METHOD OF CARBONYLATION PRODUCT PRODUCING Russian patent published in 1999 - IPC

Abstract RU 2133731 C1

FIELD: chemical technology. SUBSTANCE: carbonylated product from the liquid reaction mixture of carbonylation process is extracted by evaporation being optional heat supply that results to formation of a vapor fraction containing the carbonylation product and a liquid fraction containing iridium catalyst. Water concentration in the separated liquid fraction is maintained at the level at least 0.5 wt.-%. Catalyst used for carbonylation reaction has lesser tendency for decrease of stability and/or solubility. EFFECT: improved method of producing. 24 cl, 3 dwg, 5 tbl, 5 ex
