 8 wherein the packing is of nickel or a nickel alloy.
- 10. The process of claim 8 wherein chloroform is produced.
- 11. A process for the hydrogenolysis of carbon tetrachloride comprising:
- contacting said carbon tetrachloride with at least 0.1 mole of hydrogen per mole of said carbon tetrachloride in a reaction vessel of nickel, iron or their alloys which is empty or is packed with formed shapes of aluminum, molybdenum, nickel, iron, cobalt, or their alloys, at a pressure within the range of from 0 psig to 1000 psig, at a temperature within the range of from 500.degree. C. to 700.degree. C. and for a time sufficient to produce CHCl.sub.3.
- 12. The process of claim 11 wherein the reaction vessel is empty.
- 13. The process of claim 12 wherein the pressure is from 0 to 500 psig.
- 14. The process of claim 12 wherein less than 10% olefinic by-product is produced.
- 15. The process of claim 12 wherein less than 10% of hydrocarbons are produced.
- 16. The process of claim 11 wherein the reaction vessel is packed.
- 17. The process of claim 16 wherein said packing is in the form of perforated plates, saddles or rings.
- 18. The process of claim 17 wherein said packing is in the form of perforated plates.
- 19. The process of claim 18 wherein the packing is of nickel or a nickel alloy.
- 20. The process of claim 11 wherein CH.sub.2 Cl.sub.2 is also produced.
