(FR) PROCEDES DE PREPARATION DE 1,1,1-TRIS(4-HYDROXYPHENYL)ALCANES
Abstract: front page image
(EN)A method for preparing l,l,l-tris(4-hydroxyphenyl)alkanes generally comprises reacting a mixture of an aromatic hydroxy compound and a ketone in the presence of at least one ion exchange resin catalyst and optionally a co-catalyst to produce the l,l,l-tris(4-hydroxyphenyl)alkanes of formula (I).
(FR)L'invention concerne un procédé de préparation de 1,1,1-tris(4-hydroxyphényl)alcanes, ce procédé consistant de manière générale à faire réagir un mélange d'un composé hydroxylé aromatique et d'une cétone en présence d'au moins un catalyseur à base de résine échangeuse d'ions et éventuellement d'un co-catalyseur pour produire les 1,1,1-tris(4-hydroxyphényl)alcanes de formule (I).
