Abstract
Studies have been made of the effect of 2-methoxy ethanol (ethyl cellosolve), 2-ethoxy ethanol (ethyl cellosolve) and 2-butoxy ethanol (butyl cellosolve) on the temperature corresponding to the adiabatic compressibility minimum of water (TACM), in view of the special industrial importance of these materials. The studies indicate that these cellosolves act as water structure breakers and that their structure breaking ability follows the order 2-butoxy ethanol < 2-ethoxy ethanol < 2-methoxy ethanol. At 25°C the cellosolves have been found to be hydrophobic, on the basis of ultrasonic absorption and velocity measurements; however, as structural interactions are sensitive to temperature it is quite possible that the trend may change at high temperatures as was revealed in the present TACM studies.
