 The railway transportation time limit of this product is to be shipped in a tanker provided by the pressure-resistant liquefied gas enterprise, and the relevant department must be approved before shipment. The safety helmet on the cylinder must be worn when transporting in a rigid bottle. Steel cylinders are generally placed flat, and the mouth of the cylinder should be in the same direction without crossing; the height should not exceed the protective fence of the vehicle, and the triangular wooden pad should be used to secure it to prevent rolling. The transportation vehicles should be equipped with corresponding types and quantities of fire-fighting equipment during transportation. The exhaust pipe of the vehicle carrying the item must be equipped with a fire arrester, and it is prohibited to use mechanical equipment and tools that are prone to sparks for loading and unloading. Mixed shipment and transportation with oxidants, halogens, etc. is strictly prohibited. In summer, it should be transported in the morning and evening to prevent sun exposure. Stay away from fire and heat sources during stopovers. When transporting by road, follow the prescribed route and do not stop in residential or densely populated areas. It is forbidden to drop off during railway transportation
In addition to being directly used as fuel, n-butane is also used as a subcritical biotechnology extraction solvent, refrigerant and organic synthesis raw material. Butane is dehydrogenated to butene or butadiene in the presence of a catalyst, and isomerized to isobutane in the presence of sulfuric acid or anhydrous hydrofluoric acid, isobutane is catalytically dehydrogenated to isobutene, isobutane can be used as an alkylating agent Reacts with olefins to produce branched chain hydrocarbons with good anti-knock properties. Catalytic oxidation of butane can produce maleic anhydride, acetic acid, acetaldehyde, etc.; halobutane can be produced by halogenation; nitrobutane can be produced by nitration; carbon disulfide can be produced by catalysis at high temperature; Can produce hydrogen. In addition, butane can also be used as a motor fuel blend to control volatile components; it can also be used as a heavy oil refining deasphalting agent; a wax precipitation agent in oil wells; an overflow agent for secondary oil recovery, a resin foaming agent, and seawater conversion Refrigerant for fresh water, as well as olefin agent Gele polymerization solvent, etc. [3]
Mixed with propane as liquefied petroleum gas, it is widely used in household heating, cooking and industrial heating. In addition, it is widely used as a raw material for organic synthesis. For example, butene and butadiene can be produced by dehydrogenation; isobutane can be produced by isomerization; maleic anhydride, acetic acid, acetaldehyde, etc. can be produced by catalytic oxidation; halogenated butane can be produced by halogenation; Nitrification can produce nitrobutane; catalysis can produce carbon disulfide at high temperature, and hydrogen can be produced by steam reforming. Used in organic synthesis and ethylene manufacturing, as a raw material for synthetic rubber and high-octane liquid fuels, as household fuels, solvents, and refrigerants, and also for instrument calibration.
