Technical background

Isopropanol is an important chemical product and raw material, mainly used in pharmaceutical, cosmetics, plastics, spices, coatings and so on. Isopropanol is widely used as solvent or extraction agent in the pharmaceutical industry. Isopropanol can form azeotrope with water (12.6wt% water content). The traditional production and recovery of isopropanol adopts azeotrope distillation and extraction process, which has high energy consumption and serious pollution. Pervaporation technology can significantly improve separation efficiency and reduce process energy consumption.
