SICCATIVE PRODUCTION PROCESS Russian patent published in 2001 - IPC

Abstract RU 2177020 C2

FIELD: varnish-and-paint industry. SUBSTANCE: siccative is prepared by saponification of carboxylic acids, in particular flotation goudron, which is vat residue of fatty acid oxidation column from synthetic fatty acid production. Acid number of raw material is 50-70 mg KOH. Saponification is carried out with aqueous alkali solution at 80-100 C. Resulting solution is treated with siccative metal salt solution, in particular electrochemical manganese precipitation waste containing aqueous solution of manganese salts with 29.9-42.96% principal substance content in presence of hydrocarbon solvent. EFFECT: extended source of raw materials. 1 tbl, 6 ex
