Method of preparing active azodye
专利摘要:
Azo dye of the formula <IMAGE> (1) wherein X represents an alpha , beta -dichloropropionyl or alpha , beta -dibromopropionyl group or an alpha -chloroacryloyl or alpha -bromoacryloyl group, Y represents hydrogen, chlorine, low molecular alkyl or alkoxy or a sulpho group, Z represents an OH group or a radical of the m-sulphobenzene series, R represents a substituted or unsubstituted alkyl radical of 1 to 8 carbon atoms, and m is 1 or 2, and wherein the group -NH-X is in meta- or para-position to the azo group. These dyes give strong, brilliant, and bright yellow dyeings on cotton, regenerated cellulose, and natural or synthetic polyamide materials, characterized by excellent light fastness and good wet fastness. 公开号:SU871736A3 申请号:SU762383051 申请日:1976-07-19 公开日:1981-10-07 发明作者:Де Монтмоллин Рене;Мойзецаль Дитер 申请人:Циба-Гейги Аг (Фирма); IPC主号:

Z, Y, m have the indicated meanings, combined with the aero composition of the general formula SNS .. CIONH2 I r where R has the indicated meanings. Example 1. 11.6 g (0.02 mol) of 1-amkno-2-sulfo-5-a 0-dnbromopropionylaminobenzene (wet) is suspended in 100 ml of water at room temperature. 3 g of potassium bromide was added to the suspension, then the mixture was acidified with 5 ml of 10N. hydrochloric acid and 40 ml of 1N are added dropwise. sodium nitrite solution. Upon termination of the diazotized insignificant excess of nitrite is decomposed by sulfamic acid. 5.75 g (0.02 mol) of 1-ethyl-4-methyl-6-hydroxy-2-pi. Ms-don-3-carbonamide (wet) is dissolved in 100 ml of water with 4 ml of Yun. caustic soda solution when heated and cooled to room temperature. The solution of the color-forming component is slowly poured into the suspension of the above diazo component with stirring. The resulting solution is acidified with 2N. caustic soda solution to pH 6, the dye is precipitated by the addition of sodium chloride, filtered and dried in vacuum at 50 C. The dye dyes nylon or wool in the cleaning, gives greenish-yellow shades of high light fastness. Light resistant stains on the material are obtained if, in the above example, instead of 1-amnno-2-sulfo-5-a, ft-dibromopropyl-aminobenzene, an equivalent amount of 1-amino-2-sulfo-5-0, (dichloroproshonyl-aminobenzene or 1-amino- 2,6-disulfo-4-a, / 3-dibromopropane: nilaminobenzene. one Other yellow dyes with similar properties are obtained when ordered below, in column 1, the diazo components are brought into contact with the two color-forming components (azocomponents) indicated in column 2. .

At the end of the dosing, pour 5.8 g (0.02 mol) of the humid 1-ETSH1-4-methyl-6-hydroxy-2-pyridone-3-carbonamide and adjust the pH to 4-5 with the addition of 5.5 g of NaHCOs. The reaction mixture is then adjusted to pH 12 with sodium hydroxide solution at 10 ° E to remove hydrogen bromide, kept at pH 12 for 30 minutes, and then adjusted to pH 7 with hydrochloric acid.

The suspension is mixed with 3 ml (0.03 mol) of a Yun hydrochloric acid solution and diazotized at room temperature. The diazotization is completely finished in 30 minutes. 29.1 ml are slowly added to the acidic diazosuspension ( 0.01 mol) alkaline solution of 1-ethylhexyl-4-methyl-6-hydroxy-2-pyridine-3-carboxamide.
