A study on the interactions between chloral hydrate and ethyl alcohol at the water/air interface

The coadsorption of chloral hydrate and ethyl alcohol at free surface of water was investigated. The additive effect of the electric surface potentials and surface tensions of mixed adsorbed films was observed. Using the parameter β related to molecular interaction in the mixture and calculated values of ΔV (changes in surface potential), the lack of interactions between adsorbed molecules was found.
