Product Name: Industrial Formaldehyde Solution  
Trade Mark: Sanren Brand  
Alternative Name: Formalin  
Molecular formula/Structural Formula:
Production Process: Formaldehyde solution is produced from oxidation of methanol with electrolytic silver as catalyst.  
Properties: Formaldehyde is a colorless transparent liquid, concentration 37%, with strong irritant, suffocative odours. Maximum concentration limit in air:5mg/m3. Formaldehyde vapor irritates mucous membrane. Concentrated formaldehyde shall cause corrosion to skin. It is easily soluble in water and alcohol with high reductibility, gradually oxidize in air to form formic acid or methanol by reduction. Formaldehyde is flammable, ignition temperature is about 300℃, auto ignition temperature is about 430℃, explosion limit 7-73%(v/v). Formaldehyde is easy to polymerize at low temperature to form insoluble white sediment.  
Grade: 37%
