Isobutane (I.C4H10)

Magawo Aumisiri

Isobutane, yemwenso amadziwika kuti 2-methylpropane, ndi chinthu chopangidwa ndi mankhwala a C4H10 ndi CAS nambala 75-28-5. Ndi mpweya wosayatsa utoto, wonunkhira pang'ono pakatenthera bwino komanso mopanikizika. Ili ndi poizoni wochepa ndipo imatha kuonedwa ngati wosavutikira. Malo osungunuka: -159.4 ° C, malo otentha: -11.73 ° C, osungunuka pang'ono m'madzi, osungunuka mu ethanol, ether, etc. Makamaka amapezeka mu gasi lachilengedwe, gasi woyenga ndi mpweya wosweka, womwe umapezeka ndikudzipatula, ndi zina zambiri, amapezekanso mwa isomerization ya n-butane. Amapanga chisakanizo chophulika ndi mpweya, ndipo malire ake ndi 1.9% mpaka 8.4% (voliyumu). Ikhoza kuwotcha ndikuphulika ikayatsidwa kutentha ndi kuyatsa moto. Imachita mwamphamvu mukakumana ndi ma oxidants. Nkhuni yake imalemera kuposa mpweya ndipo imatha kufalikira mpaka patali pamalo apansi, ndipo imayamba kuyaka moto ikakumana ndi gwero lamoto. Amagwiritsidwa ntchito popanga isooctane kudzera mu alkylation ndi isobutylene, yomwe imagwiritsidwa ntchito ngati mafuta octane improver; kudzera polimbana, imatha kupanga isobutylene ndi propylene; itha kupanga alkylated ndi n-butene ndi propylene kuti apange mafuta a alkylated; itha kupanga methyl mowa. Acrylic acid, acetone, methanol, etc. Amagwiritsa ntchito kaphatikizidwe ka isooctane, ngati mafuta octane chosakanikirana, omwe amagwiritsidwa ntchito popanga isobutylene, propylene, methacrylic acid, monga refrigerant, refrigerant, etc. High-purity isobutane imagwiritsidwa ntchito ngati mpweya wokhazikika komanso kukonzekera kwa mpweya wosakanikirana wapadera. Sungani mosungira, mozizira, mozizira kosungira mpweya woyaka moto. Khalani kutali ndi magwero a moto ndi kutentha. Kutentha kosungira sikuyenera kupitirira 30 ° C. ziyenera kukhala kutali ndi oxidizer, osasunga pamodzi. Gwiritsani ntchito malo owunikira kuphulika komanso mpweya wabwino. Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimakonda kuphulika. Malo osungirako ayenera kukhala ndi zida zochiritsira zadzidzidzi.

Ntchito:

1. Amagwiritsidwa ntchito makamaka popanga isooctane mwa isomerization ndi isobutylene ngati octane nambala yosinthira mafuta. Kulimbana kungapangidwe ndi isobutylene ndi propylene. Kuphatikizika kwa n-butene ndi propylene kwa mafuta a alkylate. Methacrylic acid, acetone ndi methanol akhoza kukonzekera. Itha kugwiritsidwanso ntchito ngati firiji.

2. Kuyera kwambiri isobutane imagwiritsidwa ntchito ngati gasi wamba komanso kukonzekera chisakanizo chapadera.

3. Pofuna kaphatikizidwe ka isooctane, ngati mafuta octane nambala abwino pokonzekera isobutylene, propylene, methacrylic acid, yogwiritsidwa ntchito ngati firiji.

Phukusi Labwino:

Ubwino:

1.Fakitole yathu imatulutsa Neon kuchokera kuzinthu zopangira zapamwamba, kuphatikiza mtengo wake ndi wotsika mtengo.
2. Neon imapangidwa pambuyo pochulukitsa njira zambiri zoyeretsera ndikukonzanso mu fakitole yathu. Makina olamulira pa intaneti amatsimikizira kuti mpweya ukuyera nthawi iliyonse.
3. Pakudzazidwa, silinda iyenera kuyanika kaye kwa nthawi yayitali (osachepera 16hrs), kenako timatsuka chopukusira, pomaliza timachichotsa ndi gasi woyambirira. Njira zonsezi zimatsimikizira kuti mpweya ndi wosalala.  
4. Takhalapo m'munda wamafuta kwazaka zambiri, zokumana nazo zambiri pakupanga ndi kutumiza kunja tiyeni tipambane kukhulupilira kwa makasitomala, amakhutitsa ndi ntchito yathu ndikutipatsa ndemanga yabwino.
