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.
Kuparadzira madhayi anoshandiswa mazuva ese, asi iwe unogona kubva wati, sei uchiparadzira dhayi dhayi ne glacial acetic acid kugadzirisa iyo PH? (Organic acids ikozvino yawedzerwa kugadzirisa PH, kunze kweiyo alkaline disperse dyeing)
Chikonzero ndechekuti:
Iko kugadzikana kwekuparadzira dhayi mudhayi yekugezesa kune hukama nepH kukosha. Kunyanya pakupisa kwepamusoro uye kudzvinyirira kukuru, kana pH kukosha kwedhayi yekugezera isinganyatsodzorwi, inowanzokonzera kusiyana kwechiedza chemavara, zvikonzero zvikuru ndezvizvi.
(1) Kukonzeresa kumhanyisa hydrolysis yekuparadzira dhayi, mukugadzira dhayi, kazhinji inowedzera huwandu hukuru hwekuparadzira senge diffusion agent NNO, lignin, sodium carbonate, nezvimwewo, kuitira kuti dhayi ive isina simba alkaline, mu
Kana uchidhaya pa 130% tembiricha yepamusoro, zviri nyore kuita hydrolyze, zvichikonzera ruvara rwakajeka uye kupera simba.
(2) Nekuda kwekuderera kwekuparara kwedhayi dzakapararira, kurasikirwa kweboka rechromophore, chiitiko ichi chinowanzo mudhayi ane azo chimiro.
(3) Iro phenolic boka mune molecular chimiro chedhayi inokonzera ionic reaction nekuda kwekuita kwealkali, kunyunguduka kwemvura kunowedzerwa, uye kudhaya kunopera simba maererano, kazhinji nekuda kwekuwedzera kweanoparadzira mubhati rekudhaya. , zvichikonzera kupararira kwedhayi ine alkaline isina simba.
