Liquid Ethylene Density Calculator

Liquid ethylene must be kept at extremely cold temperatures and specific pressures to remain in its liquid state — the Liquid Ethylene Density Calculator gives you the precise density of ethylene under those conditions. Enter your temperature and pressure (with your choice of units) to get the density in kg/m³, along with specific weight, a converted density in your preferred unit, and the confirmed phase state.

Frequently Asked Questions

What is ethylene and its chemical formula?

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.

At what temperature and pressure is ethylene liquid?

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.

How is liquid ethylene density calculated?

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.

What is the difference between density and specific weight?

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).

Is ethylene soluble in water?

Ethylene has limited solubility in water. It's slightly soluble at low temperatures and pressures, but generally considered hydrophobic due to its hydrocarbon nature.

What are the main uses of liquid ethylene?

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.

How accurate are the calculated density values?

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.
