C.I. Solvent Yellow 1 - Uses and synthesis methods
use
1. dye intermediates. Used to synthesize azo dyes, disperse dyes, oxazine dyes; also used to make paints and pigments, as well as alcohol-soluble yellow and pH indicators.
2. Used to produce azo dyes and oxazine dyes, etc., and used as alcohol-soluble yellow and pH indicator
3, acid-base indicator and nitrite test. Organic synthesis.
production method
Starting from aniline, it is obtained by condensation with aniline after diazotization and translocation rearrangement. Put aniline and sodium nitrite solution into the reaction pot, stir at 30-40 ℃, add 30% hydrochloric acid within 2.5-3h, and then raise the temperature to 50-55 ℃ for indexing.
