Double salts of 3: 6-diamino-10-alkylacridinium bases with 3: 6-diaminoacridine are prepared by interaction of a mono-salt of each base in a solvent or suspending agent. Alternatively, an acid quaternary salt may be combined with 3: 6-diaminoacridine, or the quaternary base with an acid salt of 3 : 6-diaminoacridine. Again, the acid salts of both, or one acid and one mono-salt, may be combined and the excess of acid removed by addition of a base; or both bases, or one base and one mono-salt, may be brought into reaction and the necessary amount of acid then added. The reaction is preferably effected by the aid of heat. Solvents mentioned are water, ethyl alcohol, acetone, ethylene glycol, glycerine and pyridine. The products, which are more water-soluble than their components, are useful as bactericides.
