| introduction | dispersible yellow 3 is a very important chemical raw material. it can be synthesized or obtained from coal tar, but both have to go through a series of separation and purification processes. Therefore, in addition to the raw materials can not be fully utilized, but also bring additional pressure to environmental protection. In the field of dye chemical industry, dyes have been prepared along with single phenols and their derivatives, especially disperse yellow 3. |
| Preparation | After diazotization of paracetamidine, it can be coupled with phenol and its derivatives to obtain a series of yellow dyes. When it is coupled with p-methylphenol, it is C.I. Disperse Yellow 3. |
| use | dyeing polyester and its blended fabrics |
