- 中文摘要: 2,4-Dinitrophenydrazones of benzaldehyde, salicyladehyde, m-hydroxybenzaldehyde, p-hydroxybenzaldehyde, p-anisaldehyde, protocatechuic aldehyde, vanillin, isovanillin, o-vanillin, heliotropin (or piperonal), syringaldehyde, and gallaldehyde trimethyl ether were prepared. Ultoaviolet and infrared absorption spectra of these hydrazones were compared from a viewpoint of variation in their hydroxylation patterns. An attempt to separate these compounds by means of Silica-gel thin layer chromatography is also described.
