本文用光谱法研究了在硫酸和高氯酸溶液中几种氰碳阴离子的可逆质子化反应。一个指示剂酸度功能，-，基于此质子化，可以设置为酸溶液高达~ 12 M和pAV的氰基酸确定。H-功能非常类似于H 0（基于中性碱的质子化），在较低浓度（5 M或更低）下显示出基于电荷类型预期的差异，而在5 M以上时，它往往与H 0平行。氰碳酸的强度与阴离子共振结构的稳定性和蛋白质化形式的共振可能性有关。许多酸的质子化位置可以从紫外光谱推断出来。较强的氰碳酸形成固体二水合物，如紫外光谱所示，其被电离。
The reversible protonations of a number of cyanocarbon anions have been studied spectroscopically in sulfuric and perchloric acid solutions. An indicator acidity function,-, based on this protonation can be set up for acid solutions up to~ 12 M and pAVs of the cyanocarbon acids determined. The H-function is very similar to H0 (based on protonation of neutral bases) showing differences at lower concentrations (5 M or less) expected on the basis of charge type and above 5 M it tends to parallel H0. The strengths of the cyanocarbon acids can be corre-lated with the favorability of resonance structures of the anions and resonance possibilities in the proteiyited form. The positions of protonation for many of the acids can be inferred from the ultraviolet spectra. The stronger cyanocarbon acids form solid dihydrates which are ionized as shown by the ultraviolet spectra.
