    摘要: IN THE LIQUID PHASE OXIDATION OF BUTANE THE TOTAL PRODUCTIVITY AS WELL AS THE PRODUCTIVITY OF METHYL ETHYL KETONE CAN BE IMPROVED BY TREATMENT OF RECYCLE BUTANE IN ORDER TO REDUCE THE CONCENTRATION OF CARBON OXIDES, WATTER AND METHYL EHTYL KETONE DISSOLVED THEREIN. SIMILAR IMPROVEMENTS CAN BE ACHIEVED BY RECYCLING BUTANE TO THE TOP RATHER THAN TO THE BOTTOM OF THE REACTION ZONE.

    摘要: A BYPRODUCT CARBONYL STREAM PRODUCED IN THE PREPARATION OF BUTADIENE BY THE CATALYTIC DEHYDROGENATION OF BUTYLENE, WHICH CONTAINS WATER, ACETONE, METHYL VINYL KETONE AND METHYL ETHYL KETONE, IS UPGRADED BY A NOVEL PROCESS WHEREIN THE WATER CONTENT IS SEPARATED AS A HEAVY PHASE BY CALCIUM CHLORIDE TREATMENT, THE ACETONE IS REMOVED BY DISTILLATION, THE METHYL VINYL KETONE IS REACTED WITH AN ETHYLENICALLY UNSATURATED COMPOUND, AND THEREAFTER THE METHYL ETHYL KETONE IS SEPARATED FROM THE REACTION MIXTURE.
