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.
Acetic acid, inozivikanwawo seacetic acid (36% -38%), glacial acetic acid (98%), kemikari formula CH3COOH, ndeye organic monic acid, chikamu chikuru chevhiniga. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid ine kutonhora kwe16.6 ° C (62 ° F) uye inova kristaro isina ruvara mushure mekuoma. Mushonga wayo une aqueous hauna kusimba asidhi uye inoparadza, uye chiutsi chinogumbura maziso nemhino.
Glacial acetic acid (pure matter), kureva anhydrous acetic acid, organic compound. Inoomesa muchando pakudziya kwakaderera uye inowanzozivikanwa se glacial acetic acid. Kuwedzera kwevhoriyamu panguva yekusimba kunogona kuita kuti mudziyo uputika. Iyo flash point ndeye 39 ℃, iyo inoputika muganho ndeye 4.0% ~ 16.0%, uye iyo yakanyanya kubvumidzwa yekuisa mumhepo haipfuure 25mg/m3. Pure acetic acid inoomesa kuita ice-sekristaro pazasi peinonyungudika, saka anhydrous acetic acid inonziwo glacial acetic acid.
Zvinogona kuonekwa kuti izvo zviviri hazvina kufanana, iyo flash point ye ice acetic acid ndeye 39 ℃, iyo inoputika muganho ndeye 4.0% ~ 16.0%, uye iyo yakanyanya kubvumidzwa kusungwa mumhepo haipfuure 25mg/m3, inova. kune zvinhu zvine ngozi, uye acetic acid haisi zvinhu zvine ngozi.
