High purity propane is an organic compound, also known as propane, with a chemical formula of CH3CH2CH3. It is a colorless and odorless gas, slightly soluble in water, soluble in ethanol and ether. Here is a detailed introduction to high purity propane R290:
1. Basic properties
Molecular weight: 44.0956
Melting point: -187.6℃
Boiling point: -42.1℃ (some data -42.2℃)
Density: 1.83kg/m³ (gas)
Flash point: -104℃
Water solubility: slightly soluble
Critical temperature: 96.67℃
Critical pressure: 4.24MPa
2. Main uses
Coolant: High purity propane R290 is widely used as a coolant due to its excellent refrigeration performance, especially in small refrigeration equipment such as central air conditioners, heat pump air conditioners, and household air conditioners.
Organic synthesis raw materials: In the chemical industry, R290 can also be used as an organic synthesis raw material to participate in various chemical reactions.
3. Environmental protection characteristics
High purity propane R290 is a hydrocarbon refrigerant that has no destructive effect on the ozone layer, and its ODP (ozone depletion potential) is 0.
Compared with HFC substances, the GWP (global warming coefficient) value of R290 is very low, close to zero, and it has no destructive effect on the ozone layer, and its impact on the greenhouse effect is also minimal.
4. Safety precautions
High purity propane R290 is flammable and explosive, so special attention should be paid to safety during use.
When handling high purity propane R290, the source of leakage should be cut off as much as possible to prevent liquid from entering drains, sewers, etc., and prevent gas diffusion from causing suffocation.
If combustion occurs, appropriate fire extinguishing agents should be used to extinguish the fire.
