Water/Chlorocarbon Winsor I ⇔ III ⇔ II Microemulsion Phase Behavior with Alkyl Glucamide Surfactants
Publikováno v:
Environmental Science & Technology. 30:2143-2147
The investigation of the microemulsification of chlorocarbons that contaminate aquifers is addressed in this study. The surfactants employed are alkyl glucamidesglucamine coupled with either n-heptanoic, n-nonanoic, or n-dodecanoic acids as well as t

The technology developed for surfactant enhanced oil recovery and toxic spill remediation has been applied to the clean-up of JP4 jet fuel spills on air bases. The EACN for JP4 was determined via previously established mathematical formulae and confi

This is a study of die phase behavior of Propoxylated Guerbet alcohol sodium sulfates C14EX(PO) and C16EX(PO) and Propoxylated tridecyl alcohol sodium sulfates C13(PO) using oil phase composition, water salinity and composition, temperature and propy

Non-ionic surfactants with ethylene oxide (EO) head groups become less soluble in water and wourld partition into an oil phase, if present, as system temperatures are raised. Sucrose and glucose based surfactants have the opposite behavior with tempe

Mixing rules for water/chlorocarbon/anionic surfactant systems have been studied. It was found that the behavior of chlorocarbons parallels the ideal mixing rules for hydrocarbons. The polarity of some chlorocarbons prevented a direct determination o

In most surfactant formulations involving microemulsions, a cosurfactant is generally required in combination with a primary surfactant for several purposes; however, it has previously been shown not to be an absolute requirement and moreover surfact

Commercially viable cosurfactant species of enhanced surface activity were used to formulate middle phase microemulsions. These cosurfactants were made from butanol, with randomly added equal weights of ethoxylate (EO) and propoxylate (PO) groups, to

We synthetized a homologous series of molecules (MVnn'Q) where a methylviologen (MV) and a aminochloronaphtoquinone (Q) are linked to each other via a flexible chain. Using the electron pulse radiolysis technique, we have measured time-resolved spect

Aqueous micellar dispersions of several alkylbenzenesulfonates (xφC12 and xφC16) where x = 1, 2, 3 ... and indicates the position of the phenyl group (φ) along the alkyl chain were prepared and examined for fluorescence emission from the benzene r

Fluorescence polarization, excimer emission, and dynamic light scattering have been used to investigate the effect of system parameters on the physical (translational diffusion coefficient of microemulsion droplets, microfluidity at the oil-water int
