说明

一般描述

Tetraethylene glycol monododecyl ether (C₁₂E₄) is a nonionic surfactant.[1] It is used as a stabilizer in several phase behavior and evaporation studies.[2] This polyoxyethylated lauryl ether surfactant[3] is a water-soluble surfactant.[4]

应用

Tetraethylene glycol monododecyl ether (C₁₂E₄) has been used:

as a water-soluble surfactant in computational and physical experiments to report the post-deposition motion of the surfactant front and the deformation of the subphase surface using Marangoni flow and capillary waves[4]
to study its mixed micellization and interfacial properties in the absence and presence of sodium propionate[5]
to investigate the phase transformation of C₁₂E₄ aqueous solutions by Rayleigh light scattering (RLS) when adopting different heating ways[6]
