摘要：the esters of aromatic hydroxycarboxylic acids of the general formula (1).(r1\―coo) n\―ar\―x - coch\ \ \ \ \  (1) areproduced by a method in which in a first step, an aromatic hydroxycarbons\äure ofthe general formula (2) (ho) n\―ar\―x - cooh\ \ \ \ \  (2)in aqueous solution in the presence of water soluble or water mischbarer base 3 -chlorine - or 3 - brompropions\äurehalogenid to basensalz esters aromatichydroxycarboxylic acids of the general formula (1) is esterified in a second step, thenational basensalz of esters atischer hydroxycarboxylic acids of the general formula (1)by the addition of acid to free esters, aromaticr hydroxycarboxylic acids of the generalformula (1) is implemented. in the above general formula (1) and (2) r1eine 2 chlorethyl -,2 - bromethyl or a ethenylgruppe, from whole number in the value of 1, 2 or 3, areinsubstituiertes or unsubstituiertes arylen or heteroarylen undxeine direct bonding or aethenylgruppe mean.
