Desai, C. K.; Desai, K. R. published an article in High Performance Polymers. The title of the article was 《Azo dyes based on 2-naphthol-formaldehyde oligomer》.Safety of 2-Amino-2,4-dichlorodiphenyl ether The author mentioned the following in the article:
A series of new oligomeric disperse dyes were prepared by coupling various diazonium salts of aniline ethers to a 2-naphthol-formaldehyde oligomer. They were characterized in terms of their softening points, color, solubility, and IR and UV-visible spectral studies. The structural property relationships were discussed. Application to polyester and nylon resulted in yellow, orange, and pink-to-red shades having good to excellent light- and washfastness properties. In addition to this study using 2-Amino-2,4-dichlorodiphenyl ether, there are many other studies that have used 2-Amino-2,4-dichlorodiphenyl ether(cas: 56966-48-4Safety of 2-Amino-2,4-dichlorodiphenyl ether) was used in this study.
2-Amino-2,4-dichlorodiphenyl ether(cas: 56966-48-4) belongs to anime. Acylation is one of the most important reactions of primary and secondary amines; a hydrogen atom is replaced by an acyl group (a group derived from an acid, such as RCOOH or RSO3H, by removal of ―OH, such as RC(=O)―, RS(O)2―, and so on). Reagents may be acid chlorides (RCOC1, RSO2C1), anhydrides ((RCO)2O), or even esters (RCOOR′); the products are amides of the corresponding acids.Safety of 2-Amino-2,4-dichlorodiphenyl ether
