Basic Information
Product Name:N,N-Dimethyl-p-phenylenediamine
CAS Number: 99-98-9
Chemical Formula: C8H12N2
Molecular Weight: 136.20
Appearance: It is a colorless to light red crystal or liquid, which is prone to oxidation and color change in the air.
Melting Point: 34 - 36ºC
Boiling Point: 262 - 264ºC
Density: 0.955 g/mL (at 20ºC)
Solubility: It is slightly soluble in water and readily soluble in organic solvents such as ethanol, ether, and chloroform.
Application Areas
Dye Industry: It is an important intermediate for the synthesis of various dyes, such as basic dyes and cationic dyes. These dyes are widely used in the dyeing and printing processes of the textile, leather, and paper industries, which can give products bright colors and good dyeing properties.
Pharmaceutical Industry: It is used in the synthesis of some bioactive compounds. Some derivatives have pharmacological effects such as antibacterial and antiviral activities, and have certain application value in the field of drug research and development.
Chemical Analysis: It is often used as a chromogenic agent in analytical chemistry. For example, in water quality testing, it can react with residual chlorine in water to form a red compound, and the content of residual chlorine is determined by colorimetry. It can also be used to detect other oxidizing substances, which has the characteristics of high sensitivity and good selectivity.
Other Fields: It is used as an antioxidant in the rubber industry, which can improve the antioxidant performance and service life of rubber products. It can also be used as an intermediate in organic synthesis to prepare other nitrogen - containing organic compounds.
Production Method
Usually, p - nitrochlorobenzene is used as the raw material. It first undergoes an amination reaction with dimethylamine to form N,N - dimethyl - p - nitroaniline, and then through a reduction reaction, the nitro group is reduced to an amino group to obtain N,N - dimethyl - p - phenylenediamine. The reduction reaction can be carried out by methods such as iron powder reduction and catalytic hydrogenation reduction.
Packaging, Storage, Transportation and Safety
Packaging: Generally, it is sealed and packaged in brown glass bottles or plastic bottles to prevent the product from contacting air and moisture and deteriorating. It can also be packaged in iron drums or plastic drums lined with plastic bags, and the net weight per drum is determined according to customer requirements.
Storage and Transportation: It should be stored in a cool, dry, and well - ventilated warehouse, away from fire sources and heat sources. Avoid mixing it with oxidants, acids, and other substances. During transportation, it is necessary to prevent the packaging from being damaged and the product from leaking.
Safety: N,N - Dimethyl - p - phenylenediamine is toxic to a certain extent and irritating to the skin, eyes, and respiratory tract. During use, protective gloves, goggles, and masks should be worn to avoid skin contact and inhalation of dust or vapor. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical attention in a timely manner.
