Claims (7)
- 1.水、ベンゼンジアゾニウム化合物およびヒドロキノンの入っている混合物を 、この混合物のpHを約3〜約9に維持しながら、約0℃〜200℃の温度で反 応させる、ことから成るフェニルヒドロキノンの合成方法。
- 2.該混合物がまた、ヒドロキノンに対して良好でない溶媒であるところのフェ ニルヒドロキノン用水不混和性溶媒を含有しており、そしてこの混合物を激しく 混合することで、水と該水不混和性溶媒との2相混合物を生じさせ、そしてこの 反応の終了時に該フェニルヒドロキノンを該溶媒中に溶解させる請求の範囲1の 方法。
- 3.該水不混和性溶媒がハロゲン化炭化水素溶媒である請求の範囲2の方法。
- 4.該ハロゲン化炭化水素溶媒が塩化メチレン、1,1,2−トリクロロエタン 、1,1,1−トリクロロエタン、クロロベンゼンおよび0−ジクロロベンゼン から成る群から選択される請求の範囲3の方法。
- 5.該ベンゼンジアゾニウム化合物が硫酸水素ベンゼンジアゾニウムおよび塩化 ベンゼンジアゾニウムから成る群から選択される請求の範囲1の方法。
- 6.水酸化アンモニウム、水酸化ナトリウム、四重ホウ酸ナトリウム、燐酸水素 ナトリウム、および酢酸ナトリウムから成る群から選択される1員を添加するこ とによって該pHを保持する請求の範囲1の方法。
- 7.存在しているヒドロキノンの該量が、モルを基準にして、ベンゼンジアゾニ ウム化合物の量よりも多い請求の範囲1の方法。
