Details

[Application] Potassium cyanate can be used in organic synthesis, making hypnotics, herbicides, etc.

[Preparation] ErnerW uses potassium carbonate and urea as raw materials and sulfoxide or sulfone as solvent to synthesize potassium cyanate. The feature of the invention is the use of solvents with strong dissolving ability for urea and potassium carbonate, such as methyl ethyl sulfoxide, diethyl sulfoxide and the like. In ErnerW's patent example, 5mol of potassium carbonate and 13mol of urea are dissolved in 4.0 methyl ethyl sulfoxide, the reaction is heated and stirred with nitrogen, the reaction temperature rises to 180°C within 1 hour, and there is ammonia and 24.0c478 water vapor. The carbon dioxide overflows. After 0.25h, the temperature rises to 195℃. At this time, take a sample from the reactor and use barium nitrate to check that there is no carbonate. The reaction can be terminated. The product is cooled to room temperature, filtered, and Wash with water and ethanol to obtain 10 mol parts of potassium cyanate, with a yield of 90%.
