What is the melting point of phenyl-azo beta-naphthol?
The melting point of phenylazo- beta-naphthol is somewhere from 131 to 133 degrees Celsius. Phenylazo- beta-naphthol is also called as Sudan I.
In diazotization beta naphthol used?
Actually beta naphthol is not used in diazotization.It is used to confirm the formation of diazonium salt.Because the diazonium salt so formed undergo the COUPLING REACTION with beta naphthol to form a ORANGE DYE or DYESTUFF. eg. aniline with HCl and Sodium Nitrite followed by the treatment with beta naphthol in NaOH at 0-5 degree celcius forms Phenyl azo-beta naphthol(orange).
What happens when benzene diazonium chloride is treated with alkaline 2-naphthol?
it results in the formation of phenyl-azo-2-naphthol, an azo dye which is orange-red in colour
What would be the IUPAC name for azo dye using p-chloroaniline instead of sulfanilic acid?
4-[(2-hydroxy-1-naphthalenyl)azo]phenyl chloride monosodium salt

What is the reaction of b-naphthol with sodium hydroxide?
It creates a brownish liquid that makes an azo dye called Para Red when it is combined with a bright yellow mixture created from para-nitroaniline/HCl/sodium nitrite. So the reaction that you are talking about basically makes a brownish dye.

What azo dye is formed when salicylic acid reacts with amino benzoinc acid?
3,4'-dicarboxy-4-hydroxy azo benzene.it is a coupling reaction...........it forms a azo dye.when salicylic acid reacts with amino benzoinc acid.. initially amino benzoinc acidreacts with nitrous acid and hydrochloric acid to form azo group....azo group: -N=N-then that azo compound react with salicylic acid to form an azo dye(3,4'-dicarboxy-4-hydroxy azo benzene).C6H4COOH(OH)-salicylic acidCH2NC6H4CO2H- amino benzoinc acid.H2NC6H4CO2H+HNO2+HCL-->CL-N=N-C6H4COOH(AZO COMPOUND)3,4'-dicarboxy-4-hydroxy azo benzene.(AZO DYE)
