Imikhiqizo
I-Methyl isobutyl ketone MIBK CAS No. 108-10-1
Izakhiwo Zomzimba Nezamakhemikhali
Lo mkhiqizo uwuketshezi olusobala olungenambala olunephunga le-camphor, mp-80℃, bp117-118℃, n20D 1.3960, ukuminyana okuhlobene 0.801, fp56℉(13℃), cishe olungancibiliki emanzini, kodwa lungenza i-azeotropes ngamanzi, iphoyinti layo elibilayo. ingu-87.9℃, equkethe amanzi angu-24.3%, equkethe i-ketone 75.7%, ingasetshenziswa ne-phenol, i-aldehyde, i-ether, i-benzene nezinye izinyibilikisi zemvelo Inhlanganisela ne-phenol, i-aldehyde, i-ether, i-organic solvents. Umkhiqizo unobuthi futhi umhwamuko ucasula amehlo nendlela yokuphefumula.

*Amapharamitha awokubhekisela kuphela. Ukuze uthole imininingwane, bheka i-COA
Uketshezi olukhanyayo olungenambala. Ngephunga le-ketone elimnandi. Ihlangana ne-ethanol, i-ether, i-acetone, i-benzene, njll. Incibilika emanzini (1-91%). Umhwamuko wawo wenza ingxube eqhumayo nomoya futhi ungabangela ukuvutha nokuqhuma lapho uhlangana nomlilo ovulekile nokushisa okuphezulu. Ingasabela ngokuqinile nge-oxidizer. Uma kushisa kakhulu, ukucindezela ngaphakathi kwesitsha kuyanda futhi kunengozi yokuqhekeka nokuqhuma. Chaza amapulasitiki athile, ama-resin kanye nerabha.
Isicelo
| Isetshenziswa njenge-ejenti yokukhipha i-waxing yamafutha okugcoba, ukulungisa i-rum, ushizi kanye nama-flavour ezithelo. I-solvent yokukhipha amafutha; I-conditioner yefilimu yombala |
Isetshenziswa njenge-intermediate yezokwelapha kanye ne-dyestuff. Isibulala-zinambuzane i-o-chlorobenzaldehyde singasetshenziswa ukulawula izibungu ezitshalweni ezomile nasezihlahleni zezithelo. I-o-chlorobenzaldehyde ingaba i-oxime ukuze ithole i-o-chlorobenzaldoxime, ukuhlanzwa okwengeziwe kungathola i-o-chlorobenzaldoxime, kokubili kuphakathi kwezidakamizwa.
Ukulungiselela
I-Methyl isobutyl ketone ingatholakala ku-industrial methyl isobutyl ketone sub-distillation.
Sebenzisa
Isihlukanisi esisebenzayo sosawoti wezinto ezingaphili, esihlukanisa i-plutonium ku-uranium, i-niobium ku-tantalum kanye ne-zirconium ku-hafnium. Ibuye isetshenziswe njenge-anticoagulant kanye ne-diluent ye-vinyl-type resins. Kuyi-solvent yephuzu lokubilisa eliphakathi nendawo. Isetshenziswa njenge-solvent ye-ejenti yokucubungula amaminerali, i-oyela dewaxing, i-ejenti yombala yamafilimu ombala, futhi isetshenziselwa njenge-solvent ye-tetracycline, i-pyrethroids ne-DDT, njll. Ibuye isetshenziswe embonini ye-organic synthesis.
Ukuphepha
Ukuhogela komuntu kungabangela ukuvinjelwa kwesistimu yezinzwa kanye ne-anesthesia. Lapho uhogela umoya kakhulu, kungashukumisa umgudu wokuphefumula futhi kubangele isicanucanu, ukuhlanza, ukuphelelwa ukudla, ubuhlungu besisu, njll. Abasebenzi kufanele bavikelwe futhi indawo yokusebenza kufanele ingene umoya. Gcina endaweni epholile, engenisa umoya. Gcina kude nomlilo nomthombo wokushisa. Vikela elangeni eliqondile. Gcina isitsha sivaliwe. Kufanele igcinwe ngokuhlukana nama-oxidizers.
