Stabilization of cf (arrow down) 3 (arrow down) - chcl (arrow down) 2 (arrow down) or cclf (arrow down) 2 (arrow down) - chclf or mixtures thereof against the reaction with kaeltemaschinenoel

摘要

the invention concerns a method for stabilization of cf3 - chcl2 (r123) or cclf2 - chclf (r123a) or their mixtures against reaction with ku00e4ltemaschinenu00f6l, wherein the chlorofluorocarbons or the mixture of chlorofluorocarbons 2.4 - diphenyl - 4 - methyl - penten hits.the invention relates to a further $a mixture which essentially from 2.4 - diphenyl - 4 - methyl - penten and at least one of the compounds cf3 - chcl2 and cclf2 - chclf exists.
