A number of thermoacoustic parameters, including the Sharma constant S 0 , the isochoric temperature coefficient of volume expansivity (d Inα/d In T ) V , the isochoric temperature coefficient of internal pressure (d In P i /d In T ) V , reduced volume V, reduced compressibility β and the Huggins parameter F, are estimated by using only the volume expansivity α from the density temperature data for a number of methyl esters of n ‐alkanoic acids. The methyl esters give excellent separation of saturated fatty acid mixtures. The Sharma constant, which relates the molecular constant n and other thermoacoustic parameters, is a constant with a characteristic value of 1.11+0.01 for all these esters.
