Description

General description

2-Ethoxyethanol is a glycol ether. It has been reported as a precursor for ethoxyacetic acid (EAA). Various physical properties (density, refractive index, viscosity and speed of sound) of its binary mixtures with n-alkanes, 2,2,4-trimethylpentane and cyclohexane have been evaluated. High-pressure vapor-liquid equilibrium (VLE) data of its binary mixtures with CO2 have been reported. It can be used as a solvent in the spectrophotometric determination of iron(III) by using the ligand, N,N-bis(2-hydroxy-5-bromo-benzyl)1,2 diaminopropane (HBDAP).

Application

2-Ethoxyethanol (Ethylene glycol monoethyl ether) has been used in zebrafish embryotoxicity test (ZET). It can act like a co-surfactant in the separation of highly hydrophobic analytes via microemulsion electrokinetic chromatography and solvent-modified micellar electrokinetic chromatography.
