use | alkaline orange is used for dyeing acrylic fiber and direct printing of fabric, and is also used for dyeing silk, wool and cotton fiber, with poor dyeing fastness. Basic orange 2 is mainly used for paint, plastic, ink, synthetic resin, ceramic body coloring, flat coloring, can also be used for cotton, acrylic, leather, paper, feather, leather, wood, bamboo and other products and silk dyeing. Used as acid-base indicator in biochemistry graduate students alkaline light yellow and alkaline orange 2 are used as pigments in food production and processing to make food bright in color and stable in color. They are used in chili powder, bean products, aquatic products and cooked meat products and other foods. |
production method | diazotize aniline, then couple with m-phenylenediamine, and then dissolve, crystallize, and dry to obtain the finished product. Raw material consumption (kg/t) m-phenylenediamine (100%) 440 aniline 365 sodium nitrite 280 hydrochloric acid (31%) 1320 aniline and m-phenylenediamine are used as main raw materials, aniline is first diazotized, then coupled with m-phenylenediamine, and the finished product is obtained through crystallization, filtration and drying. add 200L of water, 317kg of hydrochloric acid (31%) and 70kg of aniline to a diazo pot, stir and cool to 0-5 ℃, add 20%-30% sodium nitrite solution within 45min, continue the reaction for 20-30min after adding, and determine the reaction end point with potassium iodide starch test paper. add 250L of water and 88.25kg of m-phenylenediamine into the coupling pot, stir, raise the temperature to 65 ℃ until the m-phenylenediamine is completely dissolved, then lower the temperature to -4 ℃, and adjust the pH value to 6-7 with hydrochloric acid. Start to slowly add the diazonium solution cooled to -4 ℃, maintain the reaction temperature not more than -2 ℃, and continue the reaction until the diazonium salt disappears. Then add half the amount of water, raise the temperature to 95 ℃, add 5kg hydrochloric acid, stir evenly, let stand, crystallize, filter, dry at 60 ℃ to obtain about 200kg of product. |
