Den strukturella formeln för propylen är ch₂=ch-ch₃, som också kan förkortas till C₃h₆ .
Den grundläggande definitionen och egenskaperna för propylen R1270
Propylene is an organic compound with the chemical formula C₃H₆ and a molecular weight of 42.08. It is a colorless, slightly sweet gas that is in a gaseous state at room temperature and pressure. Propylene is flammable, produces a bright flame when burning, and has an explosion limit of 2% to 11.1% in air. Propylene is insoluble in water, but is easily soluble in organic solvents such as ethanol and ether. In addition, the melting point of propylene is -185.2℃, the boiling point is -47.4℃, and the relative density in liquid state is 0.5193. These physical properties make propylene widely used in industrial production and scientific research.
The structural formula of propylene has important application value in chemical reactions. First of all, the carbon-carbon double bond of propylene makes it an important raw material for synthesizing polymer materials. Through polymerization, propylene can generate polypropylene (PP), which is an important thermoplastic with excellent mechanical properties, chemical corrosion resistance and electrical insulation. Secondly, propylene can also generate propylene oxide through oxidation reaction, which is an important raw material for the production of polyols and polyurethanes. In addition, propylene can also be used to produce a variety of organic compounds such as acrylonitrile and propylene oxide, which are widely used in chemical, pharmaceutical, electronic and other fält .
Introduktion till den industriella beredningen och användningen av propylen R1270
Propylen produceras huvudsakligen genom processer såsom petroleumsprickor och katalytisk sprickning . Under petroleumsprickningsprocessen sönderdelas större kolväten i mindre kolväten, inklusive eten och propylen, vid höga temperaturer . Catalytic Catalys catalys till crack inlyal inlight oil inlight oil inlyal hydoc temperatures. In addition, propane dehydrogenation is also an important method for producing propylene, which converts propane into propylene and hydrogen. As an important chemical raw material, propylene has a wide range of uses. In addition to being used to produce polypropylene, propylene is also used to manufacture a variety of organic compounds such as Akrylonitril, propylenoxid, isopropanol, fenol, aceton osv. utveckla .
