Acetylene yog cov roj tsis muaj xim, me ntsis lom thiab yooj yim hlawv nrog cov tshuaj loog thiab tiv thaiv kev oxidation tsis muaj zog nyob rau hauv qhov kub thiab txias ib txwm muaj. -
Cov pa oxygen (O2)
Oxygen yog ib hom pa roj uas tsis muaj xim thiab tsis muaj ntxhiab. Nws yog hom pa roj uas feem ntau siv. Raws li thev naus laus zis, pa roj yog rho tawm los ntawm cov txheej txheem ua kua hauv huab cua, thiab pa roj hauv huab cua muaj li ntawm 21%. Pa roj yog ib hom pa roj tsis muaj xim thiab tsis muaj ntxhiab nrog cov mis tshuaj O2, uas yog hom pa roj feem ntau siv. Lub ntsiab lus yaj yog -218.4 ° C, thiab lub ntsiab lus npau yog -183 ° C. Nws tsis yooj yim yaj hauv dej. Kwv yees li 30 mL ntawm pa roj yaj hauv 1 L dej, thiab cov pa roj ua kua yog xiav ntuj. -
Cov pa roj sulfur dioxide (SO2)
Sulfur dioxide (sulfur dioxide) yog cov sulfur oxide uas feem ntau, yooj yim tshaj plaws, thiab ua rau khaus nrog cov tshuaj formula SO2. Sulfur dioxide yog cov roj tsis muaj xim thiab pob tshab nrog cov ntxhiab tsw qab. Yaj hauv dej, ethanol thiab ether, cov kua sulfur dioxide yog qhov ruaj khov, tsis ua haujlwm, tsis kub hnyiab, thiab tsis tsim cov khoom sib xyaw nrog huab cua. Sulfur dioxide muaj cov khoom ua kom dawb. Sulfur dioxide feem ntau siv hauv kev lag luam los ua kom cov pulp, wool, silk, straw kaus mom, thiab lwm yam. Sulfur dioxide kuj tseem tuaj yeem tiv thaiv kev loj hlob ntawm pwm thiab cov kab mob. -
Ethylene Oxide (ETO)
Ethylene oxide yog ib qho ntawm cov cyclic ethers yooj yim tshaj plaws. Nws yog ib qho heterocyclic compound. Nws cov mis tshuaj yog C2H4O. Nws yog ib qho tshuaj lom carcinogen thiab yog ib qho khoom lag luam petrochemical tseem ceeb. Cov khoom siv tshuaj ntawm ethylene oxide yog cov khoom siv heev. Nws tuaj yeem dhau los ua cov tshuaj tiv thaiv ntxiv nrog ntau cov tshuaj thiab tuaj yeem txo cov nyiaj nitrate. -
1,3 Butadiene (C4H6)
1,3-Butadiene yog ib qho organic compound nrog cov mis tshuaj C4H6. Nws yog ib qho roj tsis muaj xim nrog me ntsis tsw qab thiab yooj yim rau liquefy. Nws tsis muaj tshuaj lom thiab nws cov tshuaj lom zoo ib yam li ethylene, tab sis nws muaj kev khaus rau daim tawv nqaij thiab cov ntaub so ntswg, thiab muaj cov nyhuv anesthetic ntawm cov concentration siab. -
Hydrogen (H2)
Hydrogen muaj cov mis tshuaj ntawm H2 thiab qhov hnyav molecular ntawm 2.01588. Nyob rau hauv qhov kub thiab txias ib txwm muaj, nws yog ib qho roj uas yooj yim hlawv, tsis muaj xim, pob tshab, tsis muaj ntxhiab thiab tsis muaj saj uas nyuaj rau yaj hauv dej, thiab tsis cuam tshuam nrog feem ntau cov tshuaj. -
Nitrogen (N2)
Nitrogen (N2) yog ib feem tseem ceeb ntawm huab cua hauv ntiaj teb, suav txog 78.08% ntawm tag nrho. Nws yog ib qho roj tsis muaj xim, tsis muaj ntxhiab, tsis muaj saj, tsis muaj tshuaj lom thiab yuav luag tsis muaj zog kiag li. Nitrogen tsis yooj yim kub hnyiab thiab suav tias yog ib qho roj uas ua rau tuag taus (uas yog, kev ua pa nitrogen ntshiab yuav ua rau tib neeg lub cev tsis muaj oxygen). Nitrogen tsis ua haujlwm hauv tshuaj. Nws tuaj yeem ua rau hydrogen ua rau ammonia nyob rau hauv qhov kub thiab txias, siab siab thiab cov xwm txheej catalyst; nws tuaj yeem sib xyaw nrog oxygen los ua nitric oxide nyob rau hauv cov xwm txheej tso tawm. -
Cov Khoom Sib Xyaws Ethylene Oxide & Carbon Dioxide
Ethylene oxide yog ib qho ntawm cov cyclic ethers yooj yim tshaj plaws. Nws yog ib qho heterocyclic compound. Nws cov mis tshuaj yog C2H4O. Nws yog ib qho tshuaj lom carcinogen thiab yog ib yam khoom tseem ceeb hauv petrochemical. -
Cov pa roj carbon dioxide (CO2)
Cov pa roj carbon dioxide, ib hom pa roj carbon oxygen, nrog rau cov mis tshuaj CO2, yog cov pa roj tsis muaj xim, tsis muaj ntxhiab lossis tsis muaj xim uas muaj saj qaub me ntsis hauv nws cov kua dej hauv qab qhov kub thiab txias ib txwm muaj. Nws kuj yog cov pa roj av uas feem ntau siv rau hauv tsev cog khoom thiab yog ib feem ntawm huab cua.
