ABSTRACT:
According to this method for the adsorptive extraction of hydrocarbons from aqueous solutions of hydrocyanic acid, the initial solutions containing 1 to 50 wt. % hydrocyanic acid and 2 to 1000 wt. ppm aliphatic and/or aromatic hydrocarbons, the latter having 6 to 30 C atoms each, are passed, preferably continuously, at temperatures between 2 and 50.degree. C. and at a maximum flow velocity of 500 m/h through a fixed-bed, activated-carbon adsorber whose interior surface is preferably>100 m.sup.2 /kg. In this way it is possible to quantitatively free aqueous solutions of hydrocyanic acid from hydrocarbons, in particular from benzene, with means of relatively low technical complexity.
