then it make an azo Component or azo dye. In this coupling reaction, aniline is directly reacted with benzene diazonium chloride and with maintain pH – > 7. In this reaction, beta nephthol (napthelene+alcohol = beta nephthol) is react with benzene diazonium chloride then it make azo component. Aniline is an aromatic amine and after reaction with aniline it gives yellowish azo dye.ģ. azo dye test is carried out for produced aroma tic amines (aniline). this product is called yellow azo color or yellow azo dyes. Aniline solution is react with same benzene diazonium chloride then it is given yellow product. When benzene diazonium chloride react with phenol then it make azo component, it is orange product, this is called orange azo dyes.Ģ.

Take Aromatic Amines (aniline), it react with the presence of Nano2/HCl at 0-5☌.ĭiazonium component (benzene diazonium chloride)Ĭuppling reaction with cuppling component process with phenol or nepthole basic dye are used for windly colouration of acrylic, acrylic/cotton materials.Īzo dye preparation flow chart/ process sequence but if we are talking about other dye, azo dye are more complex and difficult to dyeing processing but it is easy to done with the basic dye or acid dye. This way, preparation of an azo dye will be completed. (reaction with coupling components process with phenol and naphthol). In this process, first of all aromatic amines (aniline) taken then after reaction, it is transferred to diazonium component.Īfter this, azo coupling reaction is carried out with phenol and naphthol. Now, we will also discuss about preparation of an azo dye with the help of flow chart/process sequence. and then, coupling reaction is carried out with phenol then result (coloring compound )azo dyes is formed as a product. preparation of azo dye from anilineĪfter this reaction, as a results, it is given benzene Diazonium chloride. Preparation of an azo dyes from aniline is, first aniline is react in the presence of NaNO2/HCl at temperature 0-5☌. Read also:- Disperse dye process, dyeing of polyester with disperse dye? In case of azo dye, the best interact with azo dye is 3 amino benzene sulfonic acid. This dye gives good effect on cellulosic materials as well as wool fibers. When dyeing with your azo dye which fibers seemed to interact best with the dye?Īnswer – Azo dyes are soluble in water therefore, azo dyes are easily dissolve in water.Īzo dyes are contain azo function group (N=N). it is made from phenol, aniline and amines. it is used for treatment of textile materials. This is also known as azo compound and this is also called an azo dyes. it contains function group such as (N=N). Read also:- What is Terry towels and Terry towels dyeing process? Azo dye structureĪzo dye is a one type of organic compound. so, some company are banned of some class of azo dyes. it may increase chances to damage of skin.Īlso increase the chances of exposure when wearing garments. this dyes are easily accumulated and easy to absorb in the body.

This dye are easily observed on the skin of body during dyeing process. when this dyes are contect on skin then it may increase chances of skin cancer.Īzo dyes could be banned from contact because azo dyes are highly soluble in water.

this is the reason it gives good colour (shade) on materials.īut some azo dyes is harmful for skin but not all. This dyes have some important colouring Function property. This dye gives good effect on cellulosic materials.

this are the important class of azo dyes which is windly used in textile industry. This dyes are produced strong colour with good depth of shade on to the materials.ĭifferent popular azo dyes are also be used in textile industries, for example Acid orange 7, (2- naphthol or orange-2).ĭirect blue 1 5, and m ethyl yellow, acid red 13. and Some important dyes are based on arylamines.Īzo dyes are windly used for the dyeing of cellulose materials as well as polyester materials. Its broken down with the help of high temperature. This dyes are contain azo function group (N=N).Īzo dye are properly bound to aromatic ring. first off all, we will discuss about azo dye.Ĭheck Also: – Coupling reaction and it’s examples? What is azo dye? azo dye testĪzo dyes are soluble in water. We will discuss about test for amines such as azo dye test, carbylamine test, hinsbarge test, solubility test, litmus test.īy the end of this article You can properly understand about test for amines. this dyes are mostly used for dyeing of textile cloths. it is bound to aromatic ring and it is easy to dissolve in water. Azo dyes are contain azo function group (N=N).
