Ibicuruzwa:
1. Buhoro buhoro hydrolysed imbere y'amazi kugirango itange aside acike na propanol.Umuvuduko wa hydrolysis ni 1/4 cyurwego rwa Ethyl acetate.Iyo propyl acetate ishyutswe kugeza kuri 450 ~ 470 ℃, usibye kubyara protylene na acide acike, hariho acetaldehyde, propionaldehyde, methanol, Ethanol, Ethane, Ethylene namazi.Imbere ya catalizike ya nikel, yashyutswe kuri 375 ~ 425 ℃, ibisekuruza bya monoxyde de carbone, dioxyde de carbone, hydrogen, metani na Ethane.Chlorine, bromine, hydrogen bromide na propyl acetate bigira ubushyuhe buke.Iyo ikozwe na chlorine munsi yumucyo, 85% ya monochloropropyl acetate ikorwa mumasaha 2.Muri ibyo, 2/3 ni 2-chloro isimburwa na 1/3 ni 3-chloro.Imbere ya aluminium trichloride, protyl acetate ishyutswe na benzene kugirango ikore propylbenzene, 4-propylacetophenone na isopropylbenzene.
2. Guhagarara: Birahamye
3.Ibintu bibujijwe: Okiside ikomeye, acide, shingiro
4.Polymerisation hazard: Non-polymerisation
Gusaba ibicuruzwa:
1.Ibicuruzwa nigikoresho cyumye kandi cyihuta cyumuti wa flexographic na gravure wino, cyane cyane mugucapisha kuri firime ya olefin na polyamide.Ikoreshwa kandi nk'umuti wa nitrocellulose;reberi ya chlorine na plastike ya fenolike ya termo-reaction.Propyl acetate ifite impumuro nziza yimbuto.Iyo ivanze, iba ifite impumuro nziza.Ibicuruzwa bisanzwe bibaho mubitoki;inyanya;kuvanga ibirayi n'ibindi.Ubushinwa GB2760-86 amabwiriza yo gukoresha ibirungo biribwa byemewe.Ahanini ikoreshwa mugutegura amapera nimbuto nubundi bwoko bwa flavours, nayo ikoreshwa nkigishishwa cyimpumuro nziza yimbuto.Umubare munini wibintu kama nubuhinzi-mwimerere bikoreshwa nkumuti wo gukuramo, gusiga irangi, irangi rya nitro spray, langi hamwe nubutaka butandukanye hamwe numuti hamwe no gukora ibirungo.
2.Yakoreshejwe mugukora ibirungo biribwa.Ikoreshwa kandi nka nitrocellulose, reberi ya chlorine hamwe nubushyuhe bwa fenolike yubushyuhe, kimwe no gusiga irangi, plastike, synthesis.
3.Bikoreshwa nkibintu biryoha, ibirungo biribwa, nitrocellulose solvent na reagent, kimwe no gukoreshwa mugukora lacquer, plastike, synthesis organique nibindi.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Ubushyuhe bwo kubika ntibugomba kurenga37° C.
4.Komeza ikintu gifunze.
5.Bigomba kubikwa bitandukanye na okiside,alkalis na aside,kandi ntigomba na rimwe kuvangwa.
6. Koresha ibikoresho biturika biturika kandi bihumeka.
7.Kubuza gukoresha ibikoresho bya mashini nibikoresho byoroshye kubyara ibishashi.
8.Ahantu ho guhunika hagomba kuba harimo ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
