Mpweya woyaka umagawidwa m'magulu awiri: mpweya umodzi woyaka ndi mpweya wosakanikirana woyaka, womwe uli ndi mawonekedwe oyaka komanso ophulika. Kuchuluka kwa mpweya woyaka ndi mpweya wofanana ndi mpweya woyaka ndi mpweya wothandizira kuyaka womwe umayambitsa kuphulika motsatira miyezo yovomerezeka. Mpweya wothandizira kuyaka ukhoza kukhala mpweya, mpweya wa okosijeni kapena mpweya wina wothandizira kuyaka.

Malire ophulika amatanthauza malire a kuchuluka kwa mpweya woyaka kapena nthunzi mumlengalenga. Mpweya woyaka wochepa kwambiri womwe ungayambitse kuphulika umatchedwa malire otsika ophulika; kuchuluka kwakukulu kumatchedwa malire apamwamba ophulika. Malire ophulika amasiyana malinga ndi zigawo za chisakanizocho.

Mpweya woyaka ndi wophulika wamba ndi hydrogen, methane, ethane, propane, butane, phosphine ndi mpweya wina. Mpweya uliwonse uli ndi makhalidwe osiyana komanso malire osiyana a kuphulika.

Haidrojeni

Haidrojeni (H2)Ndi mpweya wopanda mtundu, wopanda fungo, komanso wopanda kukoma. Ndi madzi opanda mtundu pa kutentha kwambiri komanso kutentha kochepa ndipo amasungunuka pang'ono m'madzi. Ndi woyaka kwambiri ndipo ukhoza kuphulika mwamphamvu ukasakanikirana ndi mpweya ndikumenyana ndi moto. Mwachitsanzo, ukasakanikirana ndi chlorine, ukhoza kuphulika mwachilengedwe pansi pa dzuwa; ukasakanikirana ndi fluorine mumdima, ukhoza kuphulika; haidrojeni mu silinda imathanso kuphulika ikatenthedwa. Malire a kuphulika kwa haidrojeni ndi 4.0% mpaka 75.6% (kuchuluka kwa voliyumu).

Methane

MethaneNdi mpweya wopanda mtundu, wopanda fungo loipa wokhala ndi kutentha kwa -161.4°C. Ndi wopepuka kuposa mpweya ndipo ndi mpweya woyaka womwe ndi wovuta kwambiri kusungunuka m'madzi. Ndi chinthu chosavuta chachilengedwe. Kusakaniza kwa methane ndi mpweya moyenerera kumaphulika kukakumana ndi spark. Malire apamwamba a kuphulika % (V/V): 15.4, malire otsika a kuphulika % (V/V): 5.0.

Ethane

Ethane siisungunuka m'madzi, imasungunuka pang'ono mu ethanol ndi acetone, imasungunuka mu benzene, ndipo imatha kupanga zosakaniza zophulika ikasakanikirana ndi mpweya. Ndikoopsa kuyaka ndi kuphulika ikakumana ndi magwero a kutentha ndi malawi otseguka. Idzapanga zotsatira zamphamvu za mankhwala ikakhudzana ndi fluorine, chlorine, ndi zina zotero. Malire ophulika apamwamba % (V/V): 16.0, malire ophulika otsika % (V/V): 3.0.

Propani

Propane (C3H8), mpweya wopanda mtundu, ungapange zosakaniza zophulika ukasakanikirana ndi mpweya. Ndi woopsa kuyaka ndi kuphulika ukakumana ndi magwero otentha ndi malawi otseguka. Umayankha mwamphamvu ukakhudzana ndi ma oxidants. Malire ophulika apamwamba % (V/V): 9.5, malire ophulika otsika % (V/V): 2.1;

N.butane

n-Butane ndi mpweya woyaka wopanda mtundu, wosasungunuka m'madzi, wosungunuka mosavuta mu ethanol, ether, chloroform ndi ma hydrocarbon ena. Umapanga chisakanizo chophulika ndi mpweya, ndipo malire a kuphulika ndi 19% ~ 84% (madzulo).

Ethylene

Ethylene (C2H4) ndi mpweya wopanda mtundu wokhala ndi fungo labwino lapadera. Umasungunuka mu ethanol, ether ndi madzi. Ndi wosavuta kuyaka ndi kuphulika. Zinthu zomwe zili mumlengalenga zikafika pa 3%, zimatha kuphulika ndi kuwotcha. Malire a kuphulika ndi 3.0 ~ 34.0%.

Asetilini

Acetylene (C2H2)Ndi mpweya wopanda mtundu wokhala ndi fungo la ether. Umasungunuka pang'ono m'madzi, umasungunuka mu ethanol, ndipo umasungunuka mosavuta mu acetone. Ndi wosavuta kuyaka ndi kuphulika, makamaka ukakhudzana ndi phosphides kapena sulfides. Malire a kuphulika ndi 2.5-80%.

Propylene

Propylene ndi mpweya wopanda mtundu wokhala ndi fungo labwino ngati uli wabwinobwino. Umasungunuka mosavuta m'madzi ndi acetic acid. Ndi wosavuta kuphulika ndi kuwotcha, ndipo malire a kuphulika ndi 2.0 ~ 11.0%.

Cyclopropane

Cyclopropane ndi mpweya wopanda mtundu womwe umakhala ndi fungo la petroleum ether. Umasungunuka pang'ono m'madzi ndipo umasungunuka mosavuta mu ethanol ndi ether. Ndi wosavuta kuyaka ndi kuphulika, ndipo malire ake ndi 2.4 ~ 10.3%.

1,3 Butadiene

1,3 Butadiene ndi mpweya wopanda mtundu komanso wopanda fungo, wosasungunuka m'madzi, wosasungunuka mosavuta mu ethanol ndi ether, komanso wosungunuka mu yankho la cuprous chloride. Ndi wosakhazikika kwambiri kutentha kwa chipinda ndipo umawola mosavuta ndikuphulika, ndi malire a kuphulika a 2.16 ~ 11.17%.

Methyl chloride

Methyl chloride (CH3Cl) ndi mpweya wopanda mtundu, womwe umasungunuka mosavuta. Umakoma bwino ndipo uli ndi fungo lofanana ndi la ether. Umasungunuka mosavuta m'madzi, ethanol, ether, chloroform ndi glacial acetic acid. Ndi wosavuta kuyaka ndi kuphulika, ndipo malire ake ndi 8.1 ~ 17.2%.
