The rarefaction wave data available from literature relies upon the assumption that any discontinuous solutions of gas-dynamic equations should be derived by disappearing viscosity method. In this study the rarefaction wave properties were gained analytically for the case of gas-dynamic equations regularization using interphase kinetics. It is proved that if equations-of-state for two pure phases do not overlap, then rarefaction waves, obtained with the artificial interphase kinetics coincide with those obtained with the disappearing viscosity. If equations-of-state for pure phases do overlap these shock waves differ essentially. It is confirmed by 1D gas-dynamic calculations.
