If some other Scientists have found out that Sodium Oxalate from Rhubarb plant can turn ozone depleting substance into ordinary salts, is there already an existing research project in wider scale regarding this?

If there is, I want to know where, when and who are they?

A search of yielded the following:

Perhaps helpful.

The article I have read reporting on this work is: Burdeniuc, Juan, and Robert H. Crabtree. "Mineralization of Chlorofluorocarbons and Aromatization of Saturated Fluorocarbons by a Convenient Thermal Process." Science 271 (1996): 340-41. The article is on the web at,

however, you need a subscription to the journal to view it.

Robert Crabtree is a professor in the Chemistry Department at Yale University. His web site is at His research group investigates many areas of inorganic chemistry, one of which is the chemistry of fluorocarbons. These are ordinarily some of the most degradation-resistant carbon-containing compounds known. Since publishing the article on the degradation of fluorocarbons by contact with hot sodium oxalate, they have published several other articles on degrading fluorocarbons using light and different catalysts.
