醋酸是一种重要的有机化工产品,主要用于醋酸乙烯(VAM)、醋酸酯、醋酸酐、对苯二甲酸(PTA)、氯醋酸、双乙烯酮等产品的生产,是合成纤维、胶粘剂、医药、染料和农药的重要原料。此外,它还是优良的有机溶剂,在化工、轻纺、塑料、医药、橡胶以及染料等行业有着十分广泛的用途。目前,醋酸的生产方法主要有轻烃液相氧化法、乙醛氧化法、乙烯直接氧化法、乙烷选择性催化氧化(联产醋酸和乙烯)法和甲醇羰基合成法。其中甲醇 Acetic acid is an important organic chemical product mainly used in the production of VAM, acetate, acetic anhydride, terephthalic acid (PTA), chloroacetic acid, diketene and other products. It is a synthetic fiber, adhesive, medicine, Dyes and pesticides, an important raw material. In addition, it is an excellent organic solvent and has a wide range of uses in the chemical, textile, plastics, pharmaceuticals, rubber and dye industries. Currently, acetic acid production methods are light hydrocarbon liquid phase oxidation, acetaldehyde oxidation, ethylene direct oxidation, ethane selective catalytic oxidation (co-production of acetic acid and ethylene) and methanol carbonyl synthesis. Among them, methanol
