| titleOfInvention | Production process of polyphenylene ether |
| abstract | A process for producing a polyphenylene ether by oxidative polymerization of a phenol compound using a catalyst and an oxygen-containing gas, wherein the catalyst comprises a copper compound, a bromine compound, a diamine compound represented by the following formula (1):(wherein, R1, R2, R3 and R4 each independently represents hydrogen or a C1-6 linear or branched alkyl group with the proviso that all of them do not represent hydrogen simultaneously, and R5 represents a linear or methyl-branched C2-5 alkylene group), a tertiary monoamine compound and a secondary monoamine compound, wherein the process comprises the steps of: controlling an absolute pressure at a gaseous phase of a reaction vessel to a range of from 0.098 MPa to less than 0.392 MPa; and feeding the oxygen-containing gas to the reaction vessel, the oxygen-containing gas having an oxygen partial pressure, in terms of an absolute pressure, of from 0.0147 MPa to 0.0883 MPa. |
