Ethylene (C₂H₄) is the simplest alkene hydrocarbon with a carbon-carbon double bond. It can be represented as H₂C=CH₂ to show its molecular structure. It's a colorless gas at room temperature but becomes liquid under pressure or low temperature.
Ethylene is liquid between its melting point (-169.2°C) and boiling point (-103.8°C) at atmospheric pressure. At higher pressures, it can remain liquid at higher temperatures.
Liquid ethylene density is calculated using thermodynamic equations of state that account for temperature and pressure effects. The calculator uses empirical correlations based on experimental data to provide accurate density values.
Density is mass per unit volume (kg/m³), while specific weight is weight per unit volume (N/m³). Specific weight equals density multiplied by gravitational acceleration (9.80665 m/s²).
Ethylene has limited solubility in water. It's slightly soluble at low temperatures and pressures, but generally considered hydrophobic due to its hydrocarbon nature.
Liquid ethylene is primarily used as a feedstock in petrochemical plants to produce polyethylene, ethylene oxide, ethylene glycol, and other chemicals. It's also used as a refrigerant and in fruit ripening applications.
The calculator uses well-established thermodynamic correlations with typical accuracy within ±1% for normal operating conditions. Accuracy may decrease near critical conditions or extreme temperatures and pressures.
