Red GN - Introduction
Acid red 122 is an organic synthetic dye, also known as red AZO dye. Its chemical name is 2-hydroxy-3-amino-5-(N-ethyl-N-(p-toluenesulfonamido)) benzenesulfonic acid.
Acid red 122 has good solubility and color stability. It usually shows a bright red color and is highly stable to light, heat and chemicals.
Acid Red 122 is mainly used in dyeing and printing and dyeing processes in the textile industry. It can be used to dye textiles and paper, giving them a bright red color. In addition, acid red 122 is also used in traditional printing and pigment manufacturing.
A common method for preparing acid red 122 is through an azo coupling reaction. The reaction is a coupling reaction of an amine compound and an aromatic amine to obtain a dye by azotization of an azo intermediate.
Acid red 122 is a toxic substance. Chemical safety practices must be strictly observed during use or preparation. Contact with skin and eyes should be avoided, and if there is contact, rinse immediately with water. At the same time, it should be operated in a well-ventilated area to avoid inhaling its dust or steam.
