Patent GB-180118-A (GB)
Title: An improved method of generating hydrocyanic acid
IPC: C01C3/00
Filed: 1921-03-15
Abstract: Hydrocyanic acid is generated, for instance for fumigating plants by mixing a cyanide such as sodium cyanide with an anhydrous or partly dehydrated salt such as magnesium or aluminium chloride or sulphate such that the metal forms an unstable cyanide and the hydration of the salt liberates enough heat to expel the hydrocyanic acid.  The mixture is stable when dry but liberates hydrocyanic acid on addition of water. Additional heat may be applied externally if necessary. Alternatively when the cyanide is used in solution, or the metal salt is hydrated, a salt such as calcium chloride may be added to add the necessary heat.

Title: Improvements in the manufacture and production of formic acid
IPC: C07C51/06
Filed: 1937-03-23
Abstract: Formic acid is produced by reacting formamide with water and mineral acid, preferably sulphuric acid, at above 85 DEG  C. Equivalent proportions of the reacting components may be run continuously into heated formic acid while distilling off formic acid as rapidly as it is formed.  The ammonium salt of the mineral acid is precipitated and can be separated by centrifuging or filtering.  At above 60 DEG  C. the separation is practically complete, traces of formic acid being removed by blowing with hot air or other gases or vapours, and reclaimed by washing the gases or vapours with formamide.  Ammonium sulphate is obtained in granular form suitable for a fertilizer.  In an example, the reactants are added to boiling formic acid, the temperature gradually rising to about 125 DEG  C., pressure being atmospheric. Reduced or increased pressures may be employed.  Part of the contents of the reaction vessel is treated periodically in a heated centrifuge arranged beneath it, the mother liquor being returned.ALSO:Ammonium salts are produced by reacting formamide with water and mineral acid, preferably sulphuric acid, at above 85 DEG C.
