METHOD FOR PRODUCTION OF ACETIC ACID BY OXIDATION OF ETHYLENE AND SOLID METAL COMPLEX CATALYST FOR ITS REALIZATION Russian patent published in 1995 - IPC

FIELD: organic chemistry. SUBSTANCE: method involves oxidation of ethylene with the help of oxygen, the process is carried out in gaseous phase in the presence of water and heterogeneous metal complex catalyst, molar ratio of ethylene, oxygen and water being 1:(1.5-2):(3-6). The process takes place at elevated temperature and at increased pressure. Quantity of elements which contains said solid catalyst are calculated according to given formula where M is chosen of group which contains cadmium, alkali and alkali-earth metals, a is 0.0005-0.2, b is 0-3a, c is 0.5-2.5, x is determined as summary valence of other elements comprising said catalyst. Said catalyst also contains crystalline TiP₂O₇ being prepared during calcination catalyst. EFFECT: improves efficiency of the method. 15 cl, 1 tbl
