  A process for producing polyphenylene oxide which comprises contacting a phenolic monomer with oxygen in the presence of a catalyst composed of a manganese (II) salt and an ortho-hydroxyazo compound represented by the following formula: where A and B represent identical or different arylene ring having a valency of at least 2 and having an oxy group and an azo group directly linked to the ortho carbon atoms of the arylene ring and R represents hydrogen or lower alkyl group, or in the presence of said catalyst and an amine, in a polymerization solvent containing a base and thereby subjecting said phenolic monomer to an oxidative polymerization.

  一种生产聚苯醚的工艺，它包括在由锰（II）盐和下式代表的邻羟基偶氮化合物组成的催化剂存在下，使酚类单体与氧气接触： 式中 A 和 B 代表相同或不同的芳烯环，其价数至少为 2，并有一个氧基和一个偶氮基直接连接到芳烯环的正碳原子上，R 代表氢或低级烷基，或在所述催化剂和胺的存在下，在含有碱的聚合溶剂中，使所述酚类单体进行氧化聚合。

  An aqueous solution is formed by dissolving a dye made of alizarin and a humectant made of glycerin, and alkalized by dissolving a base (alkaline substance), thereby preparing a detector solution ( 101 ) in which the content of the humectant is about 20 wt %. An impregnated carrier ( 104 ) impregnated with the detector solution ( 101 ) is formed by dipping for 30 sec a sheet-like carrier ( 103 ) made of cellulose filter paper in the detector solution ( 101 ) so that the carrier ( 103 ) is impregnated with the detector solution ( 101 ). The impregnated carrier ( 104 ) is pulled up from the detector solution ( 101 ), and dried in dry nitrogen by evaporating a solvent such as water contained in the impregnated carrier ( 104 ), thereby forming an ozone detecting device ( 105 ).
