Abstract: front page image
(EN)Disclosed is a method for producing 2,6-di-tert-butyl-4-mercaptophenol which comprises a step wherein bis(3,5-di-tert-butyl-4-hydroxyphenyl)polysulfide is reduced with zinc in a mixed solvent of toluene and an n-butanol. Also disclosed is a method for producing 4,4'-isopropylidinedithiobis[2,6-di-tert-butylphenol] using such a method.
(FR)La présente invention décrit une méthode de synthèse du 2,6-di-tert-butyl-4-mercaptophénol qui comprend une étape où le bis(3,5-di-tert-butyl-4-hydroxyphényl)polysulfide est réduit par le zinc dans un mélange de solvants toluène/n-butanol. La présente invention décrit également une méthode de synthèse du 4,4'-isopropylidinedithiobis[2,6-di-tert-butylphénol] en employant une méthode selon l'invention.
(JA)本発明は、ビス(3,5−ジ−tert−ブチル−4−ヒドロキシフェニル)ポリスルフィドを、トルエンとn−ブタノールとの混合溶媒中、亜鉛で還元することを含む2,6−ジ−tert−ブチル−4−メルカプトフェノールの製造方法を提供し、該方法を利用した4,4’−イソプロピリデンジチオビス[2,6−ジ−tert−ブチルフェノール]の製造方法を提供する。
