The cracking reaction of Ethylidene diacetate is the key step to manufacture vinyl acetate from C1 compound. The technological development is based on the study of the reaction property and the reactor, and is guided by the process simulation results.

二醋酸亚乙酯裂解反应是C1路线制醋酸乙烯的关键步骤，其工艺的开发离不开反应过程的研究和反应器的确定，而过程数学模拟可以指导过程开发。

The investigated potassium carboxylates included: monocarboxylate potassium acetate, dicarboxylate potassium tartrate (K2Tart), tricarboxylate potassium citrate (K3Cit), and tetracarboxylate dipotassium of ethylenediaminetetraacetic acid (K2EDTA). KOAc can only induce calcium oxalate monohydrate, while K3Cit and K2EDTA induce COM and calcium oxalate dihydrate. The ability of multicarboxylates to induce COD formation was increased with increasing their concentrations.

加入一元醋酸钾只生成一水草酸钙晶体；三元柠檬酸钾(K3Cit)和四元乙二胺四乙酸二钾(K2EDTA)可诱导二水草酸钙形成，且随着其浓度增加，对COD的诱导能力增加，而二元酒石酸钾(K2Tart)同时诱导了COM， COD和三水草酸钙生成。

DCA, or dichloroacetic acid, is an analogue of acetic acid in which chlorine atoms replace two of the three hydrogen atoms on the methyl group.

DCA也叫二氯乙酸或二氯醋酸，是一种类似乙酸的化合物，但乙基团上有两个氢原子被氯原子所取代。
