Khoom Properties:
1.Muaj hydrolysed nyob rau hauv lub xub ntiag ntawm dej los tsim acetic acid thiab propanol. Lub hydrolysis ceev yog 1/4 ntawm ethyl acetate.Thaum propyl acetate yog rhuab mus rau 450 ~ 470 ℃, ntxiv rau tsim propylene thiab acetic acid, muaj acetaldehyde, propionaldehyde, methanol, ethanol, ethane, ethylene thiab dej. Nyob rau hauv lub xub ntiag ntawm nickel catalyst, rhuab mus rau 375 ~ 425 ℃, tiam ntawm carbon monoxide, carbon dioxide, hydrogen, methane thiab ethane. Chlorine, bromine, hydrogen bromide thiab propyl acetate hnov mob ntawm qhov kub thiab txias. Thaum reacted nrog chlorine nyob rau hauv lub teeb, 85% ntawm monochloropropyl acetate yog tsim nyob rau hauv 2 teev. Ntawm no, 2/3 yog 2-chloro hloov pauv thiab 1/3 yog 3-chloro hloov pauv. Nyob rau hauv lub xub ntiag ntawm txhuas trichloride, propyl acetate yog rhuab nrog benzene los tsim propylbenzene, 4-propylacetophenone thiab isopropylbenzene.
2.Stability: ruaj khov
3. Cov tshuaj txwv tsis pub: muaj zog oxidants, acids, bases
4.Polymerisation txaus ntshai: Tsis yog-polymerisation
Khoom siv:
1.Cov khoom no yog ib tug qeeb thiab ceev kom qhuav tus neeg sawv cev rau flexographic thiab gravure inks, tshwj xeeb tshaj yog rau luam tawm ntawm olefin thiab polyamide films. Nws kuj yog siv los ua ib qho hnyav rau nitrocellulose; chlorinated roj hmab thiab thermo-reactive phenolic plastics. Propyl acetate muaj me ntsis fruity aroma. Thaum diluted, nws muaj ib tug zoo li pear aroma. Cov khoom ntuj muaj nyob hauv txiv tsawb; txiv lws suav; compound qos yaj ywm thiab lwm yam. Tuam Tshoj tus GB2760-86 cov kev cai rau kev tso cai siv cov txuj lom edible. Feem ntau siv rau hauv kev npaj ntawm pear thiab currant thiab lwm yam flavours, kuj siv los ua ib qho hnyav rau cov txiv hmab txiv ntoo raws li fragrances. Ib tug loj tus naj npawb ntawm cov organic thiab inorganic tshuaj siv raws li ib tug hnyav rau extraction, xim, nitro spray xim, kua roj vanish thiab ntau yam resins thiab cov kuab tshuaj thiab tsim cov txuj lom.
2.Siv nyob rau hauv lub chaw tsim khoom ntawm edible txuj lom. Kuj tseem siv los ua nitrocellulose, chlorinated roj hmab thiab kub reactive phenolic yas ntim, nrog rau cov xim, yas, organic synthesis.
3.Siv raws li tus neeg sawv cev flavoring, edible spice, nitrocellulose hnyav thiab reagent, raws li zoo raws li siv nyob rau hauv lub tsim ntawm lacquer, plastics, organic synthesis thiab thiaj li nyob.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
3.Qhov kub cia yuav tsum tsis txhob tshaj37°C.
4. Khaws lub thawv kaw.
5.Nws yuav tsum tau muab cais los ntawm cov neeg ua haujlwm oxidizing,alkalis thiab acids,thiab yuav tsum tsis txhob sib xyaw.
6.Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab cov chaw ua pa.
7. Txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov pob zeb.
8.Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
