Form of the phase diagrams in the coordinates "temperature-density", critical and maximum temperature of liquid and vapor phases coexistence for binary mixtures (n-C-5, n-C-6, n-C-8, n-C-11) + benzene, n-C-5 + toluene and Fr-C-5 + 2-methylbiphenyl were determined by isochoric method. Their interrelation with the difference of the critical temperatures of components forming the mixture was determined. The prediction method was developed and tested using own experimental and literature data on critical and maximum temperatures of binary mixtures of aromatic hydrocarbons with alkanes and cycloalkanes.
