Method for producing polyphenylene ether |
abstract |
(57) [Problem] To provide an efficient method for producing polyphenylene ether with improved productivity. SOLUTION: When oxygen and a phenolic compound are reacted using a specific catalyst according to the present invention to produce polyphenylene ether, the absolute pressure of the gas phase in the reaction vessel is 0.09. 8 MPa or more and less than 0.392 MPa, and the oxygen partial pressure contained in the oxygen-containing gas to be ventilated is 0.04 in absolute pressure. By passing an oxygen-containing gas having a pressure of 147 MPa or more and 0.0883 MPa or less into the reactor. |
