摘      要:The determination of the osmotic coefficients of the aqueous solution of polyhydroxylated compounds such as glycol, glycerol, sucrose and glucose by Vapour PressureOsmometry at 313, 323 and 333K was carried out over the concentration range of ***-1 and 0.0-2.0 ***-1 respectively. By using a linear least-square fitting routine,the osmotic coefficients were fitted by a simPle polynomial equation, It was found thatthe relation between the experimental results of molal osmotic coefficients and the massmolal concentration of the solution m are in agree with that from the polynomial fit-ting at different temperature. Factors which imldence the osmotic coefficient such as thenumber of hydroxyl of polyhydroxylated compounds or the molecule weight of the solutemolecules should be further studied, this work will also contribute to the studies of otherthermodynamical properties of the aqueous solution of polyhydroxylated compound.
