Total vapour pressure measurements made by a modified static method for (N-methylformamide + ethanol) and for (N-methylformamide + ethanol + water) at the temperature 313.15K are presented. The results have been fitted with various correlation equations. The G(m)(E) values for (N-methylformamide + A) are compared with the G(m)(E) results previously obtained for (N,N-dimethylformamide + A), where A = water or an aliphatic alcohol. Conclusions resulting from this comparison are discussed.
