Propene is an organic compound. The specific information is as follows:

1. Chemical properties: The chemical formula of propylene is C3H6. The molecular structure contains a carbon-carbon double bond and belongs to the olefin class of compounds.

2. Physical properties: Propylene is a colorless gas at room temperature and pressure, with a slight aromatic smell (some say it is slightly sweet), with a lower density than air, insoluble in water, and easily soluble in ethanol and ether. Propylene is flammable and explosive, and will produce bright flames when burning. The explosion limit in air is 2% to 11.1%.

3. Uses: Propylene is one of the three basic raw materials for synthetic materials, and the largest amount is used to produce polypropylene. In addition, propylene can also be used to prepare acrylonitrile, propylene oxide, isopropanol, phenol, acetone, butanol, octanol, acrylic acid and its esters, propylene glycol, epichlorohydrin and synthetic glycerol. Propylene is oxidized to produce propylene oxide, which is an important raw material for the production of polyols and polyurethanes. Polyurethane is widely used in the production of foam plastics, coatings, adhesives and elastomers. Propylene can also be used to produce isopropyl alcohol, acrylic acid and acrylic esters. Isopropyl alcohol is an important solvent and cleaning agent, widely used in the pharmaceutical and cosmetic industries. Acrylic acid and its esters are important raw materials for the production of coatings, adhesives and textiles.

4. Health risks: Propylene is irritating to the nose and throat. High concentrations of contact may cause lung changes. It is irritating to the skin and can cause burns. Eye contact can cause burns and permanent damage. Long-term contact may cause damage to the lungs, liver and kidneys. It is sensitizing to the skin. After sensitization, even contact with extremely low levels of methacrylic acid can cause skin itching and rashes.

In general, propylene is an important chemical raw material that is widely used in many fields.
