Chlorinated organic compounds having their resistance to deterioration (when heated, exposed to light or water, or in contact with certain metals such as iron and aluminum) enhanced by a 1,3-dicarbonyl compound having the formula: <IMAGE> I wherein: R1 is selected from the group consisting of hydrogen, hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR1, ester COOR1, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms; R2 is selected from the group consisting of hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR1, ester COOR1, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms; R3 is selected from the group consisting of hydrogen, hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR1, ester COOR1, alkyl and alkoxycarbonyl having from one to about eighteen carbon atoms; and <IMAGE> provided, when both R3 are hydrogen, at least one R1 and R2 is other than methyl as well as metal and organotin enolate salts thereof. The compounds are effective in enhancing the resistance to deterioration of chlorinated hydrocarbons and chlorinated higher fatty acid esters. |
