Cyclopropane Cylinder

Cyclopropane (trimethylene) is a colorless combustible gas with a characteristic odor reminiscent of petroleum ether, has a pungent taste, a simple hydrocarbon, an organic substance of cycloalkane class (the chemical formula is C3H6). Cyclopropane is liquefied at temperatures from 4 to 20 °C and an increase in pressure to 5 atm, or at a temperature of -32.86 °C, it freezes at a temperature of -127.62 °C. It is highly flammable, mixtures with air, oxygen or nitrous oxide are explosive. Cyclopropane is obtained by the intramolecular Wurz reaction from ?-di alkyl halides by heating with metals (Na, Mg, Zn).

APPLICATION:

Cylinders are not hazardous cargo until they are taken into use, but in any case they should be transported in conditions that exclude mechanical damage. Cylinders filled with cyclopropane shall be transported by rail, road and water transport in accordance with the regulations on transportation of dangerous goods, applicable to the relevant mode of transport. The cylinders shall be transported in a horizontal position with gaskets between the cylinders or in a vertical position necessarily with a guard against possible falling. The cylinders must be transported with caps screwed on.

Cylinders designed for storage and transportation of cyclopropane must not be used for storage and transportation of other gases, and it is prohibited to perform any operations that may contaminate their internal surface and degrade the physical and chemical properties of the gas. It is forbidden to make any modifications to the cylinder bodies using welding or mechanical tools, which can lead to damage to the integrity or appearance of defects that degrade the technical characteristics of the cylinders. When using cylinders for cyclopropane it is not allowed to install them in the places of people passage, movement of goods and passage of vehicles. When using cyclopropane, all measures should be taken to prevent the possibility of explosion, including precautions related to the use of electrical and X-ray equipment and avoiding the generation of static electricity. When using cyclopropane, avoid releasing the gas where there is a risk of forming an explosive mixture with air. Waste gas must be burned in a suitable burner with a safety gate. All industrial premises where cyclopropane is used must be provided with ventilation that meets the requirements of GOST 12.4.021. The content of chemical substances in the air should not exceed the sanitary and hygienic standards according to GOST 12.1.005. The gas in the cylinders must not be completely consumed when in use. The residual gas pressure in the cylinder must be at least 0.05 MPa (0.5 kgf/cm2).

Cylinders filled with cyclopropane are stored in special warehouses or in outdoor areas under a shelter that protects the cylinders from precipitation and direct sunlight. Warehouses and outdoor areas must be located within the lightning protection zone. In the premises where the cylinders filled with cyclopropane are stored, it is prohibited to handle open flame; electrical networks and artificial lighting must be of explosion-proof design. Do not use tools that produce sparks on impact. Cylinders designed for transportation and storage of cyclopropane must be protected against static electricity in accordance with GOST 12.1.018. It is forbidden to store cylinders with cyclopropane and oxidizing gases and other oxidizing agents in the same room, it is forbidden to store cylinders in the room where the technological process of using cyclopropane contained in them is carried out. Storage of cylinders should be carried out with the caps screwed on.
