Abstract

Si isomerizza 1, 1, 2-trifluoro-1, 2-dicloroetano (A123a) a 1, 1, 1-trifluoro-2, 2-dicloroetano (A123) ponendolo a contatto con A1F3 a temperature comprese tra 180 e 400°C.Si opera opportunamente con miscele di A123a con A123 e/o altri clorofluorocarburi, provenienti dalla preparazione di A123 per idrofluorurazione del percloroetilene.
