Ukuminyana kwe-Ethyl Acetate: Ukuhlaziywa Okuphelele kanye Nesicelo Esisebenzayo
I-Ethyl Acetate iyi-solvent evamile yemvelo esetshenziswa ezindaweni ezihlukahlukene zezimboni nezaselabhorethri. Ukuqonda ukuminyana kwe-Ethyl Acetate akubalulekile nje kuphela ekukhiqizeni amakhemikhali, kodwa futhi kusiza ukukhulisa ukusebenza kahle kwayo ezimeni ezihlukene zohlelo lokusebenza. Kulesi sihloko, sizoxoxa ngokuminyana kwe-ethyl acetate kanye nezici ezihilelekile ukukusiza ukuthi uqonde kangcono le mpahla ebalulekile yomzimba.
Incazelo Yokuminyana Kwe-Ethyl Acetate
Ukuminyana kwe-ethyl acetate ubukhulu beyunithi ngayinye ye-ethyl acetate ezingeni lokushisa elinikeziwe nokucindezela. Ngokuvamile, ukuminyana kukalwa ngo-g/cm³ (amagremu ku-cubic sentimitha) noma kg/m³ (amakhilogremu ku-cubic mitha ngayinye). Kulabo abasebenza embonini yamakhemikhali, idatha enembayo ngokuminyana kwe-ethyl acetate ingasiza ukubala ngokunembile ukusetshenziswa kwezinto ezibonakalayo, ukuthuthukisa izinqubo nokuqinisekisa ikhwalithi yomkhiqizo.
Amanani aqondile wokuminyana kwe-ethyl acetate
Ngaphansi kwezimo ezijwayelekile (20°C, 1 atmosphere), ukuminyana kwe-ethyl acetate cishe ku-0.902 g/cm³. Leli nani lisho ukuthi i-cubic centimeter ngayinye ye-ethyl acetate inesisindo esingamagremu angu-0.902. Kubalulekile ukuqaphela ukuthi ukuminyana kuyahlukahluka nezinga lokushisa. Njengoba izinga lokushisa likhuphuka, umthamo woketshezi ngokuvamile uyakhula, okuholela ekukhuleni okuphansi. Ngakho-ke, umphumela wokushintsha kwezinga lokushisa endaweni yokusebenza kubuningi be-ethyl acetate kufanele ucatshangelwe lapho kwenziwa izibalo ezinembile.
Izinto ezithinta ukuminyana kwe-ethyl acetate
Izinga lokushisa: Izinga lokushisa lingenye yezinto eziyinhloko ezithinta ukuminyana kwe-ethyl acetate. Njengoba izinga lokushisa likhuphuka, ukunyakaza kwamangqamuzana oketshezi kuyaqina futhi umthamo uyanda, okuholela ekwehleni kokuminyana. Ngokuvamile ekukhiqizweni kwezimboni, ukuminyana kwe-ethyl acetate kuyalungiswa ngokuvumelana nokushintsha kwezinga lokushisa ukuze kuqinisekiswe ukunemba kokulinganisa.

Ukuhlanzeka: Ubuningi be-ethyl acetate buphinde buthinteke ubumsulwa bayo. Uma i-ethyl acetate ixubene nokunye ukungcola, njengamanzi noma ezinye izincibilikisi, ukuminyana kungashintsha. Ngakho-ke, ukusebenzisa ukuhlanzeka okuphezulu kwe-ethyl acetate akuqinisekisi ukuzinza kwenqubo kuphela, kodwa futhi kuphumela kudatha ethembekile yokuminyana.

Ingcindezi: Nakuba ukucindezela kunomphumela omncane uma kuqhathaniswa noketshezi, ngaphansi kwezimo zengcindezi ephezulu ukuminyana kuzokwenyuka kancane. Lokhu kufanele kucatshangelwe ezicelweni zezimboni ezinomfutho ophezulu, ikakhulukazi lapho kubandakanyeka ukusebenza okunembayo okuphezulu.

Ukusetshenziswa okusebenzayo kwe-ethyl acetate density
Embonini yamakhemikhali, ukuminyana kwe-ethyl acetate kunezinhlelo zokusebenza ezibalulekile ezindaweni eziningana. Ekwakhiweni kwemikhiqizo efana nezingubo zokunamathisela kanye ne-adhesives, idatha yokuminyana iyisisekelo sokunquma izilinganiso zezingxenye. Ezinkambisweni zokugcina nezokuthutha, ulwazi lokuminyana lusiza ukubala umthamo wesitoreji nezindleko zokuthutha zezinto. Ezinqubweni zokuhlukanisa ezifana ne-distillation, ukuminyana kuyipharamitha ebalulekile yokunquma ukuphumelela kokuhlukaniswa kwezingxube zezinto ezifanayo.
Isiphetho.
Ukuqonda ukuminyana kwe-ethyl acetate nezici eziwuthintayo kubalulekile kuzo zonke izici zokukhiqizwa kwamakhemikhali. Ngokubamba imiphumela yezinga lokushisa, ubumsulwa kanye nokucindezela kokuminyana kwe-ethyl acetate, abasebenza ngamakhemikhali bangakwazi ukulawula kangcono inqubo yokukhiqiza futhi bathuthukise ikhwalithi yomkhiqizo. Sethemba ukuthi le ndatshana izokusiza ukuthi uqonde kangcono futhi usebenzise impahla esemqoka ye-ethyl acetate ekusebenzeni okungokoqobo.
