| abstract | 544,049. Preserving wood. BOLIDENS GRUVAKTIEBOLAG. Sept. 9, 1940, No. 14025. Convention date, Sept. 9, 1939. [Class 140] Wood is preserved by impregnation with an aqueous solution or paste comprising a ferrous salt and arsenic acid in substantially equimolecular proportions, so that on drying the arsenic acid is wholly precipitated as ferric arsenate. The ferrous salt may be ferrous sulphate, chloride or acetate. A reducing agent such as a mixture of iron powder and sulphuric acid may be added to stabilize the solution, which may also contain tartaric or oxalic acid or their alkaline salts. The solution may contain 0.66 to 1.50 mols. of ferrous salt per mol. of arsenic acid. |
