Abstract
(EN) The present invention addresses the problem of providing a novel production method that has a high reaction selectivity for a tetrakisphenol compound in a reaction between a phenol and a 4,4'-diacylbiphenyl. As a means for solving this problem, the present invention provides a method of producing a tetrakisphenol compound represented by formula (3), said method being characterized by comprising reacting a phenol represented by formula (1) with a 4,4'-diacylbiphenyl represented by formula (2) in the presence of a specific alkanesulfonic acid.
(FR) La présente invention aborde le problème de la fourniture d'un nouveau procédé de production qui a une sélectivité de réaction élevée pour un composé de tétrakisphénol dans une réaction entre un phénol et un 4,4'-diacylbiphényl. La solution selon la présente invention porte sur un procédé de production d'un composé de tétrakisphénol représenté par la formule (3), ledit procédé étant caractérisé en ce qu'il comprend la réaction d'un phénol représenté par la formule (1) avec un 4,4'-diacylbiphényl représenté par la formule (2) en présence d'un acide alcanesulfonique spécifique.
