Molecular Structure:
C.I.Sulphur Yellow 6,C.I.53105,CAS 1326-63-2
CAS Registry Number:1326-63-2
Manufacturing Methods : Will the 4-Methylbenzene-1,3-diamine and 4-(4-Aminophenyl)benzenamine mixture and sulphur in 220 ~ 230 ℃ calcination, then use Sodium hydroxide deal with the molten material, filtering, and hydrochloric acid or to the solution through the air on precipitation. Contains a larger percentage of 4-(4-Aminophenyl)benzenamine mixture at low temperatures when sulfide generating a yellow adjustable dye.
Properties and Applications: dark yellow to dark red light yellow. In the sodium sulfide solution solubility is good, for yellow orange; In concentrated sulfuric acid partly dissolved.
