Iimpawu zePhysicochemical:
1. Ulwelo olungenambala kunye ne-dour ecaphukisayo.
2. Indawo yokunyibilika 16.6 ℃;indawo yokubilisa 117.9℃;Indawo edanyazayo: 39 ℃.
3. Amanzi anyibilikayo, i-ethanol, ibenzene kunye ne-ethyl ether immiscible, enganyibilikiyo kwicarbon disulphide.
Ugcino:
1. Igcinwe kwindawo epholileyo, nengena umoya.
2. Gcina kude nomlilo, shushu.Ixesha elibandayo kufuneka ligcine ubushushu obungaphezulu kwe-16 DEG C, ukuthintela ukuqina.Ngexesha elibandayo, ubushushu kufuneka bugcinwe ngaphezu kwe-16 DEG C ukunqanda/ukuphepha ukuqina.
3. Gcina isitya sivaliwe.Kufuneka yahlulwe kwi-oxidant kunye ne-alkali.Ukuxuba kufuneka kuphetshwe ngazo zonke iindlela.
4. Sebenzisa izibane ezingagqabhukiyo, izixhobo zokungenisa umoya.
5. Izixhobo zoomatshini kunye nezixhobo ezivimbela ukusetyenziswa kwezinto ezilula ukuvelisa iintlantsi.
6. Iindawo zokugcina kufuneka zixhotyiswe ngezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zezindlu.
Sebenzisa:
1.I-Derivative: Isetyenziswa kakhulu ekwenzeni i-acetic anhydride, i-acetic ether, i-PTA, i-VAC/PVA, i-CA, i-ethanone, i-chloroacetic acid, njl.
2.Pharmaceutical:Acetic acid as solvent and pharmaceuticalraw materials, ikakhulu esetyenziselwa imveliso penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, kunye sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetinelic acid, acetyl, preacetyl ,icaffeine, njl.
3.Ephakathi:iacetate,sodium hydrogen di,peracetic acid, njl
4. Idayi kunye noshicilelo olulukiweyo kunye nokudaya: Isetyenziswa kakhulu ukuvelisa iidayi ezisasazwayo kunye nedayi yevat, kunye nokuprintwa kwelaphu kunye nokudaywa
5. I-Synthesis ammonia: Ikwimo ye cuprammonia acetate, esetyenziswa ekusulungekiseni i-syngas ukususa i-litl CO kunye ne-CO2
6. Ifoto: uMphuhlisi
7. Irabha yendalo: I-Coagulant
8. Ushishino lokwakha: Ukuthintela ikhonkrithi ekukhenkceni9.Kwi-addtin ikwasetyenziswa ngokubanzi kunyango lwamanzi, i-syntheticfiber, i-pesticides, iiplastiki, ufele, ipeyinti, ukusetyenzwa kwesinyithi kunye neshishini lerubha.
Ukusabalalisa idayi zisetyenziswa yonke imihla, kodwa unokuthi ngokukhawuleza, kutheni ukusasaza idayi nge-acetic acid ye-glacial ukulungelelanisa i-PH?(Iiasidi ze-Organic zongezwa ngoku ukulungisa i-PH, ngaphandle kwe-alkaline disperse dyeing)
Isizathu kukuba:
Ukuzinza kweedayi ezisasazwayo kwibhafu yokudaya kunxulumene ngokusondeleyo nexabiso le-pH.Ngokukodwa kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu, ukuba ixabiso le-pH lokuhlamba idayi alilawulwa ngokungqongqo, liza kubangela ukuhluka kokukhanya kombala, izizathu eziphambili zilandelayo.
(1) Ibangela i-hydrolysis ekhawulezileyo yeedayi ezisasaza, kwinkqubo yokwenziwa kwedayi, zihlala zongeza inani elikhulu lezinto ezisasazwayo ezifana ne-arhente yokusasaza i-NNO, i-lignin, i-sodium carbonate, njl., ukuze idayi ibuthathaka ialkaline,
Xa udayi nge-130% yobushushu obuphezulu, kulula ukwenza i-hydrolyze, okukhokelela kumbala okhanyayo kunye nombala otyhafileyo.
(2) Ngenxa yokunciphisa ukubola kwedayi ezisasazwayo, ukulahleka kweqela le-chromophore, le nto idla ngokuphindaphindiweyo kwiidayi ezine-azo structure.
(3) Iqela le-phenolic kwisakhiwo se-molecular yedayi ibangela ukusabela kwe-ionic ngenxa yesenzo se-alkali, ukunyibilika kwamanzi kuphuculwe, kwaye ukudaya kubuthathaka ngokufanelekileyo, ngokufuthi ngenxa yokongezwa kwe-disperant kwibhafu yokudaya. , okubangela ukusasazwa kwedayi nge-alkaline ebuthathaka.
