EINECS 203-021-5 - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Uses | Mainly used as an intermediate for reactive dyes and disperse dyes Dye intermediates. Mainly used for preparing reactive yellow K-RN and disperse dyes. |
| Production method | is obtained by acylation of m-phenylenediamine. Add water and m-phenylenediamine to the reaction pot to dissolve. Add 30% hydrochloric acid, stir for half an hour, then add acetic acid, control the reaction temperature at 40 ℃, keep warm and stir for 1h, add refined salt for salting out, and filter. After neutralization, m-aminoacetanilide is obtained. Acylation operations may also use acetic anhydride as a raw material. Raw material consumption quota m-phenylenediamine 1021kg/t, acetic anhydride 1013kg/t, hydrochloric acid 475kg/t. |
