ABSTRACT:
Highly pure aromatic polyfunctional cyanic acid esters having a high stability in storage and being extraordinary suitable for use as starting compound for the production of plastics by cyclopoly-trimerization are obtained by a special process. Alkaline earth and/or alkali metal salts of polyfunctional aromatic hydroxy compounds said alkaline earth and/or alkali metal compound capable of phenolate formation are used in excess of up to 0.1 mol per mol of aromatic hydroxy group are reacted with an excess of cyanogen halide. The cyanogen halide excess comprises up to 1 mol per mol of aromatic hydroxy group plus excess mol of the metal compound used for salt production.
