<P>PROBLEM TO BE SOLVED: To provide a method for producing a hydroxy compound by hydrolyzing a chlorohydrocarbon compound in the presence of a catalyst containing nickel supported on a metallosilicate, and exhibiting excellent characteristics to prevent the lowering of the catalytic performance at the start of the production process and develop high catalytic activity in stationary operation. <P>SOLUTION: The reaction is started at ≤405°C and then the temperature is elevated. The starting temperature of reaction is defined by the temperature to start the coexistence of the chlorohydrocarbon and steam on the catalyst, and the temperature is ≤405°C, preferably 300-400°C. Too high reaction temperature results in the lowering of the catalytic performance in the case of making only the chlorohydrocarbon into contact with the catalyst in the absence of steam at the start of the reaction, and too low temperature fails in sufficient development of the catalytic performance and sometimes causes the lowering of the conversion of the chlorohydrocarbon. <P>COPYRIGHT: (C)2009,JPO&INPIT |
