<P>PROBLEM TO BE SOLVED: To provide a method for producing a hydroxy compound, which method is one for producing the hydroxy compound by the hydrolysis of a chlorinated hydrocarbon compound and has an excellent feature that hydrochloric acid recovered from the formed hydrogen chloride and unreacted water can be efficiently utilized, and hydrogen chloride can be recovered from the hydrochloric acid in a manner efficient from the viewpoint of energy saving. <P>SOLUTION: The method for producing the hydroxy compound comprises the hydrolysis step of bringing a chlorinated hydrocarbon into contact with hydrochloric acid to obtain a mixture containing a hydroxy compound and hydrogen chloride, the hydrochloric acid separation step of separating the mixture from the hydrolysis step into a portion based on hydrochloric acid and a portion based on a chlorinated hydrocarbon compound and a hydroxy compound, and the hydrogen chloride separation step of separating and recovering the portion based on hydrochloric acid from the portion obtained from the hydrochloric acid separation step and recirculating the remainder into the hydrolysis step. <P>COPYRIGHT: (C)2007,JPO&INPIT |
