:) What are the physical and chemical properties and uses of isobutane? English name: isobutane; Chinese name 2: 2-methylpropane; English name 2: 2-methylpropane; Molecular formula: C4H10; Molecular weight: 58.12. Physical and chemical properties of isobutane: Main component: pure substance; Appearance and characteristics: colorless gas with a slight odor. Melting point (°C): -159.6 ； Boiling point (°C): -11.8 Relative density (water=1): 0.56 ； Relative vapor density (air=1): 2.01 Saturation vapor pressure (kPa): 160.09 (0°C) Heat of combustion (kJ/mol): 2856.6 Critical temperature (°C): 135 ； Critical pressure (MPa): 3.65 Flash point (°C): -82.8 ； Ignition temperature (°C): 460 Upper explosion limit (%/V/V): 8.5 ； Lower explosion limit % (V/V): 1.8 Solubility: Slightly soluble in water, soluble in ether. Main uses: Used in dyes, chemically synthesized refrigerants, synthetic rubber, aviation gasoline, and lighting. In the plants that use Belgium’s Ineos low-pressure slurry process to produce high-density polyethylene, isobutane is primarily used as a solvent diluent. Health hazards: It has a mild irritating and ** effect. Acute poisoning: The main symptoms include headache, dizziness, drowsiness, nausea, and a state similar to drunkenness; in severe cases, coma may occur. Chronic effects: headache, dizziness, poor sleep, and easy fatigue. Flame and explosion hazard: This product is flammable. Hazardous characteristic: Flammable gas. When mixed with air, it can form an explosive mixture, and there is a risk of combustion and explosion in the presence of heat sources or open flames. Reacts violently upon contact with oxidizers. Its vapor is heavier than air, allowing it to spread over considerable distances at lower levels; it will catch fire and reignite when exposed to a source of flame. :loveliness:
