Procedure

Then, 0.620 kg of PhOH was charged into reaction vessel 50 and stirred at 180° C. (as measured at the jacket) under atmospheric pressure, to thereby effect a reaction. During the reaction, unreacted PhOH was distilled off from the top of distillation column 54 disposed on reaction vessel 50 at a rate of 0.1 kg/hr through conduit 55A. Thus, in reaction vessel 50, in the same manner as in Example 2, a reaction proceeded in which lead(II) carbonate reacts with PhOH to form diphenoxy lead, carbon dioxide and water. The carbon dioxide and water formed in the above reaction were withdrawn from the reaction vessel together with the unreacted PhOH distilled off. A reaction mixture, which remained in reaction vessel 50 after performing the above reaction for 2 hours, was withdrawn from reaction vessel 50 and transferred through conduit 46 and introduced into storage vessel 47.
