Ukuminyana kwe-Acetonitrile: Izinto Ezithonya kanye Nemininingwane Yezindawo Zokusebenza
I-Acetonitrile iyincibilikiseli ebalulekile esetshenziswa kakhulu kumakhemikhali, imithi, kanye nezicelo zocwaningo lwaselabhorethri. Ukuqonda ukuminyana kwe-Acetonitrile kubalulekile ekugcinweni kwayo, ekuthuthweni nasekusetshenzisweni kwayo ezinhlelweni ezahlukahlukene. Kulesi sihloko, sizohlaziya ulwazi lokuminyana kwe-Acetonitrile ngokuningiliziwe, futhi sixoxe ngezici zayo ezinomthelela kanye nezicelo ezisebenzayo.
Iyini i-Acetonitrile Density?
Ukuminyana kwe-acetonitrile ubukhulu beyunithi ngayinye ye-acetonitrile ezingeni lokushisa elithile kanye nokucindezela. Ukuminyana kungenye yamapharamitha abonakalayo abalulekile wokukhombisa izici zento, ngokuvamile evezwa ngo-g/cm³ noma kg/m³. Ukuminyana kwe-acetonitrile cishe ku-0.786 g/cm³ ngaphansi kwesimo esijwayelekile esingu-20℃. Leli nani liyashintshashintsha ngokushintsha kwezinga lokushisa, ngakho-ke ukuminyana kudinga ukulungiswa futhi kubalwe ngokufanele ngaphansi kwezimo zezinqubo ezihlukene.
Ithonya lokushisa kubuningi be-acetonitrile
Izinga lokushisa liyisici esibalulekile esithinta ukuminyana kwe-acetonitrile. Njengoba izinga lokushisa likhuphuka, ukunyakaza kwamangqamuzana e-acetonitrile kuyaqina, okuholela ekwandeni kwevolumu yayo futhi ngaleyo ndlela ukuminyana kuncipha. Ngakolunye uhlangothi, lapho izinga lokushisa liyancipha, ukunyakaza kwamangqamuzana e-acetonitrile kunciphisa, ivolumu iyancipha futhi ukuminyana kuyanda. Isibonelo, uma i-acetonitrile ifudunyezwa ukusuka ku-20°C kuya ku-50°C kungcindezi yomoya, ukuminyana kwayo kungase kwehle kuze kufike ku-0.776 g/cm³. Ngakho-ke, kubalulekile ukubamba ngokunembile umthelela wezinga lokushisa kubuningi be-acetonitrile ezikhathini ezibandakanya ukulinganisa okunembayo nokulawulwa kwezimo zokusabela.
Ukusetshenziswa kwe-Acetonitrile Density embonini
Idatha enembile ye-acetonitrile density inomthelela oqondile ekukhiqizweni kwezimboni. Isibonelo, ohlelweni lokubuyisela i-solvent, ukuhluka kokuminyana kungasetshenziswa njengesisekelo sokulawulwa kwemingcele yenqubo ukuze kuthuthukiswe izinga lokutholwa kwe-solvent. Embonini yezemithi, ukulawula ukuminyana kwe-acetonitrile kusiza ukuqinisekisa ukuzinza kokuhlanzeka kwe-solvent ngesikhathi sokulungiswa kwezidakamizwa, okubuye kuthinte ikhwalithi yomkhiqizo wokugcina. Ngesikhathi sokuthutha nokugcinwa, ukuminyana kwe-acetonitrile nakho kuyinkomba ebalulekile yereferensi yokunquma ukukhethwa kweziqukathi nezindlela zokuphepha.
Ungalinganisa kanjani ukuminyana kwe-acetonitrile?
Ziningi izindlela zokukala ukuminyana kwe-Acetonitrile, ezivamile yindlela ethize yebhodlela lamandla adonsela phansi, indlela ye-buoyancy kanye nendlela ye-oscillating tube. Indlela ngayinye inobubanzi bayo bokusebenzisa kanye nezidingo zokunemba. Isibonelo, i-Specific Gravity Bottle Method ifaneleka ukulinganisa okunembile ngaphansi kwezimo zaselabhorethri, kuyilapho i-Oscillating Tube Method isetshenziswa kabanzi ukuze kunqunywe ngokushesha ezindaweni zezimboni. Lezi zindlela zokulinganisa zinikeza onjiniyela bezinqubo ukusekelwa kwedatha okubalulekile ukuze kuqinisekiswe ukuzinza kwenqubo yokukhiqiza kanye nekhwalithi ephezulu yomkhiqizo.
Isiphetho
Ukuminyana kwe-acetonitrile kuyipharamitha ebalulekile yomzimba ethinta ngokuqondile ukusebenza kwayo ezinhlelweni ezihlukahlukene zezimboni nezamasivivinyo. Ukuqonda nokuba ingcweti komthetho oshintshayo wokuminyana kwe-acetonitrile, ikakhulukazi umthelela wezinga lokushisa kuwo, kubaluleke kakhulu ekwenzeni inqubo ibe ngcono, kuqinisekiswe ikhwalithi yomkhiqizo nokusebenza okuphephile. Sithemba ukuthi ngokuhlaziywa okuningiliziwe kulesi sihloko, ungakuqonda kangcono ukubaluleka kokuminyana kwe-acetonitrile futhi usebenzise ngokunengqondo ulwazi oluhlobene emsebenzini ongokoqobo.
