| titleOfInvention | Preparation method of cyanogen phenylsulfonyl |
| abstract | The invention discloses a preparation method of cyanogen phenylsulfonyl, which belongs to the technical field of chemical industry. In the method, under a condition without solvent, potassium ferrocyanide and benzene sulfonyl chloride are mixed according to the molar ratio of 1:4-1:5 and are reacted for 1-2 hours at the temperature of 150-160 DEG C, and the cyanogen phenylsulfonyl is obtained through column chromatography separation and drying. In the method, cheap, avirulent and harmless potassium ferrocyanide which is easy to obtain is adopted as a cyaniding agent, the synthesis process is carried out under the condition without solvent, and environment and safety pressure caused by the conventional method is avoided; and simultaneously, the cost of the raw material is low, the process is simple, and the method is convenient to operate and creates a good condition for industrialized scale production. |
