3,7-Bis(dialkylamino)phenoxazin-5-ium salts having different amino groups (dimethylamino, diethylamino, dipropylamino, dibutylamino, and pyrrolidyl) and counter anions (chloride, bromide, iodide, hydrogensulfate, and nitrate) were synthesized in up to 80% isolated yield as blue cationic dyes. In addition, 3,7-bis(diethylamino)phenothiazin-5-ium and 3,7-bis(diethylamino)phenoselenazin-5-ium iodides were also synthesized in 20% and 17% isolated yields, respectively. Polypropylene fabrics were dyed with the above synthesized blue cationic dyes. As an evaluation result, it has been found that the moderate size such as diethylamino groups at the 3 and 7 positions of phenoxazinium salts is suitable for the dyeing ability.

各种3,7-双（二烷基氨基）苯恶嗪5盐盐和硫和硒类似物的聚丙烯织物的合成和蓝染能力

合成了具有不同氨基（二甲氨基，二乙氨基，二丙氨基，二丁氨基和吡咯烷基）和抗衡阴离子（氯离子，溴离子，碘离子，硫酸氢根和硝酸根）的3,7-双（二烷基氨基）苯恶嗪-5-盐作为蓝色阳离子染料，分离出的产率为80％。另外，还分别以20％和17％的分离产率合成了3,7-双（二乙基氨基）吩噻嗪-5-鎓和3,7-双（二乙基氨基）吩硒氮嗪-5-碘化物。聚丙烯织物用上述合成的蓝色阳离子染料染色。作为评价结果，发现中等大小的苯恶嗪鎓盐的3和7位的二乙氨基基团适合于染色能力。
