METHOD OF MANUFACTURING ACETIC ACID

摘要

ACETIC ACID IS MANUFACTURED BY CARBONYLATING METHANOL WITH CARBON MONOXIDE BY WAY OF A HETEROGENEOUS CATALYTIC REACTION IN A BUBBLE COLUMN REACTOR (1, 11, 21). THE CARBONYLATING REACTION IS CONDUCTED WITH A SOLID CATALYST CONCENTRATION OF NOT LESS THAN 100 KG/M3 IN TERMS OF THE REACTION VOLUME. FOR THE REACTION, THE PARTIAL PRESSURE OF CARBON MONOXIDE IN THE REACTOR IS CONFINED TO A RANGE BETWEEN 1.0 AND 2.5 MPA WHILE THE EXHAUSTION RATIO OF CARBON MONOXIDE IS CONFINED TO A RANGE BETWEEN 3 AND 15% OF THE THEORETICAL REACTION VOLUME OF CARBON MONOXIDE AND THE LIQUID SUPERFICIAL VELOCITY IS MADE TO BE FOUND IN A RANGE BETWEEN 0.2 AND 1.0 M/SEC.
