Ukuminyana kwe-Acetone: Ukuhlaziywa Kwezinto Ezibalulekile Nethonya
I-acetone, enefomula yamakhemikhali i-C₃H₆O, iyincibilikisi yemvelo esetshenziswa kabanzi ezimbonini ezihlukahlukene, esobala, eguquguqukayo, futhi enekhono eliphezulu lokuxazulula izinkinga. Impahla engokomzimba ye-acetone density isetshenziswa kakhulu emkhakheni wamakhemikhali, futhi kubalulekile ukuqonda nokulinganisa ngokunembile ukuminyana kwe-acetone ekugcinweni kwayo, ekuthuthweni nasekusetshenzisweni kwayo. Leli phepha lizohlaziya ngokuningiliziwe incazelo ye-acetone density, izici zayo ezithonya kanye nezinguquko zayo ngaphansi kwezimo ezahlukene.
Incazelo yokuminyana kwe-acetone kanye nenani elijwayelekile
Ukuminyana kwe-acetone yinqwaba ye-acetone ngevolumu yeyunithi ngayinye, ngokuvamile ku-g/cm³ noma kg/m³. Ngokusekelwe kudatha evela ezimeni ezijwayelekile, ukuminyana kwe-acetone cishe ku-0.791 g/cm³ ku-20 °C. Leli nani lilinganiswa lapho ukuhlanzeka kwe-acetone nezinga lokushisa kuzinzile, ngakho-ke ekusebenzeni ukuminyana kwe-acetone kungase kuhluke uma izimo zishintsha.
Umthelela Wezinga Lokushisa Ku-Acetone Density
Izinga lokushisa lingenye yezinto ezibalulekile ezithinta ukuminyana kwe-acetone. Njengoba izinga lokushisa likhuphuka, amabanga ama-intermolecular phakathi kwama-acetone ayanda, okuholela ekwehleni kokuminyana kwawo. Isibonelo, njengoba izinga lokushisa likhuphuka lisuka ku-20 ° C liye ku-50 ° C, ukuminyana kwe-acetone kuncipha kakhulu. Ngakho-ke, ekusetshenzisweni kwezimboni, ikakhulukazi izinqubo ezibandakanya ukulinganisa okunembile kwe-dosing kanye nokuxuba, ukuguqulwa kwe-acetone kanye nezinga lokushisa kufanele kucatshangelwe.
Ngakolunye uhlangothi, njengoba izinga lokushisa lincipha, ukunyakaza kwamangqamuzana e-acetone kuncipha futhi ukuminyana kuyanda. Emazingeni okushisa aphakeme, njengokuqandisa, ukuminyana kwe-acetone kuzoba phezulu kakhulu kunezinga lokushisa legumbi. Ukuqonda okunembile kwalezi zinguquko kubalulekile ukuze ulawule amazinga okusabela kwamakhemikhali, uthuthukise ukuncibilika nokunye ukusebenza.
Ukuminyana kwe-acetone njengomsebenzi wokuhlanzeka
Ukuhlanzeka kwe-acetone nakho kunomphumela omkhulu ekugqineni kwayo. I-acetone imvamisa idinga ukuxubaniswa namanye amakhemikhali elabhorethri noma ekukhiqizweni kwezimboni. Uma i-acetone iqukethe amanzi noma okunye ukungcola, lezi zinto zangaphandle zizoshintsha ukuminyana okuphelele kwe-acetone. Isibonelo, lapho amanzi exubene ne-acetone, ukuminyana kwengxube kuzoba phezulu kunokwe-acetone emsulwa. Ngakho-ke, kubalulekile ukuqinisekisa ukuthi i-acetone isetshenziswa ngendlela ehambisana nezidingo zenqubo ngokuhlolwa okuqinile kobumsulwa nokulawula.
Ukuqonda ukuhlukahluka kokuminyana kwe-acetone kubalulekile ekulawuleni okunembile kokugeleza koketshezi, izilinganiso zokuxuba nokusabela kwamakhemikhali ekukhiqizweni kwamakhemikhali. Ukwehluleka ukulinganisa ngokunembile kanye nokulungisa ukuminyana kwe-acetone kungaholela emaphutheni okwakheka, ukungazinzi kwe-solvent noma ukusabela kwamakhemikhali okungalingani, kuthinte ikhwalithi yomkhiqizo.
Ukubaluleka kokuminyana kwe-acetone ezimeni ezahlukahlukene zohlelo lokusebenza
I-acetone isetshenziswa kakhulu ezimbonini ezinjengopende, okokuhlanza, ukucutshungulwa kwamapulasitiki kanye nemithi. Kulezi zinhlelo zokusebenza, ukuminyana kwe-acetone kunomthelela oqondile ekusebenzeni nasekuzinzeni komkhiqizo. Isibonelo, embonini yezemithi, i-acetone ivame ukusetshenziswa ekukhishweni nasekuhlanganiseni izidakamizwa, futhi ukuhluka kokuminyana kwe-acetone kungathinta ukusebenza kahle kokukhipha kanye nokuhlanzeka kwezidakamizwa. Embonini kapende, lapho i-acetone isetshenziswa njenge-solvent, ukuminyana kwayo kuthinta i-viscosity kanye nomphumela wokumboza kapende.
Ngakho-ke, kunoma iyiphi imboni ebandakanya i-acetone, ukuqapha ngokucophelela ukuminyana kwe-acetone kungenye yezinyathelo ezibalulekile zokuqinisekisa ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza.
Ukufingqa
Ukuminyana kwe-acetone kuyipharamitha ebalulekile yomzimba ethinta ukusebenza kwayo. Izinto ezifana nezinga lokushisa nokuhlanzeka zingathinta kakhulu ukuminyana kwe-acetone, ngakho-ke ezimeni ezihlukene zohlelo lokusebenza, ukuqonda iphethini yokushintsha kokuminyana kwe-acetone kungasiza amabhizinisi ukuthi alawule kangcono inqubo yokukhiqiza futhi athuthukise ikhwalithi yomkhiqizo. Ngokuqapha ngokunengqondo nokulungisa ukuminyana kwe-acetone, singakwazi ukubhekana kangcono nezinselele ekukhiqizeni futhi sizuze ukukhiqizwa okuphephile nokuphumelelayo.
