| titleOfInvention | An improved method for producing hydrocyanic acid from salts or compounds of sulphocyanic acid |
| abstract | Sulphocyanic acid compounds, salts, or derivatives, such as esters or compounds with amines (including pyridine) are oxidized by air or oxygen to obtain hydrocyanic acid by mixing the sulphocyanogen compound in the form of vapour or spray wtih the oxygen-containing gas at a suitable temperature, for instance 350-750 DEG C., the reaction being effected for instance by passing the mixture through tubes of clay, silica, iron, aluminium &c. the rough or metallic surface having a catalytic effect. The sulphocyanogen ocmpounds, if not volatile, may be atomized by distilling a solution in superheated steam, by passing superheated steam with melted sulphocyanide, by running a solution into a vessel heated to a high temperature so as to cause sudden evaporation, or by injecting superheated steam or air or both. In an example, a solution of ammonium sulphocyanide is admitted drop by drop into a vessel heated to about 350 DEG C., and air, which may be preheated, is introduced. The gases are led through a quartz tube containing pieces of quartz and heated to 500 DEG C. |
