MDA - Introduction
Nature:
1. It is a solid compound that appears white to light yellow.
2. It is a relatively stable compound with high melting and boiling points.
3. It has low solubility in water, but good solubility in organic solvents.
Usage:
1. Mainly used as an intermediate in polyimide resins.
2. This compound is commonly used as a crosslinking agent for hard polyurea formaldehyde resins in industry, for the preparation of high-temperature and corrosion-resistant industrial coatings, adhesives, and plastics.
Method:
Usually formed by the reaction of aniline and formaldehyde under alkaline conditions. Firstly, aniline is oxidized to resorcinol in alkaline solution. Then, resorcinol undergoes a condensation reaction with formaldehyde to produce the target product 4,4 '- diaminodiphenylmethane. The reaction process should be carried out under appropriate temperature and pH conditions.
Security information:
1. Has high toxicity and carcinogenicity.
2. Long term exposure or inhalation of this compound may pose a health hazard.
3. During use, it is necessary to strictly follow safety operating procedures, wear personal protective equipment, and ensure good ventilation.
4. Avoid contact with skin and avoid inhaling its vapors.
5. When storing and handling this compound, it should be kept away from fire and heat sources to avoid fire and explosion accidents.
