Because the olefinic hydroxyl groups are linked with olefinic carbon, so it can ionize H〓 ion and present the properties of weak acid, and so the olefinic hydroxyl groups change into the structure of alcoholate in the presence of alkali , but the structure of alcoholate may change into the structure of olefine alcohol again, after the Na〓 ions is removed, or when the pH value of its solution turn into pH. Because the structure of the olefine alcohol is not stable and is easy to isomerizate to become the structure of olefine ketone, so there appear the ca. 1730cm〓 C=O absorption peak in the IR spectra of the products.
明确指出了在C〓、C〓富勒醇中存在烯碳羟基与叔碳羟基等二类羟基，烯碳羟基由于与一个共轭体系相连，从而其羟基可以离解而呈现出弱酸的性质，因而在碱性条件下易形成烯醇钠盐的结构，当除去钠离子后或在酸性溶液中，烯醇钠盐结构转变为烯醇结构，但由于烯醇结构不如烯酮结构稳定，从而形成烯醇结构后，烯醇结构异构化为烯酮结构，因此在其产物的IR谱图上出现1730cm〓附近的C=0吸收信号。
