這類化合物在3500cm-1~3200cm-1間之O-H伸縮震動吸收頻率明顯地受分子內氫鍵的影響,有分子內氫鍵者吸收頻率較大;在1780cm-1~1640cm-1間的C=O伸縮震動吸收頻率明顯地受分子內氫鍵支配,有分子內氫鍵者吸收頻率降低,其他的取代基對C=O的吸收頻率影響較小。

Synthesis of Anthraqui none Derivatives
Author: Ying-Mei Liu, Shuenn-Jyi Sheu(Department of Chemistry, National Taiwan Normal University)
Abstract:
Fourteen anthraquinone derivatives had been synthesized via six major routes: p-chlorophenol and phthalic anhydride via the condenstion and substitution reactions led compound 1~4 ; pyrocatechol and phthalic anhydride via the condensation and substitution reactions led compound 5~6; o-cresol and phthalic anhydride via the condensation reaction led compound 7; phenol and phthalic anhydride via the condensation and substitution reactions led compound .8~10; gallic acid and benzole acid via the condensation and substitution reactions led compound 11~12; gallic acid via the self-condensation and substitution reactions led compound 13~14.
The c=o and O-H stretching vibration of these compounds were found in the regions of 1780-1640 cm-1 and 3500-3200cm-1, and the detailed differences were discussed.
