isopropyl alcohol by direct hydration of propylene gas

Isopropyl alcohol

Direct hydration reacts propene and water either in gas phase or in liquid phase at high pressures in the presence of solid or supported acidic catalysts This type of process usually requires higher-purity propylene ( 90%) [16] Direct hydration is more commonly used in Europe

Direct Hydration Reacts Propene And Water Environmental

There are two routes for the hydration process: indirect hydration via the sulfuric acid process and direct hydration The former process which can use low-quality propene predominates in the USA while the latter process which requires high-purity propene is more commonly used in Europe These processes give predominantly isopropyl alcohol rather than 1-propanol because the addition of
