Diaminodiphenylmethane - Introduction
Diaminodiphenylmethane (abbreviated as DDM) is an organic compound with the following properties:
1. Appearance: DDM is a colorless or light yellow solid with a special ammonia smell.
2. Solubility: DDM is soluble in some organic solvents, such as alcohols, ethers and ketones, but has low solubility in water.
3. Stability: DDM is relatively stable at room temperature, but it is not resistant to acids and oxidants.
DDM main uses are as follows:
1. Catalyst: DDM is commonly used as a hydrogen peroxide catalyst for the curing and crosslinking of polymers and rubbers.
2. Electronic Materials: DDM can be used as organic synthesis intermediates for the synthesis of liquid crystal molecules, dyes, fluorescent materials, etc.
3. Cosmetics and personal care products: DDM is used as an antibacterial agent, sunscreen and preservative.
The preparation method of DDM is generally obtained by the reaction of aniline and formaldehyde under alkaline conditions. In the laboratory, the DDM can be obtained by dissolving aniline in formaldehyde solution, adding alkaline substances such as sodium hydroxide, heating reaction and crystallization purification.
regarding the safety information of DDM, you need to pay attention to the following matters:
1. Toxicity: DDM has certain toxicity to human body and may cause irritation to respiratory system, skin and eyes.
2. Use note: when operating DDM, you need to wear appropriate personal protective equipment, such as gloves, safety glasses, etc., to prevent direct contact.
3. Storage conditions: DDM should be stored in a dry, cool, well-ventilated place, and away from fire and oxidant.
When Using DDM, please follow the relevant safety operation procedures and refer to the safety data sheet (SDS) when necessary.
