The massic heat capacity values c(p) of CFCl3 and CF2ClCFCl2 and of (0.5CFCl(3) + 0.5CF(2)ClCFCl(2)) were measured with high accuracy with a flow apparatus. The results for the pure substances were published in an earlier paper. The present paper contains the results for the mixture. The density of the data on the (p, T)-surface is enlarged in the critical regions of the pure substances. This should enlarge the sensitivity with which mathematical models for the mixing effect can be adapted to the data.
