Q:What are the color reactions of Solvent Red 31 in different conditions?

Color reactions include: *In concentrated sulfuric acid: Turns purple; upon dilution, turns pink *With concentrated hydrochloric acid: Turns red *With concentrated sodium hydroxide solution: Turns brown

Q:What is the heat resistance of Solvent Red 31?

Solvent Red 31 exhibits a markedly lower thermal tolerance than the widely used Solvent Red 24. Under static heat exposure, Solvent Red 31 maintains integrity for 1 hour at 120 degree, whereas Solvent Red 24 demonstrates stability up to 300 degree under analogous testing conditions.

Q:What is the production method of Solvent Red 31?

The production involves diazotization of 4-(phenyldiazenyl)benzenamine (para-aminoazobenzene), followed by coupling with 7-hydroxynaphthalene-1,3,6-trisulfonic acid, and finally conversion to the dicyclohexylamine salt.
