Autor: Ana Forgiarini, Johnny Bullón, Francia Vejar, José G. Delgado-Linares, Jean-Louis Salager, José Alvarado
Publikováno v: Energy & Fuels. 30:7065-7073
The performance of several extended surfactants as water-in-crude oil emulsion breakers was evaluated using two criteria: (1) the demulsifier dose required (CD*) to attain the minimum stability at the so-called optimum formulation, and (2) the corres

Two families of extended surfactants were prepared with the same head groups (carboxylate, sulfate, disodium phosphate) and different intermediate spacer structures. In one there was an average of 7 propylene oxide groups on the side of the tail and

Synthesis and Physicochemical Characterization of Anionic Surfactants Derived from Cashew Nut Shell Oil
Autor: Jesús Nieves, Francia Vejar, Cesar Scorzza, Johnny Bullón
Publikováno v: Journal of Surfactants and Detergents. 13:27-31
Carboxylate derivatives of cardanol and anacardic acids, which are the main phenolic components of cashew nut shell oil were prepared and tested as anionic surfactants. They lower the surface tension, exhibit a critical micelle concentration, and pro

Effect of Temperature and Other Variables on the Optimum Formulation of Anionic Extended Surfactant–Alkane–Brine Systems
Autor: Ana Forgiarini, Francia Vejar, R. E. Antón, Josmary Velásquez, Jean-Louis Salager, Cesar Scorzza
Publikováno v: Journal of Surfactants and Detergents. 13:69-73
Anionic extended surfactants of the alkyl polypropylene oxide sulfate type are found to obey the linear correlation lnS = k ACN for optimum formulation (three-phase behavior) of ionic surfactant–oil–water systems, with a k value essentially the s

Practical Surfactant Mixing Rules Based on the Attainment of Microemulsion–Oil–Water Three-Phase Behavior Systems
Autor: Francia Vejar, Jean-Louis Salager, Carlos Bracho, José María Andérez, R. E. Antón
Publikováno v: Advances in Polymer Science ISBN: 9783540698098
Surfactant mixture are generally used to fine-tune formulations to an exact property value, such aschanging its hydrophilicity. To do so a precise characterization method has to be used. The presentedtechnique consists of the attainment of a microemu
