PROSES PEMBUATAN ALDEHIDA TERMINAL

摘要

A hydroformylation process for preparating a terminal aldehyde involves reacting an ethylenically unsaturated organic compound with carbon monoxide and hydrogen in the presence of a catalyst system iridium or rhodium and a bidentate organic phosphite ligand wherein the two phosphorus atoms of the phopshite ligand are linked with a 2,2'-dihydroxyl-1,1'-binapthalene bridging group having the following structure (Q): in which R1 and R2 are substituents other than hydrogen and in which R3 and R4 are the same or different substituted monovalent aryl groups and/or any one of OR3 and OR4 connected to one phosphorus atom forms an -O-R5-O-group, where R5 is a divalent organic group containing one or two aryl groups.
