How is isopropanol synthesised?
The most popular way to produce isopropanol involves a reaction between propene and water (indirect and direct hydration reaction) or via hydrogenation of acetone.
- Indirect hydration: In this case, propene reacts with sulphuric acid to form sulphate esters and their subsequent hydrolysis produces isopropanol. This solution is finally distilled to separate isopropanol from the other products of the reaction. This is a common method used in the USA and can use low-quality propene. By-product diisopropyl can be recycled back and hydrolysed again to generate isopropanol, therefore increasing the overall efficiency of the method.
- Direct hydration: In this case, the reaction is directly between propene and water, at high pressure and supported by acidic catalysts. This method requires high-quality propene (>90% purity) and is more commonly used in Europe. This method also requires distillation to isolate isopropanol from other reaction by-products.
- Hydrogenation of acetone: This process involves hydrogenation of acetone in the presence of a mixture of copper and chromium oxide to synthesise isopropanol. This method is often linked to excess acetone production via the cumene process.
