Process for the production of alkalithiocyanate |
摘要 |
A process for the production of solid or dissolved alkalithiocyanate by reaction of dissolved alkalicyanide with an alcoholic sulphur suspension at the boiling point of the alcohol. The alcohol is distilled off as an azeotrope and the unreacted sulphur is separated. For the isolation of the solid product, a pH of 5-9 is adjusted in the solution obtained and thus a crystallization or evaporation is carried out.
