77743-24-9 - Introduction
Formazone Base (Formazone Base) is an organic compound with the chemical formula C9H10N4O2. It is a pale yellow crystalline powder, odorless. Formazone Base has good solubility in acidic conditions and low solubility in water. It has a strong alkaline.
Formazone Base is mainly used for the synthesis of organic dyes, especially photosensitive dyes. It has a wide range of applications in the fields of paper, fabric and image transmission. Formazone Base is also useful as a dye intermediate, sulfur dye, and light durability agent. It is capable of producing dyes of different colors by reacting with other compounds.
The method for preparing Formazone Base is usually obtained by reacting p-phenylenediamine with formamide. First, under the catalysis of sulfuric acid, p-phenylenediamine and formamide are condensed at a certain temperature to form the intermediate N-phenylformanilide. Then, the intermediate undergoes further reaction and treatment under basic conditions, and finally the Formazone Base is obtained.
When using Formazone Base, you need to pay attention to its safety. It is a combustible material and needs to be kept away from fire and heat sources. It is recommended to wear appropriate protective equipment such as goggles, long-sleeved clothing and gloves when handling and handling. Avoid inhalation of dust and contact with skin. If contact with skin or eyes occurs, rinse immediately with water. When stored, it should be stored separately from the oxidizing agent and strong acid.
