Physicochemical properties:
1. Mvura isina ruvara uye dour inogumbura.
2. Kunyungudika 16.6 ℃; kuvira poindi 117.9 ℃; Flash point: 39 ℃.
3. Mvura inonyungudika, ethanol, benzene uye ethyl ether immiscible, isinganyunguriki mucarbon disulphide.
Kuchengeta:
1. Kuchengeterwa muimba inotonhorera inofefetera.
2. Ramba kure nemoto, kupisa. Mwaka unotonhora unofanirwa kuchengetedza tembiricha yakakwira kupfuura 16 DEG C, kudzivirira kusimba. Munguva yekutonhora, tembiricha inofanirwa kuchengetedzwa pamusoro pe16 DEG C kudzivirira / kudzivirira kusimba.
3. Chengeta mudziyo wakavharwa. Inofanirwa kuparadzaniswa kubva kune oxidant uye alkali. Kusanganiswa kunofanira kudziviswa nenzira dzose.
4. Shandisa kuputika-kuvhenekera kwechiedza, zvivako zvemhepo.
5. Mechanical midziyo uye maturusi anorambidza kushandiswa nyore kubudisa sparks.
6. Nzvimbo dzekuchengetera dzinofanira kunge dzakashongedzerwa nemichina yekurapa kwekukurumidzira uye zvinhu zvakakodzera zvemba.
Shandisa:
1.Derivative:Inonyanya kushandiswa mukugadzira acetic anhydride,acetic ether,PTA,VAC/PVA,CA,ethenone,chloroacetic acid,etc.
2. Pharmaceutical:Acetic acid se solvent uye pharmaceuticalraw materials, inonyanya kushandiswa kugadzirwa kwepenicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, uye sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetinalic acid, acetinalic acid, prefloxacin, acetinalic acid , caffeine, nezvimwewo.
3.Ipakati:acetate,sodium hydrogen di,peracetic acid,etc
4.Dyestuff uye machira kudhinda uye dhayi: Inonyanya kushandiswa kugadzira dhayi anoparadzira uye dhayi yevat, uye kudhinda machira uye kugadzira dhayi.
5. Synthesis ammonia: Muchimiro che cuprammonia acetate, inoshandiswa mukunatsa syngas kubvisa litl CO uye CO2.
6. Mufananidzo: Mugadziri
7. Natural rubber: Coagulant
8. Indasitiri yekuvaka: Kudzivirira kongiri kubva kune frezing9. In addtin zvakare inoshandiswa zvakanyanya mukurapa kwemvura, syntheticfiber, mishonga yezvipembenene, mapurasitiki, dehwe, pendi, simbi yekugadzirisa uye indasitiri yerubha.
Glacial acetic acid (pure matter), kureva, anhydrous acetic acid, acetic acid ndeimwe yeakakosha organic acids, organic compounds. Inoomesa muchando pakupisa kwakadzika, inowanzozivikanwa se glacial acetic acid. Kuwedzera kwevhoriyamu panguva yekusimba kunogona kuita kuti mudziyo utyoke. Flash point 39 ℃, kuputika muganho 4.0% ~ 16.0%, iyo yakanyanya kubvumidzwa yekuisa mumhepo haisi kupfuura 25mg/m3. Pure acetic acid inoomesa muchando mumakristasi pazasi peinonyungudika, saka anhydrous acetic acid inonziwo glacial acetic acid.
use
Kushandisa: Inonyanya kushandiswa kugadzira vinyl acetate, acetate fiber, acetic anhydride, acetate, metal acetate uye halogenated acetic acid. Iyo yakakoshawo mbishi zvinhu zvemishonga, dhayi, mushonga wezvipembenene uye mamwe organic synthesis. Pamusoro pezvo, inoshandiswa zvakanyanya mukugadzira mishonga yemifananidzo, cellulose acetate, kudhinda machira uye dhayi uye maindasitiri erabha, zvinonyungudutsa zvekugadzira mapurasitiki, dhayi, kutora mafoto, mushonga, mishonga yezvipembenene uye zvimwe zvigadzirwa zveorganic synthesis.
