Preparation of Dye
(A) Auramine-o:- (A) Auramine-o:- It is prepared bye heating Michlers ketone with Amonium chloride and Zinc and 0c
Zinc chloride at 150-160 the Auramine base so obtained on treatment with HCL is converted into Auramine-o, the Michlers ketone required re quired for this syntesis is prepared by condensing N-Dimethyl anilne with Phasgene.
(B) P rimuline:- It is prepared by heating P-toluidine and sulphur in appropriate propprtions at oc
200-280 respectively, Primuline base is formed then the sulphonating of Primuline base gives Primuline.
(C) M ethylene Blue :It is obtained by oxidising P-dimethyl-aniline, with acid dichromate in pres ence of sodium thiosulphate, followed by condensing the resulteing 4-(dimethyl amino) aniline 2-thio sulphonic acid with dimithyl aniline to form an indamine, and oxidising by dichromate and copper sulphate to yield methylene blue.
(D) Alizarine:- It is obtaned by heating under pressure silver salt in the presence of custic soda oc
and Pot. Chlorate at about 180 , The resulting Product is di-sodium alizarate which on acidifide cation give Alizarine Dye.
