乙醛、丙酮是十八种重要的基本有机化工产品之一,其生产方法较多,目前以纯乙烯、丙烯钯催化氧化法为主要发展趋势。但该法要求高纯(>97%)乙烯、丙烯,并需大量特种合金和自控仪表及机电设备,这是中小型企业所难以办到的。此外,分离操作占整个裂解、分离总投资的80%,占总生产费的70%左右。 Acetaldehyde and acetone are one of the 18 important basic organic chemical products, and their production methods are more. At present, pure ethylene and propylene palladium are the main trends of development. However, the law requires that high-purity (> 97%) ethylene and propylene, as well as large quantities of special alloys and self-contained gauges and mechanical and electrical equipment, are hard for small and medium-sized enterprises to do. In addition, the separation operation accounted for the entire cracking, separation of 80% of the total investment, accounting for about 70% of the total production costs.
