China Butane What is R-600 n-butane锛?/strong The R-600 refrigerant, also known as R600, is an organic substance, a common alkane, a colorless gas that is liquefiable at room temperature and pressure, and has the chemical formula C4H10. Chinese name Butane (n-butane), English name n-butane. R600 is a hydrocarbon refrigerant with a negligibly small greenhouse effect and no impact on the ozone layer. It is now the refrigerant that is most environmentally friendly. Nearly all nations in the world utilize R600 refrigerant in new refrigeration equipment, which is beneficial for the environment. There are no restrictions on the initial installation of R600 refrigerant on new refrigeration equipment and the use of after-sales maintenance. 聽 Refrigerant nameR-600 boiling point锛?atm锛夛紝鈩?/p -0.5ODP0 saturated vapor pressure锛?5鈩冿級锛孧Pa0.117GWP锛?00 yr20 Critical temperature锛屸剝151.9combustionflammable critical pressure锛孧Pa3.79ASHRAE Security LevelA3 聽 Properties of n-butane 1.

They must be kept out of direct sunlight, heat sources, and fire when being stored. They should only be lightly loaded and unloaded while handling them to avoid damaging attachments like cylinders and valves. They are often kept in a cool, dry, and ventilated warehouse. 聽 R-600 is in favor of using refrigeration oil. The manufacturers of refrigeration compressors and refrigeration (air-conditioning) equipment should be consulted regarding the refrigerating machine oil used with R-600 refrigerant. Alternatively, a refrigeration unit with the same design specifications should be used in accordance with the unique circumstances surrounding the refrigeration compressor and refrigeration equipment. 聽 In addition to being used as a fuel directly, n-butane is also a refrigerant, a subcritical extraction solvent for biotechnology, and a starting material for organic synthesis. Butane is catalytically dehydrogenated to make butene or butadiene in the presence of a catalyst. Butane is also isoformed in the presence of sulfuric acid or anhydrous hydrofluoric acid to produce isobutane. Isobutane can also be employed as an alkylating agent. create branched chain hydrocarbons with effective antiknock characteristics by reacting with olefins. 聽 Maleic anhydride, acetic acid, acetaldehyde, and other compounds can be created by catalytic butane oxidation. Halogenation, nitration, high-temperature catalysis, and steam transformation can also produce carbon disulfide and halogenated butane. Butane can also be used to manage volatile components in motor fuel blends, as a deasphalting agent in the refinement of heavy oils, as a refrigerant for fresh water and olefins, as a Gehler polymerization solvent, etc. 聽 Measures For Combating Fires Carbon monoxide and carbon dioxide are dangerous combustion products. Cut off the gas supply to put out the fire. Extinguishing the flame at the leak is not permitted if the gas source cannot be shut off. Move the container away from the flames and into an open location to cool it with water spray. Extinguishing agents include dry powder, foam, carbon dioxide, and spray water. 聽 Spill Treatment Urgent Quickly remove the staff from the contaminated area where the spill occurred to an area upwind, isolate them, and carefully control access. Remove the cause of the fire. Emergency personnel are advised to wear anti-static overalls and self-contained positive pressure respirators. As much as you can, stop the leak at the source. To stop gas from entering, cover sewers and other nearby areas with industrial covers or absorbent materials. Accelerate the diffusion with reasonable ventilation. Utilize water mist to dilute and dissolve. To contain the massive volume of wastewater produced, build dikes or dig pits. If at all possible, direct the gas leak to an area with an exhaust fan or set up a burn nozzle to burn the gas. Leakage containers should be properly disposed of, repaired and inspected before reuse. 聽 Moving And Storing Handling Airtight functioning and complete ventilation are precautions. Operators are required to complete special training and adhere to the operating protocols to the letter. Operators are advised to wear anti-static overalls, self-priming filter gas masks (half masks), and chemical safety goggles. Avoid heat and fire sources, and smoking is not permitted in the workplace. Use equipment and ventilation systems that are explosion-proof. Stop gas from leaking into the air at the workplace. Stay away from halogens and oxidizing substances. To avoid static electricity, cylinders and containers must be grounded and bridged during the transfer procedure. Lightly load and unload when transporting to avoid damaging the cylinders and accessories. equipped with the appropriate kinds and numbers of fire-fighting and leak-treatment emergency equipment. 聽 Storage Precautions: 鈼?Keep in a cold, well-ventilated warehouse. 鈼?Stay clear from sources of heat and fire. 鈼?Both the storage temperature and the relative humidity should not be more than 30鈩?and 80%, respectively. 鈼?It should not be stored with halogens or oxidants; they should be kept apart. 鈼?Lighting and ventilation systems that are explosion-proof are used. 鈼?Use of mechanical instruments and equipment that is prone to sparking is forbidden. 鈼?Emergency leak remediation equipment should be available in the storage area. 聽聽 Transportation Precautions: 鈼?The pressure-resistant liquefied gas company's own tanker must be used to transport this product over rails within the allotted time frame, and it must be submitted to the appropriate department for permission prior to shipment. 鈼?The safety helmet that is attached to the steel cylinder must be worn whilst being transported in it. 鈼?The bottle mouths should all face in the same direction and cannot be crossed. 鈼?The height should not be higher than the vehicle's guardrail, and it should be secured with a triangular wooden pad to prevent rolling. Steel cylinders are often put flat. 鈼?The transport truck must have the appropriate sizes and types of firefighting supplies while it is in motion. 鈼?It is prohibited to load and unload this object using mechanical equipment or spark-prone tools, and the exhaust pipe of the vehicle transporting it must be fitted with a fire suppression system. 鈼?Mixing and transporting with oxidants and halogens is absolutely prohibited. 鈼?To avoid exposure to the sun in the summer, it should be moved in the morning and evening. 鈼?During stops, stay away from heat and fire sources. 鈼?Follow the route specified and avoid staying in residential or heavily crowded areas when transporting by road. 鈼?Slipping is prohibited when being transported by rail. 聽China Butane website:http://www.julychem.com/butane/
