Cyclopentane should be stored in a cool and ventilated warehouse. Keep away from kindling and heat sources. The storage temperature should not exceed 29 ℃. Keep container sealed. It shall be stored separately from oxidant and shall not be mixed. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area shall be equipped with leakage emergency treatment equipment and appropriate storage materials.
Cyclopentane is widely used to replace freon, which is widely used in refrigerators and freezers; Foaming agent for rigid PU foam. Cyclopentane as a building block in the synthesis of a variety of compounds, including plastics, resins, and other industrial chemicals It is used as solvent for solution polymerization of polyisoprene rubber and cellulose ether and standard material for chromatographic analysis. It is also used as a refrigerant.
