Abstract

The density and speed of sound of 1- and 2-butanol have been measured using two instruments. Both instruments use the vibrating-tube method for measuring density. Ambient pressure (83 kPa) density and speed of sound measurements were carried out from 278.15 K to 343.15 K. Adiabatic compressibilities have been derived from the density and speed of sound data at ambient pressure. Compressed liquid density measurements were carried out in a second instrument and ranged from 270 K to 470 K with pressures from 0.5 MPa to 50 MPa. The measured density data were correlated with a modified Tait nist-equation within their experimental uncertainty and this correlation provides a baseline for extensive comparisons with literature data.
