Dünnschichtchromatographische untersuchungen von organosiliciumverbindungen

Chromatography

“…Urea, thiourea, dicyanodiamide, biuret, and nitroguanidine have been separated by automatic liquid chromatography and detected by thermal energy (314)• Qualitative identification of the reaction products following hydrogenation of quinoline has been accomplished by liquid-solid column chromatography ments can be separated from naturally occurring tocopherols by TLC and saponification, followed by a final separation by thin-layer chromatography on silica gel GF254; the final product is eluted and determined colorimetrically (300). Commercial food emulsifiers (Span) can be identified by TLC (244) Organosilicon compounds have been studied by TLC (120,446) and silicon polymers by paper chromatography (293).…”
