Ke hobane'ng ha lidae tse qhalakaneng li eketsa glacial acetic acid

Hobaneng ha lidae tse hasaneng li eketsa glacial acetic acid,
glacial acetic acid ea malapeng, Glacial Acetic Acid, Baetsi ba glacial acetic acid, Bafani ba Acetic Acid ea Glacial, Hebei glacial acetic acid,
Tlhaloso ea boleng(GB/T 1628-2008)

Lintho tsa Physicochemical:
1. Mokelikeli o se nang 'mala le dour e hlabang.
2. Ntho e qhibilihang 16.6 ℃; ntlha e belang 117.9 ℃; Ntlha ea Flash: 39 ℃.
3. Metsi a qhibilihang, ethanol, benzene le ethyl ether immiscible, a sa keneng ka har'a carbon disulphide.

Polokelo:
1. E bolokiloe ntlong ea polokelo e pholileng, e nang le moea o pholileng.
2. Boloka hole le mollo, mocheso. Sehla se batang se lokela ho boloka mocheso o fetang 16 ° C, ho thibela ho tiea. Nakong ea serame, mocheso o lokela ho bolokoa ka holimo ho 16 ° C ho thibela / ho qoba ho tiisa.
3. Boloka setshelo se tiisitsoe. E lokela ho aroloa ho tloha ho oxidant le alkali. Ho kopanya ho lokela ho qojoa ka mekhoa eohle.
4. Sebelisa mabone a thibelang ho phatloha, lisebelisoa tsa moea.
5. Lisebelisoa tsa mechine le lisebelisoa tse thibelang tšebeliso ea litlhase tse bonolo ho hlahisa.
6. Libaka tsa polokelo li lokela ho ba le thepa ea phekolo ea tšohanyetso le thepa e loketseng ea bolulo.

Sebelisa:

1.Derivative: Haholo-holo e sebelisoa ha ho etsoa acetic anhydride, acetic ether, PTA, VAC/PVA,CA, ethenone, chloroacetic acid, joalo-joalo.
2. Pharmaceutical:Acetic acid e le solvent le pharmaceuticalraw materials, haholo-holo e sebediswa bakeng sa tlhahiso ea penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, le sulfamethoxazole isoxazole, norfloxacin,ciprofloxalicy, acetinanisolic, acetinanisolic acid, prefloxacin, acetinanisolic, acetyl, sulfadiazine. , caffeine, joalo-joalo.
3.Intermediate: acetate, sodium hydrogen di, peracetic acid, joalo-joalo
4.Dyestuff le textile printing and dyeing: E ​​sebelisoa haholo ho hlahisa lidae tse qhalakaneng le lidae tsa vat, le khatiso ea masela le ts'ebetso ea ho daea
5. Synthesis ammonia: Ka sebōpeho sa cuprammonia acetate, e sebelisoang ho hloekisa li-syngas ho tlosa litl CO le CO2.
6. Senepe: Moqapi
7. Rabara ea tlhaho: Coagulant
8. Indasteri ea kaho: Ho thibela konkreite ho tloha frezing9. In addtin e boetse e sebelisoa haholo kalafong ea metsi, li-syntheticfiber, chefo e bolaeang likokoanyana, polasetiki, letlalo, pente, ts'ebetso ea tšepe le indasteri ea rabara.

Lidae tse qhalaneng li sebelisoa letsatsi le leng le le leng, empa u ka re hang-hang, ke hobane'ng ha li-dae tse qhalaneng li eketsa glacial acetic acid ho fetola PH? (Li-Organic acid joale li kentsoe ho lokisa PH, ntle le litšila tsa alkaline disperse.)

Lebaka ke:

Ho tsitsa ha lidae tse qhalaneng ka bateng ea dae ho amana haufi-ufi le boleng ba pH. Haholo-holo mocheso o phahameng le khatello e phahameng, haeba pH ea boleng ba ho hlatsoa dae e sa laoloe ka thata, hangata e tla baka ho fapana ha leseli la mebala, mabaka a ka sehloohong ke a latelang.

(1) Etsa hore ho potlakisoa ha hydrolysis ea lidae tse qhalakaneng, ha ho etsoa dae, hangata ho eketsa palo e kholo ea li-dispersant, joalo ka diffuser NNO, lignin, sodium carbonate, e le hore tharollo ea dae e fokotsehe alkaline.
Ha u daea ka mocheso o phahameng oa 130%, ho bonolo ho hydrolyze, ho fella ka 'mala o bobebe le khanya e fokolang.
(2) Ka lebaka la ho fokotseha ha ho senyeha ha lidae tse qhalakaneng, ho lahleheloa ke sehlopha sa moriri oa moriri, ketsahalo ena e atisa ho ba sebopeho sa azo sa dae.
(3) Sehlopha sa phenolic sebopeho sa limolek'hule tsa dae se baka maikutlo a ionic ka lebaka la ketso ea alkali, 'me ho qhibiliha ha metsi hoa ntlafatsoa, ​​ha ho daea holimo ho fokotsehile ka tsela e tšoanang. Hangata, mokelikeli o qhalakang oa lidae o fokola alkaline ka lebaka la ho eketsoa ha dispersant ka bateng ea ho daea.
