In this fashion the four entering carbons of two acetyl - coa molecules are conserved to form one 4 - carbon dicarboxylic acid 用这种方式，由两个乙酰辅酶a引进的四个碳，转变成一个四碳二羧酸。
The reaction pathways were proposed as follows : firstly , hydroxylation of aromatic ring , then ring cleavage forming dicarboxylic acid and eventually oxidation to inorganic carbon 其机理为：首先是苯环羟基化，然后环破裂生成二元羧酸，最后二元羧酸氧化降解为二氧化碳和水。
A review on application of monohydrated sodium bisulfate as catalyst in synthesis of ester , such as monocarboxylic esters , dicarboxylic esters , chloroacetates , hydroxycarboxylic esters , aromatic esters and the reusability of sodium bisulfate with 摘要介绍了一水硫酸氢钠在催化合成酯（如一元羧酸酯、二元羧酸酯、氯乙酸酯、羟基酸脂、芳香酸酯）中的应用及其重复催化性能。
