PARAFORMALDEHYDE, chemical formula (CH2O)n, is a high molecular compound formed by the condensation reaction of formaldehyde molecules. It has the following properties:
1. Structural stability: PARAFORMALDEHYDE has a high degree of molecular stability and can resist acid, alkali and degradation.
2. Physical properties: PARAFORMALDEHYDE appears as a colorless or yellowish solid with a high degree of transparency and luster.
3. Thermal stability: paraformalhyde has high thermal stability and can maintain its structure and properties at high temperatures.
4. Chemical resistance: PARAFORMALDEHYDE has good resistance to most chemicals, but it will corrode under the action of strong acids and oxidants.
The main uses of paraformalhyde include:
1. Furniture manufacturing: PARAFORMALDEHYDE is commonly used in the manufacture of wooden furniture, man-made plates, etc.
2. Automotive industry: PARAFORMALDEHYDE can be used in automotive interior parts, engine parts and adhesives.
3. Textiles: paraformalhyde can be used as an anti-wrinkle finishing agent and fire retardant for textiles.
The methods of preparing PARAFORMALDEHYDE are mainly as follows:
1. Urea-Formaldehyde method: PARAFORMALDEHYDE is prepared by polycondensation reaction of Urea and Formaldehyde.
2. Amine manufacturing method: PARAFORMALDEHYDE is prepared by reacting formaldehyde and amine.
3. Acid catalyzed polymerization method: using acid catalyst to catalyze the polymerization reaction of formaldehyde molecules.
When using PARAFORMALDEHYDE, you need to pay attention to the following safety information:
1. PARAFORMALDEHYDE is an organic compound with certain toxicity and irritation. During use and preparation, attention should be paid to protective measures to avoid contact with skin, eyes and respiratory tract.
2. PARAFORMALDEHYDE can release harmful gases, such as formaldehyde, at high temperatures. Ensure that the operating environment is well ventilated to avoid inhalation of harmful gases.
3. When storing PARAFORMALDEHYDE, keep away from fire and combustibles, and ensure that the storage container is well sealed to prevent volatilization and leakage.
4. When disposing of abandoned PARAFORMALDEHYDE, it should be disposed of in accordance with relevant laws and regulations to avoid environmental pollution.
