Abstract: PURPOSE:To obtain the titled compound, by using a trivalent organic phosphorus compound or oxide thereof and a water-soluble amine having a specific range of a pKa as a base in reacting vinyl chloride with CO and hydrogen in the presence of an Rh compound, the base and water. CONSTITUTION:Vinyl chloride is reacted with CO and H2 in the presence of an Rh compound (e.g. rhodium oxide or hexadecacarbonyl hexarhodium), base and water to provide the titled substance. In the process, a trivalent organic phosphorus compound (e.g. trimethylphosphine or triethylphosphite) or oxide thereof (e.g. triethylphosphine oxide) and a water-soluble amine having a pKa of >10-

Abstract: PURPOSE:To improve the production efficiency of the titled compound useful as a synthetic intermediate for agricultural chemicals, pharmaceuticals, etc., by reacting vinyl chloride with carbon monoxide and H in the presence of a rhodium compound and a base consisting of a combination of a trivalent organic phosphorus compound, etc., with a specific compound having high boiling point. CONSTITUTION:The objective compound is produced by reacting vinyl chloride with carbon monoxide and hydrogen at 20-80 deg.C in the presence of a rhodium compound and a base consisting of a combination of (A) at least one kind of a trivalent organic phosphorus compound (e.g. trimethylphosphine or trimethyl phosphite) or oxide of a trivalent organic phosphorus compound (e.g. triethylphosphine oxide or triphenylphosphine oxide) and (B) at least one kind of an amino alcohol having a boiling point of >=180 deg.C under 1atm. (e.g. diethanolamine) and preferably in the presence of water. The rhodium compound is preferably a halogen-free compound.
