PURPOSE:To provide the title compsn. which exhibits stable, marked effects in bacterium prevention, mold prevention, waste water treatment, rust prevention, oil reforming, and antistatic activity for fiber and plastic products and which comprises a particular ferrous ferric salt and, added thereto, a compd. of a zinc group metal. CONSTITUTION:A ferrous ferric salt compsn. comprising a ferrous ferric salt of the formula Fe3Cl8.xH2O and, added thereto, a compd. of zinc group metal [e.g., AnCl2, CdCl2, ZnSO4, CdSO4, ZnO, CdO, (CH3COO)2Zn, (CH3COO)2Cd, etc.,]. The ferrous ferric salt is prepd. by, e.g., adding KOH to conc, soln. of a mixture of a ferrous salt with a ferric salt heated to the b.p., dissolving a hydroxide deposited in hydrochloric acid and evaporating the yellow soln. over CaCl2 and conc. sulfuric acid. Incorporation of the above zinc group metal compd. into an aq. soln. of the ferrous ferric salt thus prepd. leads to the formation of the desirable ferrous ferric salt compsn. This compsn. exhibits stable, marked effects in bacterium prevention, mold prevention, waste water treatment, rush prevention, oil reforming, and antistatic activity for fiber and plastic products.
