Ukuhlaziywa Okuphelele Kwe-Acetonitrile Density
I-Acetonitrile, njenge-solvent yamakhemikhali ebalulekile, isetshenziswa kabanzi ekuphenduleni kwamakhemikhali okuhlukahlukene kanye nezicelo zezimboni ngenxa yezakhiwo zayo ezihlukile ze-physicochemical. Kulesi sihloko, sizohlaziya impahla eyinhloko ye-Acetonitrile density ngokuningiliziwe ukuze sikusize uqonde kangcono futhi usebenzise le nhlanganisela.
Izakhiwo Eziyisisekelo ze-Acetonitrile
I-Acetonitrile (ifomula yamakhemikhali: C₂H₃N) iwuketshezi olungenambala olunokuguquguquka okuphezulu nokuncibilika okuhle. Isetshenziswa kabanzi kwezemithi, amakhemikhali ezolimo, amakha nopende. I-acetonitrile ayiyona nje into ebalulekile ephakathi ku-organic synthesis, kodwa futhi ivame ukusetshenziswa njengesixazululi elabhorethri. Ngakho-ke, ukuqonda izici ezibonakalayo ze-acetonitrile, ikakhulukazi ukuminyana, kubalulekile ocwaningweni lwesayensi nokukhiqizwa kwezimboni.
Incazelo kanye Nesilinganiso Se-Acetonitrile Density
Ukuminyana ngokuvamile kubhekisela kusisindo ngeyunithi yevolumu yento ngayinye, futhi isisho sithi ρ = m/V, lapho u-ρ engu- density, m yisisindo, futhi V ingumthamo. Ku-acetonitrile, ukuminyana kwayo kuyinani elizinzile ekushiseni okuthile nokucindezela. Ezimweni ezijwayelekile (25°C, 1 atm), ukuminyana kwe-acetonitrile cishe ku-0.786 g/cm³. Kumele kuqashelwe ukuthi ukuminyana kwe-acetonitrile kuyashintsha ngokushisa. Ngakho-ke, ekusetshenzisweni okungokoqobo, ukuminyana kufanele kulungiswe ngokuvumelana nezimo ezithile zokusebenza.
Umphumela wezinga lokushisa kubuningi be-acetonitrile
Ukuminyana kwe-acetonitrile kuthinteka kakhulu izinga lokushisa, futhi ukuminyana kwe-acetonitrile kuyehla njengoba izinga lokushisa likhuphuka. Lokhu kungenxa yokuthi lapho izinga lokushisa likhuphuka, ukunyakaza kwamangqamuzana kuyaqina futhi ibanga phakathi kwama-molecule liyakhula, okuholela ekwandiseni umthamo kanjalo nokuncipha kokuminyana. Ngakho-ke, umthelela wezinga lokushisa ekugqileni kwe-acetonitrile udinga ukucatshangelwa ezimeni ezibandakanya i-metrology enembile noma ukusabela, ikakhulukazi phakathi nokuphendula kwamakhemikhali nokuhlukaniswa. Isibonelo, uma usebenzisa i-acetonitrile emazingeni okushisa aphezulu, ukuminyana kwayo kudinga ukulungiswa ukuze kuqinisekiswe ukunemba ezinqubweni zokuhlola noma zokukhiqiza.
Imiphumela ye-Acetonitrile Density kuzicelo
Ukuminyana kwe-acetonitrile kuthinta ukuziphatha kwayo ezinhlelweni ezincibilikisiwe ezahlukene. Njengento encibilikayo, i-acetonitrile inokuminyana okuphansi kunezinye izinyibilikisi eziningi eziphilayo, okuyivumela ukuba ibonise ukuziphatha okuhlukile kokwendlaleka ezixubeni. Ekukhishweni koketshezi oluwuketshezi kanye ne-chromatography, ukuminyana kwe-acetonitrile kunomthelela obalulekile ku-coefficient yokuhlukanisa nokuhlukana. Ngakho-ke, lapho ukhetha i-acetonitrile njenge-solvent, umphumela wokuminyana kwayo kuyo yonke inqubo yamakhemikhali udinga ukucatshangelwa ngokugcwele ukuze kuzuzwe imiphumela engcono kakhulu.
Isifinyezo
Ngokuhlaziya okuphelele kokuminyana kwe-acetonitrile, siyaqonda ukuthi ukuminyana kuyisici esibalulekile esithinta ukusetshenziswa kwe-acetonitrile. Ukwazi ukuminyana kwe-acetonitrile kanye nomthetho wayo wokushintsha ngezinga lokushisa kungasisiza ukuthi silawule kangcono futhi sithuthukise inqubo yokukhiqiza amakhemikhali. Ocwaningweni nasekusetshenzisweni kwesikhathi esizayo, kuyafaneleka ukucabangela ukuminyana kwe-acetonitrile njengepharamitha ebalulekile ukuze kuqinisekiswe ukunemba kokuhlolwa kanye nekhwalithi yemikhiqizo.
