Propylene is an organic compound with a molecular formula of C3H6. It is a colorless, odorless, and slightly sweet gas; it is flammable and will produce a bright flame when burned. The explosion limit in the air is 2% to 11%; Insoluble in water, soluble in organic solvents, it is a low-toxic substance[1].
Propylene is one of the basic raw materials for the three major synthetic materials, and the largest amount is used to produce polypropylene. In addition. Propylene can be used to prepare acrylonitrile, propylene oxide, isopropanol, phenol, acetone, butanol, octanol, acrylic acid and its esters, propylene glycol, epichlorohydrin, and synthetic glycerol [1].
