Acetylene (C2H2)
Acetylene, molecular mis C2H2, feem ntau hu ua cua thee lossis calcium carbide gas, yog tus tswv cuab tsawg tshaj plaws ntawm alkyne tebchaw. Acetylene yog xim tsis muaj xim, me ntsis tshuaj lom thiab tsis tshua muaj hluav taws kub nrog cov tshuaj loog tsis muaj zog thiab tiv thaiv oxidation los ntawm qhov kub thiab txias. -
Cov pa oxygen (O2)
Oxygen yog cov roj tsis muaj xim thiab tsis muaj ntxhiab tsw. Nws yog qhov feem ntau cov ntsiab lus ntawm oxygen. Raws li thev naus laus zis muaj kev txhawj xeeb, cov pa oxygen tau muab rho tawm los ntawm cov txheej txheem huab cua liquefaction, thiab cov pa oxygen hauv huab cua yog kwv yees li 21%. Oxygen yog cov pa roj uas tsis muaj xim thiab tsis muaj ntxhiab nrog cov tshuaj formula O2, uas yog cov feem ntau ntawm cov pa oxygen. Cov ntsiab lus melting yog -218.4 ° C, thiab qhov kub ntawm -183 ° C. Nws tsis yooj yim soluble hauv dej. Txog 30mL ntawm cov pa oxygen yog yaj hauv 1L dej, thiab cov kua oxygen yog ntuj xiav. -
Sulfur Dioxide (SO2)
Sulfur dioxide (sulfur dioxide) yog qhov feem ntau, yooj yim, thiab khaus sulfur oxide nrog cov tshuaj formula SO2. Sulfur dioxide yog cov roj tsis muaj xim thiab pob tshab nrog cov ntxhiab tsw. Soluble hauv dej, ethanol thiab ether, kua sulfur dioxide yog qhov ruaj khov, tsis muaj zog, tsis muaj hluav taws xob, thiab tsis tsim cov khoom tawg nrog huab cua. Sulfur dioxide muaj cov khoom bleaching. Sulfur dioxide feem ntau yog siv rau hauv kev lag luam rau tshuaj dawb pulp, ntaub plaub, txhob lo lo ntxhuav, kaus mom straw, thiab lwm yam. Sulfur dioxide tuaj yeem cuam tshuam kev loj hlob ntawm pwm thiab kab mob. -
Ethylene Oxide (ETO)
Ethylene oxide yog ib qho yooj yim cyclic ethers. Nws yog heterocyclic compound. Nws cov tshuaj formula yog C2H4O. Nws yog ib qho tshuaj lom carcinogen thiab ib qho tseem ceeb petrochemical khoom. Cov khoom siv tshuaj lom neeg ntawm ethylene oxide muaj zog heev. Nws tuaj yeem raug lub nplhaib-qhib ntxiv cov tshuaj tiv thaiv nrog ntau lub tebchaw thiab tuaj yeem txo cov nyiaj nitrate. -
1.3 Butadiene (C4H6) hmoov
1,3-Butadiene yog cov organic compound nrog cov tshuaj formula C4H6. Nws yog cov roj tsis muaj xim nrog cov ntxhiab tsw me ntsis thiab yooj yim rau liquefy. Nws tsis tshua muaj tshuaj lom thiab nws cov tshuaj toxicity zoo ib yam li cov ethylene, tab sis nws muaj zog khaus rau ntawm daim tawv nqaij thiab mucous daim nyias nyias, thiab muaj cov tshuaj loog nyob rau hauv siab concentrations. -
Hydrogen (H2)
Hydrogen muaj cov tshuaj formula H2 thiab molecular hnyav ntawm 2.01588. Nyob rau hauv ib txwm kub thiab siab, nws yog ib qho hluav taws kub heev, tsis muaj xim, pob tshab, tsis muaj ntxhiab thiab saj tsis muaj roj uas nyuaj rau yaj hauv dej, thiab tsis hnov mob nrog ntau yam khoom. -
Nitrogen (N2)
Nitrogen (N2) yog qhov tseem ceeb ntawm lub ntiaj teb huab cua, suav txog 78.08% ntawm tag nrho. Nws yog ib qho tsis muaj xim, tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom thiab yuav luag tag nrho inert gas. Nitrogen yog non-flammable thiab yog suav hais tias yog ib tug suffocating gas (uas yog, ua pa ntshiab nitrogen yuav deprive tib neeg lub cev ntawm oxygen). Nitrogen yog chemically inactive. Nws tuaj yeem cuam tshuam nrog hydrogen los tsim ammonia nyob rau hauv qhov kub thiab txias, siab siab thiab catalyst tej yam kev mob; nws tuaj yeem ua ke nrog oxygen los tsim nitric oxide nyob rau hauv cov xwm txheej tawm. -
Ethylene Oxide & Carbon Dioxide Mixtures
Ethylene oxide yog ib qho yooj yim cyclic ethers. Nws yog heterocyclic compound. Nws cov tshuaj formula yog C2H4O. Nws yog ib qho tshuaj lom carcinogen thiab ib qho tseem ceeb petrochemical khoom. -
Cov pa roj carbon dioxide (CO2)
Cov pa roj carbon dioxide, ib yam ntawm cov pa roj carbon monoxide, nrog rau cov tshuaj formula CO2, yog cov roj tsis muaj xim, tsis muaj ntxhiab lossis tsis muaj xim tsis muaj ntxhiab tsw nrog cov kua qaub me ntsis hauv nws cov tshuaj aqueous nyob rau hauv ib txwm kub thiab siab. Nws kuj yog ib qho khoom siv hauv tsev cog khoom roj thiab ib feem ntawm huab cua.
