摘要：
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.
