Process for producing a calcium hydroxide compound

A process of producing calcium hydroxide, which process comprises reacting an aqueous solution of a water-soluble calcium salt with an aqueous solution of an alkali metal hydroxide in the presence of an additive. In particular, aqueous solutions of calcium chloride or calcium nitrate are reacted wit...

Beschreibung
Zusammenfassung:A process of producing calcium hydroxide, which process comprises reacting an aqueous solution of a water-soluble calcium salt with an aqueous solution of an alkali metal hydroxide in the presence of an additive. In particular, aqueous solutions of calcium chloride or calcium nitrate are reacted with aqueous solutions of sodium hydroxide or potassium hydroxide in the presence of a silicon-based compound, a phosphorus-based compound, an aluminium-based compound, an inorganic acid or an organic acid as additive.
