このため、粗ビニレンカーボネートの精製方法についても、今迄に幾つかの方法が提案されている。
The vinylene carbonate used as the solvent for the electrolytic solution is required to have a high quality. For example, vinylene carbonate using chloroethylene carbonate as a raw material contains a wide variety of organic chlorine compounds and inorganic chlorine compounds as impurities. doing.
For this reason, several methods have been proposed so far for the purification of crude vinylene carbonate.

しかしながら、蒸留による精製法の場合、沸点がビニレンカーボネートに近い有機塩素化合物が製品中に不純物として混入するために品質的に満足できるものではない。
また、クロロエチレンカーボネートの脱塩化水素反応を高沸点溶媒中で行う方法については、高価な溶媒の回収が容易ではなく、工業的に満足できるものではない。
一方、融液晶析による方法については、高品質の製品を得ようとすれば、回収率を低くしなければならず、経済的に満足できるものではない。
However, in the case of the purification method by distillation, an organic chlorine compound having a boiling point close to that of vinylene carbonate is mixed in as an impurity in the product, which is not satisfactory in terms of quality.
Moreover, about the method of performing the dehydrochlorination reaction of a chloroethylene carbonate in a high boiling-point solvent, collection | recovery of an expensive solvent is not easy and is not industrially satisfactory.
On the other hand, with respect to the method by melt liquid crystal deposition, if a high-quality product is to be obtained, the recovery rate must be lowered, which is not economically satisfactory.

After stirring at 5 ° C for 1 hour, stirring was stopped and the mixture was allowed to stand at -5 ° C for 12 hours. The solid was separated by filtration, washed twice with hexane at 5 ° C., and then melted by heating to recover the liquid. The results are shown in Table 2 below.
