DENSITY AND COMPRESSIBILITY OF 4 HIGHER ALCOHOLS FOR PRESSURES TO 2800-KG PER SQ CM

Data are reported on the density and compressibility of glycerol, 1,3-butanediol, 2-methyl-2,4-pentanediol, and 1,5-pentanediol, over the range -50° to 80° C. from atmospheric pressure to 2800 kg. per sq. cm. The data are estimated to be accurate to better than 1 part in 2000. At atmospheric pressure the reciprocal density was linear with temperature. As a function of temperature and pressure, the density can be represented within experimental accuracy by a Tait equation of the form p-1(T,P) = p-1(T,O) - a0 loge {[P+B(T)]/[1.0332 + B(T)]}. The ratio of specific heats is determined for glycerol and 1,3-butanediol using the density and ultrasonic velocity data. © 1969, American Chemical Society. All rights reserved.
