摘要：PROBLEM TO BE SOLVED: To provide a carbonylation method for an ethylene- or acetylene-based hydrocarbon which is capable of suppressing metallization of a metal complex occurring during the carbonylation in the presence of a catalytic system containing a group VIII metal complex. SOLUTION: This carbonylation method for an ethylene- or acetylene-based hydrocarbon includes a process to react, in the presence of a catalytic system containing (1) a supply source of a group VIII metal atom or its ion, (2) an organophosphine compound and (3) an acid, (a) an ethylene- or acetylene-based hydrocarbon compound having one or more unsaturated bonds between carbons, with (b) carbon monoxide and (c) at least one nucleophilic compound selected from the group consisting of water, alcohols and carboxylic acids, wherein the reaction process is advanced by maintaining the concentration of the carbon monoxide in the reaction liquor to be 0.05-0.3 mol/L.
