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 (inonziwo acetic acid, glacial acetic acid, kana fomula CH COOH) ndeye organic mono acid iyo ₃ ndiko kunobva acidity uye kunhuhwirira kunotyisa muvhiniga. Pure anhydrous acetic acid (glacial acetic acid) imvura isina ruvara ine hygroscopic ine kutonhora kwe16.7 ° C (62 ° F) uye inova kristaro isina ruvara pakuomarara. Kunyange zvazvo acetic acid iri asidhi isina simba inobva pakukwanisa kwayo kuparadzanisa mumhinduro dzine mvura, acetic acid inoparadza uye mhute yayo inogumbura maziso nemhino.
acetic acid, saturated carboxylic acid ine maatomu maviri ekabhoni, yakakosha-ine oxy inotorwa kubva kumahydrocarbon. Molecular formula C2H4O₂, chimiro Molecular chimiro
Molecular structure
Iyo pfupi CH₃COOH, HAC ndiyo fomu pfupi. Iro boka rinoshanda rechimiro chechimiro iboka recarboxyl uye nhamba yeCAS ndeye 64-19-7. Nekuti ndicho chikamu chikuru chevhiniga, inozivikanwawo seacetic acid. Mumichero kana mafuta emiriwo, somuenzaniso, kunyanya mumhando ye esters yemiti yavo; Iyo iripo seyemahara asidhi munyama, tsvina, uye ropa remhuka. Vhiniga yakajairika ine 3% kusvika 5% acetic acid. Acetic acid imvura isina ruvara uye ine kunhuhwirira kwakasimba. Huremu hwema molecular huremu ndeye 60.05, nzvimbo yekunyunguduka i16.6 ℃, iyo yekubikira i117.9 ℃, density iri 1.0492 (20/4 ℃), density yakakwira kupfuura iyo yemvura, iyo refractive index i1.3716. Pure acetic acid inogona kuumba ice-like solid pazasi 16.6 ° C, saka inowanzonzi glacial acetic acid. Soluble mumvura, ethanol, ether uye carbon tetrachloride. Kana mvura yawedzerwa kune acetic acid, huwandu hwese hunoita hudiki uye huwandu hunowedzera kusvika chiyero chemolecular chave 1: 1, inoenderana nekuumbwa kwemono-acid CH3C (OH) ₃, iyo inowedzera kuderedzwa uye isingachashanduki muhuwandu. .
