The critical properties of alkanoic acids using a low residence time flow method

The critical temperatures and pressures of the alkanoic acids containing up to eight carbon atoms have been measured using a low residence time flow method. Our data have been compared with literature data whenever possible and several inconsistencies in the literature data been resolved by the present work. In particular, our data show that literature methods which require an appreciable residence time are likely to yield poor estimates of the critical properties of alkanoic acids.
