CAS No. 74-85-1 Ethylene Supplier. Cov yam ntxwv ntawm Ethylene
CAS Naj Npawb 74-85-1 sib raug rau Ethylene, cov roj tsis muaj xim, nplaim taws uas ua lub luag haujlwm tseem ceeb hauv kev lag luam petrochemical thiab cov nroj tsuag biology. Nov yog cov yam ntxwv tseem ceeb ntawm Ethylene:
Cov roj formula: C2H4
Lub cev lub cev: Ntawm qhov ntsuas kub thiab siab, ethylene yog roj.
Molecular Luj: Kwv yees li 28.05 g / mol.
Boiling Point: -103.7 ° C (-154.66 ° F) ntawm 1 cua.
Melting Point: -169.2 ° C (-272.56 ° F).
Ceev: Nyob ib ncig ntawm 1.18 kg / m³ ntawm STP, me ntsis sib zog dua huab cua.
Solubility: me ntsis soluble nyob rau hauv dej thiab soluble nyob rau hauv feem ntau cov organic solvents.
Flammability thiab Reactivity: Cov nplaim hluav taws kub heev thiab tuaj yeem tsim cov khoom tawg nrog cua. Reacts nrog halogens, oxidizers, thiab muaj zog acids.
Kev siv Ethylene:
** Kev lag luam Petrochemical**: Ethylene yog lub tsev thaiv tseem ceeb hauv kev tsim cov tshuaj lom neeg ntau thiab cov yas, suav nrog polyethylene (lub ntiaj teb cov yas siv ntau tshaj plaws), ethylene glycol (siv los tiv thaiv kab mob thiab polyester fibers), thiab ethylene oxide (siv los ua. detergents thiab plastics).
Kev Ua Liaj Ua Teb: Siv los ua tus neeg sawv cev ripening rau txiv hmab txiv ntoo thiab raws li kev loj hlob regulator nyob rau hauv horticulture vim nws lub luag hauj lwm raws li ib tug natural cog hormone, txhawb cov txiv hmab txiv ntoo ripening, paj senescence, thiab abscission.
Kev tsim khoom: Siv rau hauv kev tsim cov yas chloride (rau PVC), styrene (rau polystyrene), thiab lwm yam tshuaj organic.
Kev txiav txim siab txog kev nyab xeeb:
Kev phom sij hluav taws kub thiab tawg: Ethylene cov nplaim taws kub hnyiab yuav tsum ua raws li kev tiv thaiv hluav taws thiab kev ua pa kom zoo thaum tuav thiab khaws cia.
Toxicity: Kev raug mob ntev ntev tuaj yeem ua rau kiv taub hau, mob taub hau, thiab asphyxiation hauv qhov chaw tsis muaj oxygen.
Environmental Impact: Thaum ethylene nws tus kheej tawg sai sai hauv cov huab cua, nws cov khoom siv thiab kev siv ua rau lub tsev cog khoom pa tawm tsis ncaj los ntawm kev siv hluav taws xob thiab kev tsim cov tshuaj muaj feem xyuam.
Qhov chaw muab khoom:
Cov neeg muag khoom ntawm ethylene feem ntau suav nrog cov tuam txhab petrochemical loj thiab cov tuam txhab faib roj tshwj xeeb hauv kev lag luam roj. Cov neeg muag khoom no feem ntau muaj kev sib koom ua ke uas suav nrog kev rho tawm ntawm ethylene los ntawm cov roj av los yog cov nkev roj, nws cov purification, thiab faib rau cov neeg siv khoom ntawm cov kav dej, tankers, lossis lub tog raj kheej, nyob ntawm seb muaj pes tsawg thiab kev siv kawg. Thaum muab ethylene, nws yog ib qho tseem ceeb rau kev koom tes nrog cov neeg muag khoom muaj npe nrov uas ua raws li cov qauv kev nyab xeeb thiab ib puag ncig, ua kom cov khoom lag luam zoo thiab kev coj ua lub luag haujlwm.
