Patent

CA 2379042

The invention relates to a process for the preparation of an aromatic bisoxazoline in which, in a first step, an aromatic carboxylic acid or an ester hereof reacts with an alkanolamine, after which the hydroxyalkylamide obtained is in a second step converted into an aromatic bisoxazoline in the presence of a catalyst. The catalyst is phosphinic acid, a (C1-C26) alkyl phosphinic acid, a (C6-C20) aryl phosphinic acid or an ester or an anhydride derived from one of these acids.

L'invention porte sur un procédé de préparation d'un bisoxazoline aromatique dans lequel, dans une première étape, un acide carboxylique aromatique ou un ester de celui-ci réagit avec un alcanolamine, puis l'hydroxyalkylamide obtenu est converti dans une seconde étape en un bisoxazoline aromatique en présence d'un catalyseur. Le catalyseur est un acide phosphinique, un acide phosphinique (C¿1?-C¿26?) alkyle, un acide phosphinique (C¿6?-C¿20?) aryle ou un ester ou un anhydride dérivé d'un de ces acides.
