PURPOSE:To readily and efficiently obtain the present compound in high selectivity at a low temperature under a low pressure, by reacting vinyl chloride with CO and H2 in the presence of a catalyst, such as a rhodium compound and trivalent organic phosphorus compound, coexisting with an organic acid and base as a cocatalyst. CONSTITUTION:Vinyl chloride is reacted with CO and H2 in the presence of a catalyst of a rhodium compound, such as hexadecanylhexarhodium, and a trivalent organic phosphorus compound, such as triphenylphosphine, or an oxide thereof coexisting with an organic acid, such as phthalic acid, and a base, such as NaOH, further in the presence of preferably water, preferably in a solvent, such as toluene, at 10-150 deg.C under 10-300kg/cm<2>G pressure to afford the aimed compound useful as an intermediate for cosmetics and agricultural chemicals, etc. Furthermore, high activity can be stably maintained for a long period without accumulating by-products in a reactor and loss of rhodium can be reduced without requiring frequent regeneration of the catalyst, etc. |
