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.
三氯乙烷,例如1,1,1-三氯乙烷,在加工过程中稳定在容易热分解的温度下,通过在存在稳定自由基稳定剂的情况下进行处理来实现稳定,例如,具有2,2,6,6-四(较低烷基)-1-哌啶氧自由基团的材料,如2,2,6,6-四甲基-4-羟基-1-哌啶氧自由基。
