Izici Zomkhiqizo:
I-1.I-hydrolysed kancane kancane phambi kwamanzi ukukhiqiza i-acetic acid ne-propanol.Ijubane le-hydrolysis liyi-1/4 yalelo le-ethyl acetate.Lapho i-propyl acetate ishiselwa ku-450 ~ 470℃, ngaphezu kokukhiqiza i-propylene ne-acetic acid, kukhona i-acetaldehyde, i-propionaldehyde, i-methanol, i-ethanol, i-ethane, i-ethylene namanzi.Ebukhoneni be-nickel catalyst, eshiselwe ku-375 ~ 425 ℃, ukukhiqizwa kwe-carbon monoxide, i-carbon dioxide, i-hydrogen, i-methane ne-ethane.I-chlorine, i-bromine, i-hydrogen bromide ne-propyl acetate zisabela emazingeni okushisa aphansi.Uma kusabela nge-chlorine ngaphansi kokukhanya, ama-85% e-monochloropropyl acetate akhiqizwa phakathi namahora ama-2.Kulokhu, 2/3 kukhona 2-chloro esikhundleni futhi 1/3 kukhona 3-chloro esikhundleni.Lapho kukhona i-aluminium trichloride, i-propyl acetate ishiselwa nge-benzene ukuze yakhe i-propylbenzene, i-4-propylacetophenone ne-isopropylbenzene.
2.Ukuzinza: Ukuzinza
3.Izinto ezivinjiwe: Ama-oxidants aqinile, ama-acids, izisekelo
4.Ingozi yePolymerisation: Ukungeyona i-polymerization
Isicelo somkhiqizo:
1.Lo mkhiqizo uyi-ejenti yokomisa kancane futhi esheshayo ye-flexographic kanye ne-gravure inki, ikakhulukazi ukuphrinta kumafilimu e-olefin ne-polyamide.Ibuye isetshenziswe njenge-solvent ye-nitrocellulose;Irabha ekloriniwe kanye namapulasitiki e-phenolic e-thermo-reactive.I-Propyl acetate inephunga elincane lezithelo.Uma ihlanjululwe, inephunga elifana nepheya.Imikhiqizo yemvelo ikhona kubhanana;utamatisi;amazambane ahlanganisiwe nokunye.Imithetho yaseChina ye-GB2760-86 yokusetshenziswa okuvunyelwe kwezinongo ezidliwayo.Ikakhulukazi isetshenziswa ekulungiseleleni i-pear kanye ne-currant nezinye izinhlobo zokunambitheka, futhi isetshenziswa njenge-solvent yamakha asekelwe esithelweni.Inani elikhulu lezinto eziphilayo kanye ne-inorganic ezisetshenziswa njenge-solvent yokukhipha, upende, upende we-nitro spray, i-varnish nama-resin ahlukahlukene kanye nezincibilikisi kanye nokukhiqizwa kwezinongo.
2.Isetshenziswa ekwenzeni izinongo ezidliwayo.Ibuye isetshenziswe njenge-nitrocellulose, irabha ekloriniwe kanye nevolumu yepulasitiki ye-phenolic esebenzayo ekushiseni, kanye nopende, ipulasitiki, i-organic synthesis.
I-3.Isetshenziswa njenge-agent yokunambitheka, izinongo ezidliwayo, i-nitrocellulose solvent kanye ne-reagent, kanye nokusetshenziswa ekwenzeni i-lacquer, amapulasitiki, i-organic synthesis nokunye.
Amanothi Okugcina Umkhiqizo:
1.Gcina endaweni epholile, nengena umoya.
2. Gcina kude nomlilo kanye nomthombo wokushisa.
3.Izinga lokushisa lokugcina akufanele lidlule37°C.
4.Gcina isitsha sivaliwe.
5.Kufanele igcinwe ngokuhlukana nama-oxidizing agents,ama-alkali nama-asidi,futhi akufanele neze ixutshwe.
6.Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.
7.Vimbela ukusetshenziswa kwemishini namathuluzi alula ukwenza izinhlansi.
8.Indawo yokugcina impahla kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto zokukhosela ezifanele.
