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?
When benzene diazonium chloride is treated with alkaline 2-naphthol, a diazo-coupling reaction occurs. This results in the formation of an azo dye, specifically the orange-red compound called Sudan I. This reaction is commonly used for the synthesis of azo dyes in organic chemistry.
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 does mean for azo bond in textile?
An azo bond in textiles refers to a chemical bond between nitrogen atoms in azo dyes, which are commonly used in dyeing fabrics. This bond is responsible for the vibrant colors produced by azo dyes, but there have been concerns about the potential release of harmful substances during the dyeing process or if the fabric is exposed to certain conditions. Regulations exist to ensure azo dyes used in textiles are safe for consumers.

What are the Pharmacological uses of 4-nitrobenzene azo naphthol?
4-nitrobenzene azo naphthol is commonly used as a dye in histological staining procedures for identifying and visualizing specific structures under a microscope. Additionally, it has also been studied for its potential in developing selective and sensitive sensors for metal ions due to its complexation properties.

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 is the birth name of Anatoliy Azo?

What is an azo dye?
An azo dye is any of a number of yellow to red synthetic dyes which contain an azo or diimide functional group.
When was Assaf Azo born?
Assaf Azo was born on 1984-05-17.
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)
