Iimpawu zeMveliso:
1.Kancinci i-hydrolysed phambi kwamanzi ukuvelisa i-acetic acid kunye nepropanol. Isantya se-hydrolysis yi-1/4 ye-ethyl acetate.Xa i-propyl acetate ishushu kwi-450 ~ 470 ℃, ngaphezu kokuvelisa i-propylene kunye ne-acetic acid, kukho i-acetaldehyde, i-propionaldehyde, i-methanol, i-ethanol, i-ethane, i-ethylene kunye namanzi. Phambi kwe-nickel catalyst, ishushu kwi-375 ~ 425 ℃, ukuveliswa kwe-carbon monoxide, i-carbon dioxide, i-hydrogen, i-methane kunye ne-ethane. I-chlorine, i-bromine, i-hydrogen bromide kunye ne-propyl acetate zisabela kumaqondo obushushu aphantsi. Xa kuphendulwa nge-chlorine phantsi kokukhanya, i-85% ye-monochloropropyl acetate iveliswa kwiiyure ze-2. Koku, i-2/3 yi-2-chloro substituent kunye ne-1/3 yi-3-chloro substituent. Xa kukho i-aluminiyam trichloride, ipropyl acetate ifudunyezwa ngebenzene ukwenza ipropylbenzene, 4-propylacetophenone kunye ne-isopropylbenzene.
2.Uzinzo: Izinzile
3.Izinto ezivinjelwayo: I-oxidants enamandla, i-acids, iziseko
4.Ingozi yokwenziwa kwePolymerisation: Ukungasetyenziswa kwepolymerisation
Isicelo seMveliso:
I-1.Le mveliso yi-ejenti eyomileyo ecothayo kwaye ekhawulezayo yee-inks ze-flexographic kunye ne-gravure, ngakumbi ukuprintwa kwiifilimu ze-olefin kunye ne-polyamide. Ikwasetyenziswa njengesinyibilikisi senitrocellulose; irabha ekloriniweyo kunye neeplastiki zephenolic ze-thermo-reactive. Ipropyl acetate inevumba elimnandi elineziqhamo. Xa ixutywe, inevumba elifana nepere. Iimveliso zendalo zikhona kwiibhanana; iitumato; iitapile ezihlanganisiweyo njalo njalo. Imithetho yaseTshayina ye-GB2760-86 yokusetyenziswa okuvunyelweyo kweziqholo ezidliwayo. Ikakhulu isetyenziswa ekulungiseleleni ipeyari kunye necurrant kunye nezinye iintlobo zeencasa, nazo zisetyenziselwa ukunyibilikisa iziqholo ezisekelwe kwiziqhamo. Inani elikhulu lezinto eziphilayo kunye nezinto ezingaphiliyo ezisetyenziselwa ukunyibilikisa ukutsalwa, ipeyinti, ipeyinti ye-nitro yokutshiza, ivanishi kunye neerasi ezahlukeneyo kunye nezinyibilikisi kunye nokwenziwa kweziqholo.
2.Isetyenziswa ekwenzeni iziqholo ezityiwayo. Ikwasetyenziswa njenge nitrocellulose, irabha ekloriniweyo kunye nobushushu obusebenzayo phenolic umthamo weplastiki, kunye nepeyinti, iplastiki, i-organic synthesis.
I-3.Isetyenziswe njenge-agent ye-flavoring, i-spice edliwayo, i-nitrocellulose i-solvent kunye ne-reagent, kunye nokusetyenziswa ekwenzeni i-lacquer, iiplastiki, i-organic synthesis kunye nokunye.
Amanqaku okuGcina iMveliso:
1.Gcina kwindawo epholileyo nengena umoya.
2. Gcina kude nomlilo kunye nomthombo wobushushu.
3.Ubushushu bokugcina akufanele budlule37°C.
4. Gcina isitya sivaliwe.
5. Kufuneka igcinwe ngokwahlukileyo kwi-oxidizing agents,i-alkalis kunye neeasidi,kwaye mayingaze ixutywe.
6.Sebenzisa izibane ezingagqabhukiyo kunye nezixhobo zokungenisa umoya.
7.Vimbela ukusetyenziswa kwezixhobo zoomatshini kunye nezixhobo ekulula ukuvelisa iintlantsi.
8.Indawo yokugcina kufuneka ixhotyiswe ngokuvuza kwezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zokukhusela.
