Nishida, K.; Ohtsu, T.; Tanaka, S.; Miyatake, M.; Hotsuta, T.; Iwamoto, H. published an article in 1973, the title of the article was Preparation of 2-nitro-N,N-dimethylaniline-4-sulfon-N-alkylamides and their dyeing properties on synthetic polymer fibers.Recommanded Product: 97-09-6 And the article contains the following content:
Disperse dyes (I, R = H, Me, Et, Pr, Bu, pentyl) were prepared and the substantivity of I on polyamide, cellulose acetate, acrylic, and polyester fibers increased with increasing chain length of R. In general, bright yellow dyeings were obtained, the brightest on cellulose acetate, with good fastness properties except for poor light-fastness. The amount of dye transferred in heat-transfer printing decreased as the chain length of R increased. Thus, 4,3-Cl(O2N)C6H3SO2Cl was treated with RNH2, the intermediate 4,3-Cl(O2N)C6H3SO2NHR treated with NMe2 to give I. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Recommanded Product: 97-09-6
