Katundu:
1.Pang'onopang'ono hydrolysed pamaso pa madzi kupanga acetic acid ndi propanol.Liwiro la hydrolysis ndi 1/4 la ethyl acetate.Pamene propyl acetate yatenthedwa kufika 450 ~ 470 ℃, kuwonjezera pa kupanga propylene ndi acetic acid, pali acetaldehyde, propionaldehyde, methanol, ethanol, ethane, ethylene ndi madzi.Pamaso pa nickel chothandizira, kutentha kwa 375 ~ 425 ℃, m'badwo wa carbon monoxide, carbon dioxide, haidrojeni, methane ndi ethane.Chlorine, bromine, hydrogen bromide ndi propyl acetate amachita pa kutentha kochepa.85% ya monochloropropyl acetate ikachitidwa ndi chlorine pansi pa kuwala, imapangidwa mkati mwa maola awiri.Mwa izi, 2/3 ndi 2-chloro m'malo ndipo 1/3 ndi 3-chloro m'malo.Pamaso pa aluminium trichloride, propyl acetate imatenthedwa ndi benzene kupanga propylbenzene, 4-propylacetophenone ndi isopropylbenzene.
2.Kukhazikika: Kukhazikika
3.Zinthu zoletsedwa: Ma oxidants amphamvu, ma acid, maziko
4.Polymerization ngozi: Kupanda polymerization
Ntchito Yogulitsa:
1.Chida ichi ndi chowumitsa pang'onopang'ono komanso chofulumira cha inki za flexographic ndi gravure, makamaka kusindikiza pa mafilimu olefin ndi polyamide.Amagwiritsidwanso ntchito ngati zosungunulira za nitrocellulose;mphira wa chlorinated ndi thermo-reactive phenolic mapulasitiki.Propyl acetate ili ndi fungo la zipatso pang'ono.Akathiridwa, amakhala ndi fungo la peyala.Zinthu zachilengedwe zimapezeka mu nthochi;tomato;mbatata zosakaniza ndi zina zotero.Malamulo aku China a GB2760-86 ogwiritsira ntchito zokometsera zololedwa.Amagwiritsidwa ntchito pokonza peyala ndi currant ndi mitundu ina ya zokometsera, zomwe zimagwiritsidwanso ntchito ngati zosungunulira za zonunkhira za zipatso.Zinthu zambiri za organic ndi inorganic zomwe zimagwiritsidwa ntchito ngati zosungunulira, utoto, utoto wa nitro spray, varnish ndi ma resins osiyanasiyana ndi zosungunulira komanso kupanga zonunkhira.
2.Kugwiritsidwa ntchito popanga zokometsera zodyedwa.Amagwiritsidwanso ntchito ngati nitrocellulose, mphira wothira mafuta ndi kutentha zotakataka phenolic pulasitiki voliyumu, komanso utoto, pulasitiki, organic synthesis.
3.Kugwiritsidwa ntchito ngati zokometsera, zokometsera zodyera, zosungunulira za nitrocellulose ndi reagent, komanso zimagwiritsidwa ntchito popanga lacquer, mapulasitiki, organic synthesis ndi zina zotero.
Zolemba Zosungira:
1.Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi moto ndi gwero la kutentha.
3.Kutentha kosungirako sikuyenera kupitirira37°C.
4.Sungani chidebe chosindikizidwa.
5. Iyenera kusungidwa mosiyana ndi oxidizing agents,alkali ndi zidulo,ndipo zisasokonezedwe.
6.Gwiritsani ntchito zounikira zosaphulika ndi mpweya wabwino.
7.Letsani kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kupanga zopsereza.
8.Malo osungiramo zinthu ayenera kukhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zogona.
