CALCIUM HYDROXIDE PRODUCTION PROCESS Russian patent published in 2004 - IPC

Abstract RU 2225358 C1

FIELD: industrial inorganic synthesis. SUBSTANCE: calcium hydroxide is produced via hydration of lime in presence of organic additive followed by separating desired product. Hydration involves preliminarily ground lime passing through screen 0.315 mm. Organic additive utilized is oxyethylated monoalkylphenols based on propylene trimers or products of treatment of mono- and dialkylphenol mixture with ethylene oxide (OP-7 or OP-10). EFFECT: increased yield of desired product, increased its purity, and enhanced dispersity and simplified recovery of desired product. 4 cl, 1 dwg, 1 tbl
