Abstract
Salts are prepared by reacting thiocyanic acid and 2,4-diaminoazobenzene. In examples: (1) the base, dissolved in chloroform or other suitable solvent, is treated with aqueous thiocyanic acid and the precipitate is re-crystallized from ethyl alcohol; (2) the base is suspended in a 5 per cent aqueous thiocyanic acid solution and the resulting salt is purified as in (1). The single or double thiocyanate is formed depending on the relative quantities of reagents.
