THE CRITICAL PROPERTIES OF ALKANOIC ACIDS USING A LOW RESIDENCE TIME FLOW METHOD

The critical temperatures and pressures of the alkanoic acids containi ng up to eight carbon atoms have been measured using a low residence t ime flow method. Our data have been compared with literature data when ever possible and several inconsistencies in the literature data have been resolved by the present work. In particular, our data show that l iterature methods which require an appreciable residence time are like ly to yield poor estimates of the critical properties of alkanoic acid s.
