Dünnschichtchromatographie der Chloro-Cyclophosphazene. I. Zur Trennung der Oligomeren Chloro-Cyclophosphazene [NPCL2]n (n = 3 – 7)

Thin Layer Chromatography of Chloro-Cyclophosphazenes I. Separation of Oligomers MNCL₂]_n (n = 3 – 7) This paper presents a separation study of cyclo-chlorophosphazenes by means of thin layer chromatography on silica gel and a new sensitive method of detection of these separated substances. The chromatographic behavior of oligomers (n = 3–7) of the homologic series NPCL₂]_n was experimentally studied. The R_f values of the substances were correlated with their molecular weights. As a result a Quasi-linear function was obtained for the members with n = 4–7.
