Resumo

The objective of this paper is to present surface tension of mixtures of 2,2,2-trifluoroethanol (TFE) and N-methyl-2-pyrrolidone (NMP) which are thought to be most important in the near future as a working fluid of an absorption machine. Therefore, the surface tension was measured by a differential capillary rise method over the entire mass concentration range at temperatures of 10 to 40°C. The experimental values were correlated with temperature and with mass concentration. The average deviation was 0.8%.
