In order to investigate the phonon dynamics of molten NaI, inelastic X-ray scattering measurements were preformed near the melting point at the beamline BL35XU of the SPring-8. A fast sound mode exceeding the ultrasonic velocity of sound by about 45% was observed as in other molten alkali halides, which is in fairly good agreement with a scaling formula using the effective mass of the salt constituents.
