Abstract
Official abstract text for this publication.
To provide a production method for suppressing the reduction in production rate of a carbonyl compound due to transferring a noble metal component into liquid phase. A method for producing a carbonyl compound, including: a reaction step of reacting a carbonylation raw material with CO in liquid phase including a solid catalyst having noble metal complex on a resin carrier containing quaternized nitrogen to produce a carbonyl compound; a distillation step of distilling a reaction product liquid to recover gas phase distillate including the carbonyl compound; and a circulation step of circulating a bottom product from the distillation to reaction step. After part of the bottom product contacts with an acidic cation-exchange resin to remove nitrogen compound, liquid having higher moisture concentration than the bottom product contacts with the resin to extract noble metal complex captured by oligomer adsorbing the resin, and the complex is returned to the reaction step.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a carbonyl compound, comprising: a reaction step of reacting a carbonylation raw material with carbon monoxide in a liquid phase including a solid catalyst having a noble metal complex supported on a resin carrier containing quaternized nitrogen to produce a carbonyl compound; a distillation step of distilling a reaction product liquid from the reaction step to recover a gas phase distillate including the carbonyl compound; and…
