dicarboxylic acid circulation

Bis(tributyltin) esters of glutaric acid were synthesized by the reaction of disodium dicarboxylates with the tributyltin chloride in 1:2 molar ratio and characterized by elemental analysis, IR and 1H NMR.

用三丁基氯化锡与戊二羧酸二钠以2:1摩尔比反应,合成了双（三丁基锡）戊二羧酸酯,并用元素分析、红外光谱、核磁共振氢谱及X-射线单晶衍射进行了表征和结构测定。

The diisobutyl dicarboxylate was preparaed by using dicarboxylic acid and isobutanol as material and sulfuric acid as catalyst.

以二羧酸和异丁醇为原料，用硫酸作催化剂，合成二羧酸二异丁酯。
