A weak acid catalyst is necessary for imine formation, which takes place by amine addition to the carbonyl group, giving a 1-aminoalcohol intermediate, followed by loss of water. It is highly soluble in water, and readily. This reaction is fairly rapid and energetic at high concentrations, in large part due to the high affinity of calcium ions for chloride ions. This compound is relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). Lime, sodium carbonate (soda ash), and/or sodium hydroxide (caustic soda) are added to water to convert soluble calcium and magnesium hardness to insoluble calcium carbonate and magnesium hydroxide in a contact vessel for 60-90 min [10, 12, 14]. It most commonly occurs as a crystaline heptahydrate which readily effloresces to form a white powder, the monohydrate. Sodium Carbonate , known as soda ash, is a very important industrial chemical.
