Thin-Layer Chromatographic Study of Some Reactive Dyes and Fluorescent Brighteners and Their Intermediates Containing Stabilizer Fragment for Textile and Polymers

摘要

Thin-layer chromatographic (TLC) study on nine reactive dyes, seventeen fluorescent brighteners (nine of them are triazine-stilbene derivatives and eight - derivatives of 2-aminodimethylterephthalate), and their intermediates (twenty four in number), all of them containing 4-amino-2,2,6,6-tetramethylpiperidine stabilizer fragment, was performed. These compounds were synthesized for simultaneously bleaching or coloration and stabilization of fabrics or polymers; some of them were able to copolymerize with appropriate monomers like acrylonitrile, methyl methacrylate, and acrylamide. The most suitable stationary and mobile phases for separation, ultraviolet (UV) light as detector, and TLC technique for detection were found. The TLC method was suitable and reliable for monitoring both the synthesis and the purity of the compounds.
