Methods for destroying ozone depleting substances |
| abstract |
Ozone depleting fluorocarbon compounds are dehalogenated through more economic partial reduction reactions with solvated electrons formed from lower equivalents of reactive metals than previously employed. The partially reduced products are further dehalogenated with non-aqueous liquid nitrogen-containing bases, such as ammonia in the same reaction mixture, or alternatively, in an independent reaction by treating with ammonia or other base alone. In other embodiments, mixtures of fluorocarbon refrigerants including difficult to separate azeotropes of dichlorodifluoromethane contaminated with chlorodifluoromethane are reclaimed by treating only with weak non-aqueous nitrogen-containing bases to provide essentially chemically pure dichlorodifluoromethane refrigerant suitable for recycling/reuse. |
