The acidity constants of some synthetic derivatives of 9,10-anthraquinone and 9-anthrone in methanol-water mixtures at 25 degrees have been determined spectrophotometrically. A linear reverse relationship is observed between pK(a1) of all acids and the mole fraction of methanol. The influence of substituents in the molecular structure on the ionization constants is discussed.
通过分光光度法测定了9,10 - 蒽醌和9 - 蒽酮的一些合成衍生物在25℃下于甲醇 - 水混合溶剂中的酸度常数。观察到所有酸的pK(a1)与甲醇的摩尔分数之间存在线性反比关系。讨论了分子结构中取代基对电离常数的影响。
