Thin-Layer Chromatography Of Red Dyes And Intermediates

Abstract

Binary homogeneous azeotropic solvent mixtures for thin-layer chromatography of laser dyes and intermediates (cou-marins, naphthalimides, benzanthrones, phenalenones, γ-pyrone derivatives) are proposed with dielectric constants of 2,4 – 19,3 and boiling points of 56,0 – 82,4ºС. For all studied substances well-reproducible Rf values are obtained.
