SUMMARY

The discussion focuses on methods to break down dichlorodifluoromethane, specifically highlighting dissolving metal reduction using sodium in ammonia (Na/NH3), UV photolysis, and thermal decomposition. A critical warning is issued regarding the decomposition of dichlorodifluoromethane into phosgene gas, a highly toxic substance, at temperatures exceeding 1000°F. Additionally, the potential release of free chlorine gas and the formation of hydrochloric and hydrofluoric acids during decomposition are emphasized, underscoring the need for caution in handling these reactions.

PREREQUISITES
  • Understanding of chemical reduction methods, specifically dissolving metal reduction.
  • Familiarity with photolysis and its applications in chemical reactions.
  • Knowledge of thermal decomposition processes and their implications.
  • Awareness of toxic gases and safety protocols in chemical handling.
NEXT STEPS
  • Research the safety protocols for handling phosgene gas and other toxic byproducts.
  • Learn about the mechanisms of UV photolysis in organic compounds.
  • Explore the properties and risks associated with hydrochloric and hydrofluoric acids.
  • Investigate the applications of dissolving metal reduction in organic chemistry.
USEFUL FOR

Chemists, chemical engineers, safety professionals, and anyone involved in the handling or decomposition of chlorinated hydrocarbons.

Hi people, I was wondering what method could I use to break down such a bond. Thanks for answering

Dissolving metal reduction like Na/NH3, UV photolysis and thermal come to mind.
 
Just a warning on this, as better to be safe than sorry. Please be aware that dichlorodifluoromethane decomposes into phosgene gas--a highly toxic and deadly nerve agent--at temperatures above about 1000 deg. F. Also free chlorine gas can be liberated under the right conditions as well. Please be careful!

how does that decompose into phosphine? where would the phosphorus come from?

I think he said phosgene which is O=C(Cl)2, the fully chlorinated analog of formaldehyde.

It could happen in the presence of oxygen.
