R500 - Introduction
The Dichlorodifluoromethane and difluoroethane azeotropic mixture is a common gas mixture with the chemical formula CCl2F2/C2H4F2. The following is a description of the nature, use, preparation and safety information of the azeotrope:
Nature:
1. Appearance: colorless gas.
2. Boiling point:-9.7 ℃.
3. Density: 1.31g/cm³.
4. Solubility: Soluble in some organic solvents, such as alcohols, ethers and ketones.
Use:
1. Cleaning agent: Dichlorodifluoromethane and difluoroethane azeotropic mixture is widely used in cleaning agents and solvents, such as for cleaning electronic products, metal parts and plastic products.
2. Heat Transfer Agent: because of its low boiling point and good heat transfer performance, azeotrope can be used as heat transfer agent, suitable for some electronic equipment and refrigeration system.
3. Used to make foam plastics: Azeotrope can be used to produce foam plastics, insulating materials and packaging materials.
Method:
The preparation of Dichlorodifluoromethane and difluoroethane azeotropic mixture is usually based on distillation method, which uses the different boiling points of the two components to achieve purification and separation. The specific preparation of the azeotrope needs to be carried out in a laboratory or industrial process.
Safety Information:
1. Effects on the human body: The azeotrope will cause central nervous system inhibition and suffocation risk to the human body at high concentrations. During use, it is necessary to follow relevant safety operation and protective measures to ensure good ventilation.
2. Environmental impact: azeotropes have destructive effect on atmospheric ozone and are greenhouse gases. Environmental protection regulations and guidelines need to be followed when handling and disposing of azeotropes.
IMPORTANT: The preparation and use of chemicals need to follow appropriate laboratory safety standards and procedures.
