Vapor-liquid equilibrium to the twelve binary system acrylic, methacrylic, ethacrylic acids in organic solvents was investigated by the static tensiometric method. The activity coefficient of components and partial pressures were calculated by temperature dependence of saturated vapor. The temperature boiling and condensation at 101,3 kPa was determined for four solutions of methacrylic acid in organic solvents: benzene, acetonitril, heptane and acetic acid by circulated ebulliometer method. The excess thermodynamics functions were calculated by concen- trated and temperature dependences of activity coefficients of components.
