Corrosion Inhibition of Carbon Steel in Hydrochloric Acid Solution using Non-Ionic Surfactants Derived from Phenol Compounds

International Journal of Electrochemical Science, 2015
Nonionic surfactants derived from phenol compounds inhibit the corrosion of carbon steel in 1.0 M HCl solution using galvanostatic polarization, electrochemical impedance spectroscopy, potentio-dynamic anodic polarization and weight loss techniques.

Soret Effect in a Nonionic Surfactant System [PDF]

, 2006
We studied the thermal diffusion behavior of C10E8 (decyl octaethylene glycol ether) in water by means of thermal diffusion forced Rayleigh scattering (TDFRS). We determined the two diffusion coeffi- cients D T, D and the Soret coefficient S T in a concentration range from w = 5 wt% to 25 wt% in a temperature range from T = 20 °C to 40 °C. The obtained

CHARACTERIZATION OF POLYETHOXYLATED ALKYL PHENOLS WITH A HIGH DEGREE OF ETHOXYLATION AT THE SOLID-LIQUID INTERFACE [PDF]

, 2016
Fully characterizing the behavior of a surfactant, from the mechanism of adsorption to the formation of micelles, is vital when taking the surfactant out of the lab and into the real world.

Precipitating polyelectrolyte–surfactant systems by admixing a nonionic surfactant – a case of cononsurfactancy

, 2017
Thermodynamic and structural investigations reveal the origin of the unexpected formation of insoluble complexes upon admixing nonionic surfactants to polyelectrolyte/anionic surfactant complexes.

Surfactant-Assisted Ozonolysis of Alkenes in Water: Mitigation of Frothing Using Coolade as a Low-Foaming Surfactant

, 2022
Aqueous-phase ozonolysis in the atmosphere is an important process during cloud and fog formation. Water in the atmosphere acts as both a reaction medium and a reductant during the ozonolysis.

Molecular dynamics simulation study on the effect of SDS and AEO3 complex on the wettability of lignite

Meikuang Anquan
In order to explore the micro-mechanism of the influence of anionic surfactant and nonionic surfactant on the wettability of low-rank coal, the molecular dynamics simulation method (MD) was used to study the influence of anionic surfactant (SDS ...

Interplay between the surface adsorption and solution-phase behavior in dialkyl chain cationic-nonionic surfactant mixtures.

, 2009
Neutron reflectivity, NR, and surface tension have been used to study the adsorption at the air-solution interface of mixtures of the dialkyl chain cationic surfactant dihexadecyl dimethyl ammonium bromide (DHDAB) and the nonionic surfactants monododecyl
