Description
本発明は、高純度ビニレンカーボネートに関する。
ビニレンカーボネートは、リチウム二次電池用電解液の溶媒及び添加剤として有用である。
The present invention relates to high-purity vinylene carbonate.
Vinylene carbonate is useful as a solvent and an additive for an electrolytic solution for a lithium secondary battery.
ビニレンカーボネートの合成法としては、これ迄に幾つかの方法が報告されている。例えばエチレンカーボネートの塩素化で得られるクロロエチレンカーボネートの脱塩化水素による方法（Ｍ．Ｓ．Ｎｅｗｍａｎ ａｎｄ Ｒ．Ｗ．Ａｄｄｏｒ，Ｊ．Ａｍ．Ｃｈｅｍ．Ｓｏｃ．，７５，１２６３（１９５３）、Ｊ．Ａｍ．Ｃｈｅｍ．Ｓｏｃ．，７７，３７８９（１９５５））、特開平１１−１８０９７４号公報）やエチレンカーボネートの脱水素による方法（米国特許第３，４５７，２７９号公報）等が知られている。 Several methods have been reported so far for synthesizing vinylene carbonate. For example, a method by dehydrochlorination of chloroethylene carbonate obtained by chlorination of ethylene carbonate (MS Newman and RW Addor, J. Am. Chem. Soc., 75, 1263 (1953), J. Am). Chem. Soc., 77, 3789 (1955)), JP-A-11-180974), a method by dehydrogenation of ethylene carbonate (US Pat. No. 3,457,279) and the like are known.
電解液の溶媒として用いられるビニレンカーボネートについては、高品質のものが要求されるが、例えばクロロエチレンカーボネートを原料とするビニレンカーボネートについては、非常に多様な有機塩素化合物や無機塩素化合物を不純物として含有している。
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.
例えば、減圧条件での蒸留（Ｍ．Ｓ．Ｎｅｗｍａｎ ａｎｄ Ｒ．Ｗ．Ａｄｄｏｒ，Ｊ．Ａｍ．Ｃｈｅｍ．Ｓｏｃ．，７５，１２６３（１９５３）、Ｊ．Ａｍ．Ｃｈｅｍ．Ｓｏｃ．，７７，３７８９（１９５５））、融液晶析法によりビニレンカーボネートを部分的に結晶化させる操作を数回繰り返す方法（英国特許第８９９２０５号公報）とゾーンメルティングによる方法（Ｍ．Ｚｉｅｆ，Ｈ．Ｒｕｃｈ ａｎｄ Ｃ．Ｈ．Ｓｃｈｒａｍｍ，Ｊ．Ｃｈｅｍ．Ｅｄｕｃａｔｉｏｎ，４０，３５１（１９６３））及びクロロエチレンカーボネートの脱塩化水素反応をジブチルカーボネート等の高沸点溶媒中で行い、次いで蒸留する方法（特開２０００−２６４４９号公報）等が提案されている。 For example, distillation under reduced pressure conditions (MS Newman and RW Addor, J. Am. Chem. Soc., 75, 1263 (1953), J. Am. Chem. Soc., 77, 3789 (1955). )), A method in which vinylene carbonate is partially crystallized by a melt liquid crystal deposition method (UK Patent No. 899205) and a method by zone melting (M. Zief, H. Ruch and CH. Schramm, J. Chem. Education, 40, 351 (1963)) and a method in which a dehydrochlorination reaction of chloroethylene carbonate is carried out in a high boiling point solvent such as dibutyl carbonate and then distilled (Japanese Patent Laid-Open No. 2000-26449), etc. Has been proposed.
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.
本発明は、高品質のビニレンカーボネートを従来の方法よりも経済的に製造することが
できる方法を提供しようとするものである。
The present invention seeks to provide a process by which high quality vinylene carbonate can be produced more economically than conventional processes.
本発明者らは、かかる事情に鑑み鋭意検討した結果、粗ビニレンカーボネート中に不純物として含まれる塩素化合物については、極性溶媒及び／又は芳香族炭化水素溶媒に溶解すること、しかもその量が少ない場合には前記溶媒中に非極性溶媒が含まれていても塩素化合物は溶解したままであること、従って、かかる溶媒を用いて粗ビニレンカーボネートの晶析精製をすれば、不純物が製品の表面に付着したり、或いはそれ自身が固体として析出するという問題は起こらず、製品品質が向上することを見出し、本発明を完成するに至った。
即ち、本発明の要旨は、純度９９．５％以上であり、塩素化合物の含有量が全塩素量として５００ｐｐｍ以下であるビニレンカーボネート、にある。
As a result of intensive studies in view of such circumstances, the present inventors have found that the chlorine compound contained as an impurity in the crude vinylene carbonate can be dissolved in a polar solvent and / or an aromatic hydrocarbon solvent, and the amount thereof is small. Even if a non-polar solvent is contained in the solvent, the chlorine compound remains dissolved. Therefore, if the crude vinylene carbonate is purified by crystallization using such a solvent, impurities will adhere to the surface of the product. Or the problem that it precipitates as a solid does not occur, and it has been found that the product quality is improved, and the present invention has been completed.
That is, the gist of the present invention resides in vinylene carbonate having a purity of 99.5% or more and a chlorine compound content of 500 ppm or less as a total chlorine content.
本発明によれば、粗ビニレンカーボネートを極性溶媒及び／又は芳香族炭化水素溶媒を含む溶媒に溶解させ、次いでビニレンカーボネートを固定として析出させることにより、高品質のビニレンカーボネートを経済的に得ることができる。 According to the present invention, it is possible to economically obtain high-quality vinylene carbonate by dissolving crude vinylene carbonate in a solvent containing a polar solvent and / or an aromatic hydrocarbon solvent, and then precipitating vinylene carbonate as a fixed substance. it can.

結晶を更に析出又は成長させる方法としては、例えば冷却、脂肪族炭化水素のようなビニレンカーボネートの溶解度の小さい溶媒を添加する方法、冷却された溶媒を添加する方法、液体のビニレンカーボネートを添加する方法等やそれらの組合せによる方法が使用できる。

このような方法により高純度のビニレンカーボネートを得ることができる。
The precipitated solid is separated by a method such as filtration or centrifugation. If necessary, the solid surface is further washed with a suitable solvent. This solid is usually heated above its melting point to obtain vinylene carbonate as a liquid. This vinylene carbonate can be used as a product as it is, but if necessary, the residual solvent can be removed by topping or the like.
High purity vinylene carbonate can be obtained by such a method.

掻き取り翼付きの２５０Ｌ反応器に、ビニレンカーボネート（純度９８．６９％、全塩素３１６０ｐｐｍ）５０．０ｋｇとトルエン５０．０ｋｇ、ヘキサン５０．０ｋｇを仕込み撹拌しながら冷却した。１４．７℃で種晶５０ｇを添加し３０分撹拌した後、２．５時間かけて４．０℃まで冷却した。固体を濾別し、５℃のヘキサン５０ｋｇで２回洗浄し、ＶＣを固体で得た。回収率９３．３％、純度９９．９４％、全塩素１５ｐｐｍ。
Example 14
A 250 L reactor equipped with a scraping blade was charged with 50.0 kg of vinylene carbonate (purity 98.69%, total chlorine 3160 ppm), 50.0 kg of toluene, and 50.0 kg of hexane, and cooled with stirring. After adding 50 g of seed crystals at 14.7 ° C. and stirring for 30 minutes, the mixture was cooled to 4.0 ° C. over 2.5 hours. The solid was filtered off and washed twice with 50 kg of hexane at 5 ° C. to obtain VC as a solid. Recovery rate 93.3%, purity 99.94%, total chlorine 15ppm.
比較例１
ビニレンカーボネート１００ｇ（純度９９．２４％、全塩素６２７０ｐｐｍ）を４段の蒸留塔を使用し、還流比５〜１０で２回精密蒸留した。収率６９％、純度９９．８０％、全塩素量５３０ｐｐｍ。
Comparative Example 1
100 g of vinylene carbonate (purity 99.24%, total chlorine 6270 ppm) was subjected to precision distillation twice using a four-stage distillation column at a reflux ratio of 5 to 10. Yield 69%, purity 99.80%, total chlorine content 530 ppm.
