(Associação Brasileira de Petróleo e Gás, 2019-04-03)
Determinación de los parámetros del modelo de flory-huggins para estimación del punto de nube de surfactantes no iónicos
(Centro de Información Tecnológica (CIT), 2014)
The cloud point of different polyethoxylated surfactants have been experimentally determined and
thermodynamic parameters such as enthalpy and entropy of mixing using the Flory-Huggins model have
been determined. The ...
Influence of sodium chloride on the cloud point of polyethoxylate surfactants and estimation of Flory-Huggins model parameters
(Universidad de Antioquia, 2015-04-05)
Este estudio investigó la influencia de NaCl sobre el punto de niebla de los tensioactivos polietoxilados de la familia de polietoxilatos de alcohol laurílico y polietoxilatos de nonilfenol. Se representaron gráficamente ...
Water activity of aqueous solutions of ethylene oxide-propylene oxide block copolymers and maltodextrins
(Brazilian Society of Chemical Engineering, 2010)
The water activity of aqueous solutions of EO-PO block copolymers of six different molar masses and EO/PO ratios and of maltodextrins of three different molar masses was determined at 298.15 K. The results showed that these ...

Equilíbrio líquido-líquido de sistemas aquosos com tensoativos polietoxilados: dados experimentais e modelagem
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia QuímicaPesquisa e Desenvolvimento de Tecnologias Regionais, 2013-11-11)
The nonionic surfactants when in aqueous solution, have the property of separating into two
phases, one called diluted phase, with low concentration of surfactant, and the other one rich
in surfactants called coacervate. ...
