“…The determination of alcoholic hydroxyl compounds by the succinic anhydride method was explored in detail by Narang and Mathur (410), and the phthalization method was investigated by Nigam and coworkers (424)• Pyruvyl chloride 2,6-dinitrophenylhydrazones were employed for the identification and characterization of primary, secondary, and tertiary alcohols in a new method devised by Schwartz and Brewington (529). In further explorations of this technique they described quantitative column and qualitative thin layer chromatographic procedures for separating these derivatives (531). Severin (539) produced color tests which distinguish primary, secondary, and tertiary alcohol reaction products with A-chloro, bromo, and iodosuccinimides.…”
