Iinkcazelo Ngeempawu zeMveliso:
1.Efana ne-butyl acetate.Ibola kwi-1-butene, 2-butene, ethylene kunye nepropylene xa ishushu kwi-500 °C.Xa i-sec-butyl acetate igqithiswa ngoboya beglasi kumlambo wenitrogen ku-460 ukuya kuma-473 ° C, 56% 1-butene, 43% 2-butene kunye ne-1% yepropylene iveliswa.Xa ishushu kwi-380 ° C phambi kwe-thorium oxide, iyancipha ibe yi-hydrogen, i-carbon dioxide, i-butene, i-sec-butanol kunye ne-acetone.Izinga le-hydrolysis ye-sec-butyl acetate lincinci.Xa i-ammonolysis ivela kwisisombululo esinxilisayo esixutywe kwiqondo lokushisa, i-20% iguqulwa ibe yi-amide kwiiyure ze-120.Idibana ne-benzene xa kukho i-boron trifluoride ukwenza i-sec-butylbenzene.Xa i-photo-chlorination iqhutyelwa, i-chlorobutyl acetate yenziwa.Phakathi kwabo, i-1-methyl-2 i-chloropropyl acetate i-akhawunti ye-66% kunye nezinye i-isomers i-akhawunti ye-34%.
2.Uzinzo: Izinzile
3.Izinto ezingavumelekanga:Unamandla oxiiidanti, iiasidi ezinamandla, iziseko ezomeleleyo
4.Ingozi yePolymerization:Non-pi-olymerization
Isicelo seMveliso:
I-1.Isetyenziswa kakhulu kwi-lacquer solvents, i-thinners, i-oyile eyahlukeneyo yemifuno kunye ne-resin solvents.Ikwasetyenziswa kwiplastiki nakwimveliso yeziqholo.I-agent echasene nepetroli.
I-2.Isetyenziswe njenge-solvents, i-reagents yeekhemikhali, ezisetyenziselwa ukulungiswa kweziqholo
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-oxidising 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.
