Current Method of Industrial Synthesis
Nowadays, caustic soda – also known as sodium hydroxide (NaOH) – is traditionally synthesised via the chloralkali process (electrolytic reaction). Pure sodium hydroxide is obtained after removal of by-product chlorine gas. Following a final evaporation step, caustic soda is sold in flakes, pearls or powder.
The chloralkali method is used by most large companies, but other reactions have been used in the past. The first large-scale method to produce caustic soda involved a reaction between insoluble sodium carbonate (Na2CO3) and soluble calcium hydroxide (Ca(OH)2). This procedure was known as causticizing. In chemical terms, this type of reaction is called a metathesis reaction, involving a double replacement.
Ca(OH)2(aq) Na2CO3(s) → CaCO3↓ 2NaOH(aq)
Caustic soda can be produced by many other methods, most of which not commercially viable and only used in an academic setting to demonstrate certain properties to students. One example is the reaction with sodium metal and water, producing caustic soda and hydrogen gas, which is used to show how reactive alkali metals are.
