<p>Trichloroethane, e.g., 1,1,1-trichloroethane, is stabilized during processing at temperatures at which it is susceptible to thermal decomposition by conducting such processing in the presence of a stabilizing amount of a stable free radical stabilizer, e.g., a material having a 2,2,6,6-tetra(lower alkyl)-1-piperidinyloxy-yl free radical group such as 2,2,6,6-tetramethyl-4-hydroxy-1-piperidinyloxy.</p> |
