Physical and chemical properties of cyclopentane

Chemical formula - C5H10;

Under normal conditions - a colorless liquid with a kerosene odor;

Density at 20 ° C -0.745g/cm3;

Boiling point -+49.3 ° C;

Melting point -93.9 # 176; C;

Insoluble in water, miscible with organic solvents such as ethanol.

The main way to obtain cyclopentane is to reduce cyclopentanone. It can also be prepared by oil distillation, hydrogenation of cyclopentadiene, and heating reaction of 1,5-dibromopentane with metal magnesium or zinc.

Safety for humans and the environment

Its ODP is zero and GWP is 11.

When there is a source of ignition, cyclopentane vapor can ignite at -37 ° C. When heated to+320 ° C, the gas can spontaneously ignite.

When the concentration in the air is 1.4 to 8%, cyclopentane will form an explosive mixture.

When cyclopentane enters the atmosphere, it forms photochemical smog and reacts within it, leading to the release of tropospheric ozone, which is the third largest greenhouse gas in terms of climate impact.

Application of Cyclopentane

Cyclopentane is used as foaming agent of polyurethane foam (PPU) in refrigeration equipment.

Because of its ability to form photochemical smog, cyclopentane is not used to produce open cell foam.

As a foaming agent, use pure (impurity content not exceeding 5%) or technical (impurity content not exceeding 25%) cyclopentane.

The fire and explosion hazards of this substance require the use of additional safety measures at all stages of storage, transportation, and mixing, making the implementation of this technology complex in small businesses.

In order to avoid fire or explosion, nitrogen is used in the storage tank, tundish and consumable tank instead of the usual air environment, and the opening of the refrigerator cabinet is purged (inerted) immediately before pouring polyurethane foam.
