I-Isopropanol Density: Ukuqonda kanye Nesicelo Sayo Embonini Yamakhemikhali
I-Isopropanol, eyaziwa nangokuthi i-isopropyl alcohol noma i-IPA, iyinhlanganisela evamile ye-organic esetshenziswa ezinhlobonhlobo zamakhemikhali, amakhemisi nezimonyo. Kulesi sihloko, sizobheka kabanzi isihloko sokuminyana kwe-isopropanol ukuze sikusize uqonde ngokugcwele le mpahla ebonakalayo kanye nokubaluleka kwayo ezinhlelweni zokusebenza zomhlaba wangempela.
Kuyini Isopropyl Alcohol Density?
Ukuminyana kwe-isopropyl alcohol yinqwaba ye-isopropyl alcohol ngevolumu yeyunithi, ngokuvamile evezwa ngamagremu nge-cubic centimeter ngayinye (g/cm³). Ukuminyana kuyipharamitha ebalulekile ezintweni ezibonakalayo zoketshezi, oluthintwa izinga lokushisa nokucindezela. Ngaphansi kwezimo ezijwayelekile (20°C, 1 atm), ukuminyana kwe-isopropanol cishe ku-0.785 g/cm³. Leli nani lingahluka ngokwezinga lokushisa, ngakho-ke kubalulekile ukuqonda futhi ulungise ukuminyana kwe-isopropyl alcohol kuzimo ezihlukene zohlelo lokusebenza.
Ukubaluleka kwe-Isopropyl Alcohol Density
Ukulinganisa okunembile kokuminyana kwe-isopropyl alcohol kubalulekile ekukhiqizeni amakhemikhali nasekusetshenzisweni kwayo. Ukuminyana akuthinti kuphela isilinganiso sengxube, kodwa futhi kuhlobene ngokuqondile nokusebenza kahle kokusabela kanye nekhwalithi yomkhiqizo. Isibonelo, ekuphenduleni kwamakhemikhali, ukuminyana kwe-isopropanol kungase kuthinte i-viscosity yesisombululo, okubuye kuthinte ukudluliswa kwesisindo kanye namazinga okuphendula. Ukwazi ukuminyana kwe-isopropanol kusiza ukukhulisa amapharamitha wenqubo nokuqinisekisa ukuthi ukusabela kungenzeka ngaphansi kwezimo ezifanele.
Ukuhlukahluka kwe-isopropanol kwabantu emazingeni okushisa ahlukene
Njengoba kushiwo ngaphambili, ukuminyana kwe-isopropanol kuncipha njengoba izinga lokushisa likhuphuka. Lokhu kungenxa yokuthi ukwanda kwezinga lokushisa kubangela ukuba ibanga phakathi kwama-molecule likhule, okunciphisa ukuminyana koketshezi. Ikakhulukazi, ku-20°C, i-isopropyl alcohol inokuminyana okungu-0.785 g/cm³, kuyilapho ku-40°C, ukuminyana kwayo yehla kuya cishe ku-0.774 g/cm³. Lokhu kwehluka kubaluleke kakhulu emikhakheni emihle yamakhemikhali, eyekhemisi neye-biotechnology, lapho ukunemba kwempahla eluhlaza kubaluleke kakhulu futhi izinguquko ezincane ekuminyana zingaba nomthelela omkhulu emkhiqizweni wokugcina.
Ungakala kanjani futhi ulungise ukuminyana kotshwala be-isopropyl
Ukulinganisa ukuminyana kwe-isopropanol kuvame ukwenziwa kusetshenziswa ibhodlela elithile lamandla adonsela phansi noma i-densitometer yedijithali. Ngokwenza, ukulawula okunembile kokuminyana kwe-isopropanol kungafinyelelwa ngokulungisa izinga lokushisa noma isilinganiso sokuxuba. Ngezinqubo zamakhemikhali ezidinga ukunemba okuphezulu, kuwumkhuba ojwayelekile ukuqapha ukuminyana ngesikhathi sangempela nokwenza izinguquko ngokufanele. Lokhu akuthuthukisi ukukhiqiza kuphela, kodwa futhi kuqinisekisa ikhwalithi yomkhiqizo nokuvumelana.
Isifinyezo
Ukuminyana kwe-Isopropanol kuyipharamitha ebonakalayo eyinhloko embonini yamakhemikhali futhi inemithelela ehlukahlukene ekusetshenzisweni okungokoqobo. Ukuqonda ukuminyana kwe-isopropanol kanye nezakhiwo zayo ezincike kumazinga okushisa kubalulekile ekwandiseni inqubo yokukhiqiza nokuthuthukisa ikhwalithi yomkhiqizo. Ekukhiqizeni amakhemikhali, ukulawulwa okunembile kokuminyana kwe-isopropanol kungaletha ukusebenza kahle okuphezulu nokusebenza komkhiqizo ozinzile. Ngakho-ke, ukuqonda okujulile nokusebenzisa kahle le parameter kuzoletha izinzuzo ezibalulekile zokuncintisana ezinkampanini zamakhemikhali.
