Abstract
Spectrophotometric and electroanalytical studies indicate that one of the formyl groups of terephthalaldehyde in aqueous solution is present in about 23% as a geminal diol. Stronger covalent hydration of CHO in terephthalaldehyde than in p-nitrobenzaldehyde is attributed to a strong resonance interaction between the two formyl groups.
摘要
分光光度法和电分析研究表明，对苯二甲醛在水溶液中的一个甲酰基约23%以偕二醇的形式存在。对苯二甲醛中CHO的共价水合作用比对硝基苯甲醛中的更强，这归因于两个甲酰基之间强烈的共振相互作用。
