Ethylene, a colorless gas, carries a distinct hydrocarbon odor with a trace of sweetness when in small quantities.
It’s highly flammable, featuring an ignition temperature of 425°C, an upper explosion limit of 36.0%, and a lower limit of 2.7%. When ethylene blends with air, it creates a volatile mixture capable of exploding. Exposure to open flames, intense heat, or oxidizers triggers combustion and explosion.
