- the present invention relates to a method for producing an epoxy compound.
- Epoxy compounds are used in various applications by utilizing the oxirane ring opening of 1,2-epoxide.
- bisphenol A-type epoxy resins and novolac-type epoxy resins are frequently used as semiconductor sealing materials because they are excellent in mass productivity, cost, heat resistance, water resistance, and the like.
- Examples of a method for obtaining an epoxy compound by oxidizing an olefin include, for example, a method using a heavy metal compound, nitric acid, m-chloroperbenzoic acid or the like as an oxidant, and industrially, such as peracetic acid or performic acid.

- Patent Document 3 a method of reacting olefins with hydrogen peroxide in the presence of tungsten oxide, quaternary ammonium hydrogens
- Non-Patent Document 2 a method using acetonitrile has been known for a long time (refer to Non-Patent Document 2 below).
- Epoxidation by this method is a mild reaction compared to the conventional method, and the reaction is carried out under basic conditions, so that the generated epoxy groups are less decomposed.
- white solid acetamide is generated as a by-product, and it is difficult to separate and remove this acetamide from the target product (epoxy compound). This is because, for example, since acetamide and the target product are both organic substances, they cannot be removed by washing if the solvent is selected incorrectly, and are difficult to purify by distillation because they are solid at room temperature. This is because it is difficult to scale up.
- Non-Patent Document 2 uses an alcohol-water type reaction solvent, when the solvent substitution is performed as a pretreatment for extracting an epoxy compound as a target product into an organic solvent, an excessive amount is used.
- the reaction solution must be concentrated while hydrogen oxide remains, and when using hydrogen peroxide-derived organic peroxides such as methanol as a solvent, there is a risk of concentrating methyl peroxide. This is a very dangerous way to upgrade.

Thereafter, 150 g of toluene was added and extraction operation was performed. However, acetamide remained undissolved in the aqueous layer, and separation was very difficult.
- Example 1 Since the concentration operation was performed with hydrogen peroxide remaining, there was a danger of concentrating the organic peroxide, which was very dangerous. Further, the separation performance and operability of Example 1 were superior.
- Example 2 After reacting under the same reaction conditions as in Example 1 (hydrogen peroxide concentration 0.5%), 200 g of 5% aqueous sodium sulfite solution and 200 g of toluene were added and stirred while cooling in a water bath. At this time, a large amount of white solid precipitated, and the organic layer and the aqueous layer could not be separated cleanly.

[実施例1]
温度計及び冷却管を取り付けた1Lの4口フラスコに1,4-シクロヘキサンジメタノールジアリルエーテル150.0g(0.67mol)、アセトニトリル109.8g(2.67mol)、炭酸カリウム27.7g(0.2mol)、及びエタノール200gを加え、室温で攪拌した。その後、45%過酸化水素水溶液101.1g(1.34mol)を滴下ロートで、約3時間かけて滴下し、反応熱を利用し、35~25℃を保つように水浴を利用して温度を調節した。滴下後、約2時間、35~25℃を保ちながら攪拌を続け、再び45%過酸化水素水溶液75.8g(1.00mol)を滴下ロートで、約2時間かけて滴下し、35~25℃を保ちながら反応させた。その後、約24時間反応させ、攪拌を終了させた。この時、反応液の過酸化水素濃度は、0.5%であった。その後、水200g及びトルエン200gを反応液に加え、40℃で加熱し、攪拌した。析出した全てのアセトアミドが溶解したことを確認した後、容器から分液ロートに移し、水層を取り除いた。この時の水層の過酸化水素濃度は1.5%であり、水層の方にほとんどの過酸化水素が溶解していた。その後、有機層を5%亜硫酸ナトリウム水溶液100gで3回洗浄し、次いで水100gで2回洗浄し、洗浄後の廃水の過酸化水素濃度が検出限界以下であることをヨウ素滴定法により確認し、有機層からの過酸化水素の溶出がないことを確認した。その後、エバポレーター、真空ポンプにより留去し、目的とするエポキシ化合物を得た。
実施例1と同様の反応条件で反応させた後(過酸化水素濃度0.5%)、1L一口ナスフラスコに移し、エバポレーターを用いて60mmHg、35~40℃で濃縮を行い、水との相溶性のあるエタノール及び未反応のアセトニトリルを留去した。その後、トルエン150gを加え、抽出操作を行ったが、アセトアミドが水層に溶け残っており、分離が非常に難しかった。その後、有機層のみを5%亜硫酸ナトリウム水溶液100gで3回洗浄し、次いで水100gで2回洗浄し、洗浄後の廃水の過酸化水素濃度が検出限界以下であることをヨウ素滴定法により確認し、有機層からの過酸化水素の溶出がないことを確認した。その後、エバポレーター、真空ポンプにより留去し、目的とするエポキシ化合物を得た。実施例1に比べ、過酸化水素が残留したまま濃縮操作を行うため、有機過酸化物を濃縮する危険があり、非常に危険であった。また、分離性及び操作性も実施例1の方が優れていた。
実施例1と同様の反応条件で反応させた後(過酸化水素濃度0.5%)、水浴で冷却しながら5%亜硫酸ナトリウム水溶液を200gとトルエン200gを加え、攪拌した。この時、白色固体が大量に析出してしまい、有機層と水層を綺麗に分離することができなかった。実施例1に比べると、濃縮前に還元処理することはできたが、副生成物のアセトアミドの分離に難があり、スケールアップなどを考えると現実的ではなかった。
