This paper reported the synthetic process of an acetyl ketene derivative, 1-(4 '- sulpho phenyl)-3- methyl- 5- pyrazolone. The coupling reaction of 1-(4 '- sulpho phenyl)- 3- methyl- 5- pyrazolone with the diazo compounds of some anilines and substituted anilines was thoroughly introduced. The synthesis process was used to prepare many varieties of acidic dyes, reactive dyes and mordant dyes. These varieties of dyes can be used in wool, silk, nylon, viscose, cotton and other fibers and fabrics, respectively, as well as in textile printing and dyeing industry. This paper also listed the trade names, chemical structures, CAS numbers and EC registration numbers of these products. Besides, the synthetic process diagrams, applications, and main domestic production enterprises were stated in this paper.
