THE VAPOR-PRESSURE OF SATURATED AQUEOUS-SOLUTIONS OF D(-GLUCOSE, D(+)-GALACTOSE, AND BETA-LACTOSE AT TEMPERATURES FROM T = 278 K TO T = 318K())

Vapour pressures of saturated aqueous solutions of D(+)-glucose, D(+)- galactose, and beta-lactose were determined in the temperature range ( 278 to 323) K using an electronic hygrometer with an electrolyte senso r, and were compared with literature data. The water activities and os motic coefficients at the saturation point were evaluated from the det ermined vapour pressures at T = 298.15 K. (C) 1998 Academic Press.
