I-Allene, kunye nefomula yeekhemikhali i-C3H4 kunye nenombolo ye-CAS 463-49-0, igesi engenambala kunye nencasa emnandi kancinane. Ayinyibiliki emanzini, inyibilika kancinane kwi-ethanol, kodwa inyibilika ngokulula kwi-ether. Indawo yokunyibilika ye Allene yi -136 ° C, indawo yokubila yi -34 ° C, kunye noxinzelelo yi-0.647 g/cm ³. Ubuninzi bayo bomphunga yi-1.42 (malunga nomoya kwi-20 ° C), uxinzelelo lomphunga ngu-6795 mm Hg (21 ° C), kunye ne-refractive index yi-1.4169. Iimeko zokugcina ezicetyiswayo ziphakathi kwe-2-8 ° C. Umda wokuqhuma kwe-Allene yi-13%.
Ngokokhuseleko, i-Allene ihlelwa njengerhasi enokutsha kwaye ileyibhile yezinto ezinobungozi nguF+, F, Ikhowudi yecandelo lengozi yi-R12. Inombolo yayo yokuthutha impahla eyingozi yi-UN 2200 2.1, eyeKlasi 2.1 yempahla eyingozi.
I-Allene isetyenziswa njengento ebalulekileyo ekrwada kwi-organic chemistry, ngakumbi njengendawo ephakathi kwi-organic synthesis. Inokulungiselelwa ukusuka kwi-olefins ngokusabela kweekhemikhali ezithile, njengokongeza i-dibromocarbon kwi-olefins kwaye emva koko isebenzisa ukucutha isinyithi esisebenzayo.
Okwangoku, kukho iintlobo ezahlukeneyo zokuhlanjululwa kweemveliso ze-Allene ezikhoyo kwimarike, ukusuka kwi-95% ukuya kwi-99.99%. Iindlela zokupakisha nazo zenziwe ngokweemfuno zabasebenzisi, kubandakanywa neebhotile kunye neemveliso ezinkonkxiweyo ezinezakhono ezahlukeneyo.
Iqela lethu lophando liquka iqela labasebenzi abanamava kunye nabanobuchule abanolwazi olubanzi kunye nezakhono zobungcali kwiinkalo zeegesi ezikhethekileyo kunye ne-isotopes ezinzile. Ngokwenza izinto ezintsha eziqhubekayo kunye neenzame zophando kunye nophuhliso, sithe gqolo ukusungula umgangatho ophezulu kunye neemveliso ezicocekileyo ukuze sihlangabezane neemfuno eziguqukayo zabathengi bethu.
Umzi-mveliso wethu uxhotyiswe ngezixhobo zemveliso zanamhlanje kunye neenkqubo ezingqongqo zokuvelisa ukuqinisekisa ukuzinza nokuthembeka kweemveliso zethu. Sigxile ekukhuselweni kwendalo kunye nophuhliso oluzinzileyo, sizibophelele ekunciphiseni impembelelo kokusingqongileyo kunye nokuthobela imigaqo kunye nemigangatho efanelekileyo.
