Thermodynamics of Philicphobic Interaction Shift in Aqueous Tweens 20 to 80

Abstract

Density (ρ ± 10^{-3 kgm-3}), surface tension (γ ± 10^-2 mNm^-1) for 8.4 to 83.6 mmolkg^-1 at 8 mmolkg^-1 interval aqueous polyoxyethylene sorbitan monolaurate (C=12, Tw20), monopalmitate (C=16, Tw40), monostearate (C=18, Tw60) and monooleate (C=18, 1 double bond, Tw80) nonionic surfactants at 293.15 K are reported. Apparent molar volumes (V₂) are derived from densities. The γ is used for surface excess tension (γ^excess), concentration (τ) and area per molecule. The ρ and γ were regressed for ρ⁰ and γ⁰ limiting and slopes for shift from hydrophilic to hydrophobic interactions (philicphobic). The ρ⁰_Tw20>ρ⁰_Tw40>ρ⁰_Tw80 >ρ⁰_Tw60 and V₂⁰_Tw60> V₂⁰_Tw40> V₂⁰_Tw80> V₂⁰_Tw20 as limiting densities and molal volume respectively in opposite order with stronger structural interaction with Tw20 and weaker with Tw60. The γ_water >γ⁰_Tw80 >γ⁰_Tw40 >γ⁰_Tw20>γ⁰_Tw60 inferred 18% weaker cohesive force (CF) and 22.68% with T60.
