Izici Zomkhiqizo:
I-1.I-Ethyl acetate i-hydrolysed kalula, futhi kancane kancane i-hydrolysed ukwenza i-acetic acid ne-ethanol phambi kwamanzi ekamelweni lokushisa.Ukwengezwa kwamanani omkhondo we-asidi noma isisekelo kungakhuthaza ukusabela kwe-hydrolysis.I-Ethyl acetate nayo ingathola i-alcoalysis, i-ammonolysis, ukushintshaniswa kwe-ester, ukunciphisa nokunye ukusabela okuvamile kwama-ester avamile.Ifinyela ngokwayo phambi kwensimbi ye-sodium ukuze yakhe i-3-hydroxy-2-butanone noma i-ethyl acetoacetate;ihlangana ne-reagent ye-Grignard yakhe i-ketone, futhi ukusabela okuqhubekayo kunikeza utshwala obuphakeme.I-Ethyl acetate izinzile ekushiseni futhi ihlala ingashintshile lapho ishiselwa ku-290 ° C amahora angu-8-10.Ibola ibe i-ethylene ne-acetic acid lapho idlula epayipini lensimbi elibomvu elishisayo, ibe yi-hydrogen, i-carbon monoxide, i-carbon dioxide, i-acetone ne-ethylene nge-zinc powder eshiselwe ku-300 ~ 350 ° C, futhi emanzini, ethylene, carbon dioxide ne-acetone i-aluminium oxide ephelelwe amanzi ku-360°C.I-Ethyl acetate iboliswa imisebe ye-ultraviolet ukuze ikhiqize amaphesenti angu-55 e-carbon monoxide, amaphesenti angu-14 e-carbon dioxide namaphesenti angu-31 e-hydrogen noma i-methane, okungamagesi avuthayo.Ukusabela nge-ozone kukhiqiza i-acetaldehyde ne-acetic acid.I-gaseous hydrogen halide isabela ne-ethyl acetate yakhe i-ethyl halide ne-acetic acid.I-iodide ye-hydrogen iyona esebenza kakhulu, kuyilapho i-hydrogen chloride idinga ukucindezela ukuze ibole ekamelweni lokushisa, futhi ifudunyezwa ibe ngu-150°C nge-phosphorus pentachloride ukuze yakhe i-chloroethane ne-acetyl chloride.I-Ethyl acetate yakha ama-crystalline complexes ahlukahlukene anosawoti wensimbi.Lezi zinkimbinkimbi zincibilika ku-ethanol enamanzi kodwa hhayi ku-ethyl acetate futhi zifakwa kalula emanzini.
2.Ukuzinza: Ukuzinza
3.Izinto ezivinjiwe: Ama-oxidants aqinile, ama-alkali, ama-acids
4.Ingozi yePolymerisation: Ukungeyona i-polymerization
Isicelo somkhiqizo:
Ingasetshenziselwa ukuncibilikisa i-nitrocellulose, inki yokunyathelisa, uwoyela namafutha, njll. Ingasetshenziswa futhi njengempahla eluhlaza yamapende, isikhumba sokwenziwa, imikhiqizo yepulasitiki, udayi, imithi nezinongo, njll.
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-asidi nama-alkali,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.
