Popis:	The refractometric method is used to demonstrate hydrogen-bond complex formation between aromatic chloro-groups and the α-methene or -methylene groups of ester residues. The bond between chlorobenzene and ethyl acetate has an energy ∼ −3kcal. /mole in aqueous ethanol. This type of bond probably assists the adsorption by cellulose acetates of dyes containing chloro-groups. Chlorobenzene is strongly adsorbed by cellulose triacetate, probably by this mechanism. The hypothesis of -Cl … HC-bonding may assist in the interpretation of the relative degrees of plant growth-hormone activity of chlorinated aryloxyacetic acid derivatives.
