    摘要： An improved process for the production of cyanogen chloride is disclosed according to which liquid hydrocyanic acid and gaseous chlorine are reacted in an aqueous medium. The liquid hydrocyanic acid and chlorine are introduced into a column-shaped reactor via at least one two-component nozzle. The reaction mixture is removed at the head of the column-shaped reactor. Preferably, the hydrocyanic acid is in liquid form and the chlorine is in gaseous form. By the process disclosed, quantitative yields of cyanogen chloride are obtained separately from aqueous solutions of hydrochloric acid of a strength suitable for commercial use.

    摘要： A process for the tertiary dealkylation of a tertiary alkyl containing m- and/or p-cresol wherein a tertiary alkyl containing m- and/or p-cresol is continously introduced into a reaction vessel with a small amount of sulfuric acid or an quivalent amount of a sulfonic acid and the reaction vessel contains a high concentration of m- and/or p-cresol or a high boiling phenol which under the prevailing reaction conditions is not substantially vaporized from the reaction mixture. The reaction mixture is maintained at a temperature of no greater than 230.degree. C. The reaction products are withdrawn continuously from the reactor (and separated into its components) and at the same time a small amount of the reaction mixture being withdrawn intermittently or continously from the reactor.
