Introduction | acid orange 63 is orange powder, which is suitable for dyeing wool, silk, nylon and wool blends, it can also be used for direct printing of wool, silk and nylon fabrics. Generally used alone, can also be color matching, for dyeing wool wool and loose hair. The levelness was good, and the dyeing rate was low. |
Use | weak acid orange PR is suitable for dyeing wool, silk, nylon and wool blends, and can also be used for wool, silk, direct printing of nylon fabric. Generally used alone, can also be color matching, for dyeing wool wool and loose hair. The levelness was good, and the dyeing rate was low. Used for wool and other fibers in the same bath dyeing, nylon color and wool similar, silk shallow, acetate fiber and cellulose fiber slightly stained. |
production method | with 3-sulfonic acid benzidine, 1-(p-sulfonic acid phenyl)-3-methyl -5-pyrazolone, phenol and p-Toluenesulfonyl chloride as raw materials, first 3-sulfonic acid benzidine double nitriding, then with 1-(p-sulfonic phenyl) 3-methyl-5-pyrazolone is first coupled, followed by a second coupling with phenol and finally by condensation with P-Toluenesulfonyl chloride to give the product. After salting out, filtration, drying, grinding to get the finished product.. |
