- W1995255090 abstract "Abstract A method for the qualitative and quantitative analysis of the linear oligomers of the ester-diol type and ester-hydroxy acid type from ethylene terephthalate is described. As thin-layer chromatographic solvent systems, a chloroform-ethanol (9: i ) system is suitable for the separation of the oligoesters of the eser-diol type and a n -propanol-28% aqueous ammonia-water (70:25:5) system for the ester-hydroxy acid type. Oligoesters separated on the thin-layer chromatographic plate were sprayed with a hydroxylamine solution and then with a ferric perchlorate solution, so that purpose chelate complexes wee formed. Quantitative analysis was carried out by lifting the spots from the plate, reacting them again with the same two solutions, and, after filtration, measuring the absorption of the solution at 540 nm. The average recovery was 97%. The method could decrease the experimental errors caused by scraping off the spots, because visible spots were scraped and unreacted samples were again reacted with the same reagents." @default.
