Speed of sound and density measurements for difluoromethane. Speed of sound was measured in the liquid phase using a dual-path pulse-echo instrument at temperatures between 230 and 345 K, with pressures from 2.1 to 70 MPa. Vapor-phase density was measured using a dual-sinker densimeter instrument at temperatures from 240 to 340 K and pressures from 0.1 to 1.61 MPa.
