Abstract
The ultrasonic speeds in dilute aqueous solutions of eight alkyl aceta tes (methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, and tert-butyl acetates) were measured at (5, 15, 25, 35, and 45) degrees C by means of a sing-around velocimeter. From these data and density results reported previously, the apparent molar isentropic compression s of the alkyl acetates were evaluated. The results were compared with those for more hydrophilic solutes, alcohols reported earlier, and th e effects of chain lengthening and chain branching of the alkyl residu es on the compression behavior were discussed.
