4,4-methylenebis (2-ISOPROPYL-6-METHYLANILINE) is an organic compound commonly abbreviated as MBDA. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: White crystalline solid
-Molecular formula: C22H28N2
-Molecular weight: 320.47g/mol
-Melting point: 125-130 ° C
-Boiling point: 394.5 ° C
-It is stable at room temperature, insoluble in water, soluble in organic solvents.
Use:
- MBDA is an antioxidant with a strong chemical composition. It is widely used in rubber, plastics, rubber adhesives, paints, coatings and other industries to improve the thermal stability and weather resistance of materials.
- MBDA can also be used as a preservative and softener in cosmetics.
Method:
The synthesis method of MBDA can be obtained by the reaction of aniline and alkylating agent. The specific steps are as follows:
1. Slowly add an alkylating agent, such as isopropyl bromide, to a solution of aniline to generate N-alkylaniline.
2. The N-alkyl Aniline reacts with a reagent that forms a methylene double bond, such as formaldehyde, to generate 4,4-methylene bis (2-alkyl aniline).
Safety Information:
- MBDA is a chemical and should be handled safely.
-Wear appropriate personal protective equipment such as chemical protective gloves, protective goggles and protective face masks during operation.
-Avoid direct contact with skin and eyes. In case of contact, rinse immediately with plenty of water and seek medical assistance.
-Store in a sealed container and store in a dry, well-ventilated place, away from fire and oxidizing agents.
