异丁烷 (CAS No.75-28-5)
- 物化性质
- 熔点-159.4℃，沸点-11.7℃。微溶于水，可溶于乙醇、乙醚等。与空气形成爆炸性混合物，爆炸极限为1.9%~8.4%（体积）。蒸气比空气重，能在较低处扩散到相当远的地方，遇火源会着火回燃。临界温度134.9℃，临界压力3.65MPa。破坏臭氧潜能值0。外观为无色无异臭不浑浊。
- 纯度
- 99.9%

Product Name:Isobutane
English Name:Isobutane
CAS No.:75-28-5
Aliases:R600A, 2-methylpropane
Molecular Formula:C4H10
Physical Properties:Melting point -159.4°C, boiling point -11.7°C. Slightly soluble in water, soluble in ethanol, ether, etc. Forms explosive mixtures with air, explosion limit 1.9%–8.4% (by volume). Vapor is heavier than air, can spread to distant areas at low levels and will ignite and flash back on contact with an ignition source. Critical temperature 134.9°C, critical pressure 3.65 MPa. Ozone depletion potential 0. Appearance is colorless, no odor, not turbid.
Uses:Mainly used in the alkylation with isobutene to produce isooctane, serving as an octane improver for gasoline. Also used as a refrigerant.
Technical Specifications:
Purity: 99.9%
Moisture: ≤20PPM
Sulfur content: ≤1PPM
Acidity: ≤1PPM
Evaporation residue: ≤100PPM
