Abstract (en)

[origin: WO2006131467A2] The invention relates to a method for producing a solution of hydrocyanic acid salts, said method comprising the following steps: a) a raw gas containing hydrocyanic acid is produced by dehydrating formamide to a formamide transformation percentage of = 97; b) optionally the raw gas obtained in step a) is subjected to acid washing; c) the raw gas obtained in step a) or optionally step b) is then reacted with an aqueous solution of a hydroxide M(OH)<SUB>x</SUB>, where M is selected from the group of alkali metals and earth alkali metals and x represents 1 or 2 according to the oxidation number of M.
