Abstract: The aims of doctor 'work was synthesis of dyes used as starting material 1-amino-4-brom-9,10-anthraquinone-2-sulphonic acid (bromamine acid) taking into two tinctorial clases.The paper presents synthesis of amino-compound with reactive group β-sulphato-ethyl-sulphonil-aniline and β-sulphato-propionyl-amide-N-substitute.The β-sulphato-ethyl-sulphonil-aniline was use for synthesis a REMAZOL reactive antraquinonic dyes.In the synthesis of β-sulphato-ethyl-sulphonyl-aniline was been replace the ethylen-oxid wih 2-clor-ethanol for reacts with N-acetyl-benzen-2-sulphinic acid. The reactive vinyl-suphonic dyes was been prepared by β-sulphato-ethyl-sulphonil-aniline and bromamine acid in the presence of de K2CO3 and copper chloride ,new proceses. The β-sulphate-ethyl-sulphonil-aniline, diazoted and condensed with 1,4'phenil- methyl-pyrazolone formed azoic reactive dye. In synthesis of β-sulphato-propionyl-amide-N-substitute the acrylic chloride was remplace with β-chloro-propyonic chloride . The reactive PRIMAZIN dyes was obtined by condensation of bromaminic acid and this β-sulphato-propionyl-amide-N-substitute. New bi-reactive dyes PROCINIL was synthetized : 1N(γ-chloro-β-hydroxi-propyl)2-methoxi-4-N[N(γ- chloro-β-hydroxi-propyl)-p-phenylen-diamino]9,10-antraquinone şi 1-N(γ-chloro-β-hydroxi-propyl)-4-N[N(γ-chloro-β-hydroxi-propyl)-p-phenylen-diamino]9,10-antraquinone. Reactive POCINIL dyes was synthetised by bromamine acid and 2-amino-benzoic acid and derivates (2-amino- 5.iod-benzoic acid, 2-amino- 3,5, dibrom-benzoic acid, 2-amino-4-chloro-benzoic acid, 2-amino-5-chloro-benzoic acid, 2-amino-5 nitro-benzoic acid, 2-amino-5-sulpho-phenil-benzoic acid)and then alchylate the amino group with 1-chloro-2,3-epoxy-propan.it was find the optim conditions for condensation of 2-amino-benzoic acid with bromaminic acid and was used for 2-amino-benzoic' s derivates.The acid dyes was been used as starting materials for reactive dyes by two way:reacts with 1-amino-2,3- epoxy-propan and ciclyed, the compoud obtained, by added of chlorosulphonic acid when result disperse reactive dyes.The two experimental proceses was new.The 2 way was described for 2 dye's clase. Another way of experimenthal works was preparation of 9,10-antraquinonic disperse dyes by condensation of bromamine acid and amino- carbazol. For this the 1-amino-4-N-(3-carbazolyl)-9,10-antrachinon-2-sulphonic acid was refluxed in alcaline solution with glucose in order to eliminate the sulphonic group and was refluxed with methilic alchool /butilic alchool for replace the sulphonic group with OCH3 and OC4H9 and the formed compound was alchylate with dimethil-sulphate . The 9,10-anthraquinonic disperse dyes was prepared by condensation of 1-amino-4-phenyl-9,10-antraquinone-2-sulphonic acid with aniline.The starting materials was refluxed in alcaline solution with glucose in order to eliminate the sulphonic group and was methilation with methilic alchool.The triazinic,antraquinonic dyes was prepared by two way:react first by triazin-2-yl chloride and then with methanol /phenol ,follows by added of 2,6 dimehoxi chloride /2,6,diphenoxi chloride
