Title (EN) PRODUCTION METHOD FOR BENZENEDIMETHANOL COMPOUND
(FR) PROCEDE DE PRODUCTION D'UN COMPOSE BENZENEDIMETHANOL
Abstract: front page image
(EN)To provide a novel method for producing a fluorinated benzenedimethanol compound useful as a starting material or an intermediate in the production of agricultural or medicinal chemicals in an industrially advantageous manner. A method for producing a fluorinated benzene-dimethanol compound according to the present invention comprises the steps of reducing the nitrile groups of a fluorinated benzenedinitrile compound to obtain a fluorinated xylylenediamine compound and then converting the aminomethyl groups of the fluorinated xylylenediamine compound into hydroxymethyl groups.
(FR)L'invention concerne un nouveau procédé de production d'un composé benzènediméthanol fluoré utile en tant que produit de départ ou intermédiaire dans la production d'agents chimiques agricoles ou médicaux, d'une manière avantageuse sur le plan industriel. L'invention concerne également un procédé de production d'un composé benzènediméthanol fluoré, qui consiste à réduire les groupes nitrile d'un composé benzènedinitrile fluoré afin d'obtenir un composé xylylènediamine fluoré puis à transformer les groupes aminométhyle du composé xylylènediamine en groupes hydroxyméthyle.
