Igesi evuthayo ihlukaniswe ibe yigesi eyodwa evuthayo kanye negesi evuthayo exubile, enezici zokuba evuthayo futhi eqhumayo. Inani elilinganiselwe lokuhlushwa kwengxube efanayo yegesi evuthayo kanye negesi esekela ukusha ebangela ukuqhuma ngaphansi kwezimo ezijwayelekile zokuhlola. Igesi esekela ukusha ingaba umoya, umoya-mpilo noma amanye amagesi asekela ukusha.

Umkhawulo wokuqhuma ubhekisela emkhawulweni wokuhlushwa kwegesi evuthayo noma umhwamuko emoyeni. Okuqukethwe okuphansi kakhulu kwegesi evuthayo okungabangela ukuqhuma kubizwa ngokuthi umkhawulo wokuqhuma ophansi; ukuhlushwa okuphezulu kakhulu kubizwa ngokuthi umkhawulo wokuqhuma ophezulu. Umkhawulo wokuqhuma uyahlukahluka ngokwezingxenye zengxube.

Amagesi avamile avuthayo naqhumayo ahlanganisa i-hydrogen, i-methane, i-ethane, i-propane, i-butane, i-phosphine kanye namanye amagesi. Igesi ngayinye inezakhiwo ezahlukene kanye nemikhawulo yokuqhuma.

I-hydrogen

I-Hydrogen (H2)iyigesi engenambala, engenaphunga, engenambitheki. Iwuketshezi olungenambala uma lucindezelekile kakhulu futhi lushisa kancane futhi luncibilika kancane emanzini. Luvutha kakhulu futhi lungaqhuma ngamandla uma luxubene nomoya bese luhlangana nomlilo. Isibonelo, uma luxubene ne-chlorine, lungaqhuma ngokwemvelo ngaphansi kwelanga; uma luxubene ne-fluorine ebumnyameni, lungaqhuma; i-hydrogen esilinda nayo ingaqhuma uma ishiswa. Umkhawulo wokuqhuma kwe-hydrogen uphakathi kuka-4.0% kuya ku-75.6% (ukuhlushwa kwevolumu).

I-Methane

I-Methaneiyigesi engenambala, engenaphunga enezinga lokubila elingu--161.4°C. Ilula kunomoya futhi iyigesi evuthayo okunzima kakhulu ukuyincibilikisa emanzini. Ingumxube olula wezinto eziphilayo. Ingxube ye-methane nomoya ngesilinganiso esifanele izoqhuma uma ihlangana nenhlansi. Umkhawulo ophezulu wokuqhuma % (V/V): 15.4, umkhawulo ophansi wokuqhuma % (V/V): 5.0.

U-Ethane

I-Ethane ayincibiliki emanzini, incibilika kancane ku-ethanol kanye ne-acetone, incibilika ku-benzene, futhi ingakha izingxube eziqhumayo uma ixutshwe nomoya. Kuyingozi ukushisa nokuqhuma lapho kuvezwa emithonjeni yokushisa kanye namalangabi avulekile. Kuzokhiqiza ukusabela kwamakhemikhali okunamandla lapho kuhlangana ne-fluorine, i-chlorine, njll. Umkhawulo wokuqhuma ophezulu % (V/V): 16.0, umkhawulo wokuqhuma ophansi % (V/V): 3.0.

I-Propane

I-propane (C3H8), igesi engenambala, ingakha izingxube eziqhumayo uma ixutshwe nomoya. Kuyingozi ukushisa nokuqhuma lapho ivezwa emithonjeni yokushisa kanye namalangabi avulekile. Isabela ngamandla uma ithintana nama-oxidants. Umkhawulo wokuqhuma ophezulu % (V/V): 9.5, umkhawulo wokuqhuma ophansi % (V/V): 2.1;

I-N.butane

I-n-Butane iyigesi evuthayo engenambala, engancibiliki emanzini, incibilika kalula ku-ethanol, i-ether, i-chloroform kanye namanye ama-hydrocarbon. Yakha ingxube eqhumayo nomoya, futhi umkhawulo wokuqhuma u-19% ~ 84% (kusihlwa).

I-Ethylene

I-Ethylene (C2H4) iyigesi engenambala enephunga elimnandi elikhethekile. Incibilika ku-ethanol, i-ether kanye namanzi. Kulula ukuyishisa nokuqhuma. Uma okuqukethwe emoyeni kufinyelela ku-3%, ingaqhuma futhi ishe. Umkhawulo wokuqhuma u-3.0 ~ 34.0%.

I-Acetylene

I-Acetylene (C2H2)iyigesi engenambala enephunga le-ether. Incibilika kancane emanzini, incibilika ku-ethanol, futhi incibilika kalula ku-acetone. Kulula kakhulu ukuyishisa nokuqhuma, ikakhulukazi uma ihlangana nama-phosphide noma ama-sulfide. Umkhawulo wokuqhuma u-2.5 ~ 80%.

I-Propylene

I-Propylene iyigesi engenambala enephunga elimnandi esimweni esijwayelekile. Incibilika kalula emanzini kanye ne-acetic acid. Kulula ukuqhuma nokusha, kanti umkhawulo wokuqhuma u-2.0 ~ 11.0%.

I-Cyclopropane

I-Cyclopropane iyigesi engenambala enephunga le-petroleum ether. Incibilika kancane emanzini futhi incibilika kalula ku-ethanol naku-ether. Kulula ukuyishisa nokuqhuma, ngomkhawulo wokuqhuma ongu-2.4 ~ 10.3%.

1,3 I-Butadiene

1,3 I-Butadiene iyigesi engenambala futhi engenaphunga, ayincibiliki emanzini, incibilika kalula ku-ethanol kanye ne-ether, futhi incibilika kusisombululo se-cuprous chloride. Ayizinzile kakhulu ekushiseni kwegumbi futhi ibola kalula futhi iqhume, ngomkhawulo wokuqhuma ongu-2.16 ~ 11.17%.

I-Methyl chloride

I-Methyl chloride (CH3Cl) iyigesi engenambala, encibilika kalula. Inambitheka kamnandi futhi inephunga elifana ne-ether. Incibilika kalula emanzini, i-ethanol, i-ether, i-chloroform kanye ne-glacial acetic acid. Kulula ukuyishisa nokuqhuma, ngomkhawulo wokuqhuma ongu-8.1 ~ 17.2%.
