Isobutane (I.C4H10)

Amapharamitha wezobuchwepheshe

Isobutane, eyaziwa nangokuthi i-2-methylpropane, iyinto ephilayo enefomula yamakhemikhali ye-C4H10 kanye nenombolo ye-CAS engu-75-28-5. Kuyinto igesi engenambala, evuthayo kancane ngaphansi kwezinga lokushisa nokucindezela okujwayelekile. Inobuthi obuphansi futhi ingathathwa njenge-asphyxiant elula. Iphuzu lokuncibilika: -159.4 ° C, iphoyinti elibilayo: -11.73 ° C, encibilikayo kancane emanzini, encibilikayo ku-ethanol, i-ether, njll. Ikakhulu ikhona kugesi wemvelo, igesi yokuhluza kanye negesi eqhekekile, etholwe ngokuhlukana ngokomzimba, njll. futhi itholakale ngokwenza isomerization kwe-n-butane. Kwakha ingxube eqhumayo nomoya, kanti umkhawulo wokuqhuma ngu-1.9% kuye ku-8.4% (ivolumu). Ingasha futhi iqhume lapho ivezwa emithonjeni yokushisa namalangabi avulekile. Iphendula ngodlame lapho ixhumana nama-oxidants. Umhwamuko wayo usinda kakhulu kunomoya futhi ungasakazekela ebangeni elithile endaweni engezansi, futhi uzokheleka lapho uhlangabezana nomthombo womlilo. Isetshenziselwa ikakhulukazi ukukhiqiza i-isooctane ngokusebenzisa i-alkylation ne-isobutylene, esetshenziswa njenge-petroli octane improver; ngokuqhekeka, ingaveza i-isobutylene ne-propylene; ingafakwa i-alkylated ne-n-butene ne-propylene ukukhiqiza uphethiloli one-alkylated; ingakhiqiza i-methyl alcohol. I-Acrylic acid, i-acetone, i-methanol, njll. Kusetshenziswa ekuhlanganisweni kwe-isooctane, njenge-octane improver, esetshenziselwa ukukhiqizwa kwe-isobutylene, i-propylene, i-methacrylic acid, njenge-refrigerant, i-refrigerant, njll. I-high-purity isobutane isetshenziswa kakhulu njenge igesi ejwayelekile kanye nokulungiswa kwegesi ekhethekile exubile ejwayelekile. Gcina endaweni yokugcina epholile, enomoya ukuze uthole amagesi avuthayo. Hlala kude nemithombo yomlilo nokushisa. Ukushisa kwesitoreji akufanele kudlule u-30 ° C. kufanele igcinwe kude ne-oxidizer, ungagcini ndawonye. Sebenzisa izindawo zokukhanyisa ezifakwayo nezindawo zokungenisa umoya. Akuvunyelwe ukusebenzisa imishini yokusebenza kanye namathuluzi athambekele enhlakeni. Indawo yokugcina kufanele ifakwe imishini yokwelashwa okuphuthumayo.

Isicelo:

1. Isetshenziselwa ngokukhethekile ukukhiqizwa kwe-isooctane nge-isomerization nge-isobutylene njengenombolo ye-octane eyenza ngcono uphethiloli. Ukuqhekeka kungenziwa nge-isobutylene ne-propylene. I-alkylation ye-n-butene ene-propylene kuphethiloli we-alkylate. I-Methacrylic acid, i-acetone ne-methanol ingalungiswa. Futhi ingasetshenziswa njengesiqandisi.

2. Ukuhlanzeka okuphezulu i-isobutane isetshenziswa kakhulu njengegesi ejwayelekile kanye nokulungiswa kwengxube ekhethekile ejwayelekile.

3. Ngokuhlanganiswa kwe-isooctane, njengenombolo ye-octane ephuculisayo yokulungiselela i-isobutylene, i-propylene, i-methacrylic acid, esetshenziswa njengesiqandisi.

Iphakheji ejwayelekile:

Izinzuzo:

1. Ifektri yethu ikhiqiza i-Neon kusuka kuzinto ezibonakalayo zekhwalithi ephezulu, ngaphandle kwentengo ishibhile.
2. INeon ikhiqizwa ngemuva kwezinqubo eziningi zokuhlanzwa nokulungiswa efektri yethu.Isistimu yokulawulwa kwe-inthanethi iqinisekisa ubumsulwa begesi kuzo zonke izigaba.Umkhiqizo ophelile kufanele uhlangabezane nezinga.
3. Ngesikhathi sokugcwaliswa, isilinda kufanele somiswe isikhathi eside (okungenani ama-16hrs), bese siyasusa isilinda, ekugcineni siyisuse ngegesi yoqobo.Zonke lezi zindlela ziqinisekisa ukuthi igesi ayihlanzekile kusilinda.  
4.Sibe khona emkhakheni weGesi iminyaka eminingi, ulwazi olucebile ekukhiqizeni nasekuthekeleni masiphumelele ukuthembela kwamakhasimende, bayanelisa ngensizakalo yethu futhi basinikeze ukuphawula okuhle.
