FIELD: industrial inorganic synthesis. SUBSTANCE: calcium hydroxide is produced via hydration of lime in presence of organic additive followed by recovering desired product. Starting material is limestone flour preliminarily fired at 950-1050 C. 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 |
