Substantivity of azoic coupling components "azotols"

A correlation between the chemical structure of azoic coupling components ( hereafter referred to as azotols) and their affinity for cotton has been at tempted. The theoretically computed correlation equations of the practical affinity with the van der Waals surface, the molecular volume and the hydro phobicity are reported. The hypothesis of microcrystalline multilayered mic elles' implication in the sorption of azotols to a cellulose support is sus tained. (C) 1998 Elsevier Science Ltd. All rights reserved.
