Abstract: Isopropyl alcohol is a widely used organic solvent and chemical raw material. The indirect propylene hydration method, the direct propylenehydration method, and the acetone hydrogenation method are mainly used for isopropyl alcohol production. This paper introduces different production methodsand their advantages and disadvantages. It is considered that PetroChina Jinzhou Petrochemical Company is competitive in terms of production technology,and it should adopt measures to reduce energy consumption of facilities, reduce unit consumption of propylene, optimize reaction and refining sectors toenhance its selectivity, conversion rate and yield of products, and enable facilities to reach international advanced level in the same industry.
