Abstract:
(EN) Provided is a method for producing a 1,1,2,2-tetrakis(4-hydroxyphenyl)ethane compound, the method comprising: in a reaction solvent, reacting phenols with glyoxal in the presence of an acid catalyst to obtain a mixture including the 1,1,2,2-tetrakis(4-hydroxyphenyl)ethane compound, isomers thereof, and phenols; and extracting the 1,1,2,2-tetrakis(4-hydroxyphenyl)ethane compound from the mixture using tetrahydrofuran or acetonitrile.
(FR) L'invention concerne un procédé de production d'un composé de 1,1,2,2-tétrakis (4-hydroxyphényl) éthane, le procédé comprend : dans un solvant de réaction, faire réagir du phénols avec du glyoxal en présence d'un catalyseur acide pour obtenir un mélange comprenant le composé 1,1,2,2-tétrakis (4-hydroxyphényl) éthane, des isomères de celui-ci et des phénols; et extraire le composé 1,1,2,2-tétrakis (4-hydroxyphényl) éthane du mélange à l'aide du tétrahydrofurane ou d'acétonitrile.
(JA) 酸触媒の存在下に反応溶媒中でフェノール類とグリオキザールとを反応させて1,1,2,2-テトラキス(4-ヒドロキシフェニル)エタン化合物およびその異性体並びにフェノール類を含む混合物を得、得られた混合物から1,1,2,2-テトラキス(4-ヒドロキシフェニル)エタン化合物をテトラヒドロフランまたはアセトニトリルを用いて抽出することを有する、1,1,2,2-テトラキス(4-ヒドロキシフェニル)エタン化合物の製造方法。
