In this article,T, P and total composition data of 9 binaries for the products in the methanol amination with ammonia, which includes NH_3-methanol (MeOH),NH_3dimethylamine (DMA),NH_3-monomethylamine (MMA), NH_3-H_2O,DMA-MeOH, DMA-H_2O, MMA-MeOH,MMA-H_2O and MMA-trimethylamine (TMA),were measured over a temperature range of 20-120℃. The molar fractions for each component were calculated by using indirect method and parameters of Wilson equaiton were correlated as a function of temperature.The maximum relative error was 1.7% according to the accuracies of instruments used.
