    Abstract: A process for the preparation of an aromatic cyanate which comprises (a) preparing in situ a cyanogen chloride by contacting a solution of chlorine in a chlorinated hydrocarbon with an aqueous solution of an alkali metal cyanide at a temperature of 0.degree. C. or below under conditions such that a cyanogen chloride is prepared; (b) physically separating the chlorinated hydrocarbon in which the cyanogen chloride is dissolved from the aqueous layer in which an alkali metal chloride salt is dissolved; and (c) contacting the cyanogen chloride dissolved in the chlorinated hydrocarbon with a hydroxy-substituted aromatic compound dissolved in a chlorinated hydrocarbon, a secondary alcohol or a tertiary alcohol, in the presence of a tertiary amine at a temperature of about 0.degree. C. or less under conditions such that a polyaromatic cyanate is prepared.
