Izici Zomkhiqizo:
1.Ixubene nezinyibilikisi eziningi eziphilayo njenge-ethanol, i-ether, i-benzene kanye namafutha ezilwane nawemifino.Kuyi-solvent enhle kakhulu ye-cellulose nitrate, i-polyvinyl chloride, i-polyvinyl acetate, i-polystyrene, i-epoxy resin, irabha yemvelo neyokwenziwa, i-DDT, i-2,4-D nezinto eziningi eziphilayo.Ingakhiwa ibe isixazululo esiphansi se-viscosity ukuvimbela i-gelation.
2.Izakhiwo zamakhemikhali: Iqembu le-carbonyl ku-molecule kanye nama-athomu e-hydrogen angomakhelwane acebile ngokusebenza kabusha kwamakhemikhali, izakhiwo zamakhemikhali ezifana ne-butanone.Isibonelo, uma i-oxidised ngama-oxidising agents aqinile njenge-chromic acid, ikhiqiza i-acetic, i-isobutyric acid, i-isovaleric acid, i-carbon dioxide namanzi.I-Catalytic hydrogenation inikeza i-4-methyl-2-pentanol.Umkhiqizo ongeziwe ukhiqizwa nge-sodium bisulfite.Ukujiya nezinye izinhlanganisela ze-carbonyl phambi kwe-catalyst eyisisekelo.Ukujiya nge-hydrazine ukwenza i-hydrazone kanye ne-Claisen condensation reaction nge-ethyl acetate.
3.Ukuzinza: Ukuzinza
4.Izinto ezingavunyelwe:Sama-oxidants aqinile,ejenti yokunciphisa enamandla, izisekelo eziqinile
5.Ingozi yePolymerization:I-Non-pi-olymerization
Isicelo somkhiqizo:
1.Lo mkhiqizo ungasetshenziswa njenge-solvent yazo zonke izinhlobo zezingubo zezimboni, kanye ne-solvent yokukhiqiza amapende aphezulu ezimoto, ama-inks, amakhasethi, amateyipu wevidiyo nokunye.Ibuye isetshenziswe njenge-ore dressing agent, i-oyela dewaxing ejenti kanye ne-ejenti yombala yefilimu yombala.
2.Iphinde ibe nokuncibilika okuhle kakhulu kwezinhlanganisela ze-organometallic.I-peroxide yalo mkhiqizo iyisiqalisi esibalulekile ekuphenduleni kwe-polymerisation yama-polyester resins.Iphinde isetshenziswe njenge-solvent ku-organic synthesis kanye nokuhlaziywa kwe-atomic ukumuncwa kwe-spectrophotometric.
3.Isetshenziswa kakhulu njenge-solvent.Ngaphezu kwenani elikhulu lopende, ama-strippers kapende, izinhlobonhlobo zama-resin zokwenziwa njenge-solvent, kodwa futhi asetshenziswa njengezinamathiselo, i-DDT, i-2,4-D, i-pyrethroids, i-penicillin, i-tetracycline, iglue yenjoloba, ukuhlaziywa kwe-atomic ukumuncwa kwe-spectrophotometric i-solvent.
4.Iphinde ibe nokuncibilika okuhle kakhulu kwezinhlanganisela ze-organometallic.Ibuye isetshenziswe njenge-ore dressing agent, i-oyela dewaxing ejenti kanye ne-ejenti yombala yefilimu yombala.Kukhona futhi nosawoti wezinto ezingaphili isihlukanisi esisebenzayo, singahlukaniswa ku-uranium plutonium, i-niobium ku-tantalum, i-zirconium ne-hafnium, njll. I-MIBK peroxide iyisiqalisi esibalulekile ekuphenduleni kwe-polyester resin polymerisation.
5.Isetshenziswa njenge-reagent yokuhlaziya, njengamazinga wokuhlaziya i-chromatographic.Ibuye isetshenziswe njengama-solvents, ama-extraction agents.
6.Isetshenziswa ekwenzeni i-nail polish ezimonyoni.Kucwecwe lwezinzipho njengendawo encibilikisayo yephoyinti eliphakathi nendawo (100~140°C), okunikeza ukucwebezela kwezinzipho ukuthi kusabalale, kuvimbe umuzwa ongacacile.
I-7.Isetshenziswa njenge-solvent yopende we-spray, i-nitrocellulose, i-fiber ethers ethile, i-camphor, i-grease, irabha yemvelo kanye neyokwenziwa.
Amanothi Okugcina Umkhiqizo:
1.Gcina endaweni epholile, nengena umoya.
2. Gcina kude nomlilo kanye nomthombo wokushisa.
3.Izinga lokushisa lokugcina akufanele lidlule ku-37°C.
4.Gcina isitsha sivaliwe.
5.Kufanele igcinwe ngokuhlukana nama-oxidizing agents,ukunciphisa ama-alkalis nama-ejenti,futhi akufanele neze ixutshwe.
6.Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.
7.Vimbela ukusetshenziswa kwemishini namathuluzi alula ukwenza izinhlansi.
I-8.Indawo yokugcina kufanele ifakwe imishini yokwelapha izimo eziphuthumayo ezivuzayo kanye nezinto zokukhosela ezifanele.
