Solubility parameters, hydrophile-lipophile balance, and solubility in sucrose derivative surfactants obtained by GLC

Abstract

Specific retention volumes of different solvents were measured on coIumns containing two sucrose derivatives esters as stationary phase.Henry's constants were calculated and the solubility in the surfacnnts was obtaíned. The solubilíty parameters of the surfactants were obtained at different temperatures. The relation between solubility parameter and hydrophilíc - lipophilic balance was discussed and the results obtained in both surfactants are presented.

Se midieron los volúmenes de retención espeeíficos de distintos solventes en columnas que contenídn derivados de esteres de sacürosa comofases estacionarias. Se calcularon las constantes de Henry y se ha obtenído la solubilidad de los sdventes en dos esferes de sacarosa. Se calcularon los parámetros de solubilidad de las sudactantes a díferentes temperaturas. Finalmente, se ha discutido la relacíón entre parámetro de solubilidad con el balanee hídrofiIico - Iipofílica y se analizaron los resultados obtentdos en ambos sttrfactantes.
