Uses: This product is an important chemical raw material. Propylene chloride obtained by chlorination of propylene can be further synthesized into allyl alcohol, propylene dichloropropanol, chloropropionitrile, etc., which are used to produce glycerol, epoxy resin, chlorohydrin rubber, surfactants, etc.; propylene alkylation to obtain isopropylbenzene, which is currently the main intermediate of phenol, and acetone is produced simultaneously in the production of phenol; propylene is synthesized by carbonylation to obtain n-butyraldehyde and isobutyraldehyde, which can be derived into many organic synthesis intermediates, which are used in plasticizers, dyes, solvents, pesticides, etc.; propylene hydration to obtain isopropyl alcohol, which is used to produce acetone, isopropylamine and isopropyl esters; propylene dimerization to obtain ethylene, trimerization to obtain benzene, polymerization to obtain polypropylene, and propylene tetramerization to obtain dodecene, which is an intermediate of surfactants.

Packaging method:
Package according to the method recommended by the manufacturer, such as: open steel drums. Ampoules or ordinary wooden boxes. Screw-mouth glass bottles, iron-capped glass bottles, plastic bottles or metal barrels (cans) or ordinary wooden boxes.

Storage： 

Store in a cool, ventilated warehouse.

The warehouse temperature should not exceed 37°C.

It should be stored separately from oxidants and edible chemicals, and should not be mixed (see Part 10 for prohibited incompatibility).

Keep the container sealed.

Keep away from fire and heat sources.

Lightning protection equipment must be installed in the warehouse.

The exhaust system should be equipped with a grounding device to remove static electricity.

Use explosion-proof lighting and ventilation settings.

It is prohibited to use equipment and tools that are prone to sparks.

The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials.
