Abstract
Densities, ρ, speed of sound, u , for aqueous solutions of alkoxyalkanols like ethylene glycol mono methyl ether (EGMME), ethylene glycol mono ethyl ether (EGMEE) and ethylene glycol mono butyl ether (EGMBE) have been measured in aqueous solutions of surfactant sodium dodecyl sulphate (SDS) at temperatures T = (288.15, 298.15, 308.15 and 318.15) K have been measured. The different parameters such as apparent molar volume, limiting apparent molar volume, transfer volume, partial molar expansibility have been derived from density data to study the nature of interactions and also the aggregation behavior of surfactant with alkoxyalkanols. Experimental speeds of sound data were used to estimate apparent molar isentropic compression, limiting apparent molar isentropic compression, partial molar isentropic compression of transfer. The pair and triplet interaction coefficient have been calculated from both the properties. These parameters have been discussed in the light of ion-ion and ion-solvent interactions.
