Astaamaha physicochemical:
1. Dareere aan midab lahayn iyo dhadhan cuncun leh.
2. Barta dhalaalka 16.6 ℃; barta karkarinta 117.9 ℃; Dhibicda birta ah: 39 ℃.
3. Biyaha milmi kara, ethanol, benzene iyo ethyl ether immiscible, oo aan milmin karin disulfide carbon.
Kaydinta:
1. Waxaa lagu kaydiyaa bakhaar qabow oo hawo leh.
2. Ka ilaali dabka, kulaylka. Xilliga qabowgu waa inuu ilaaliyaa heerkul ka sarreeya 16 DEG C, si looga hortago adkaanta. Inta lagu jiro xilliga qaboobaha, heerkulka waa in lagu hayaa ka sarreeya 16 DEG C si looga hortago / looga fogaado adkaanta.
3. Weelka ha xidho. Waa in laga soocaa oxidant iyo alkali. Isku darka waa in laga fogaado si walba.
4. Isticmaal nalalka aan qarxin, tas-hiilaadka hawo-qaadista.
5. Qalabka makaanikada iyo qalabka mamnuucaya isticmaalka fudud ee soo saarista dhimbiil.
6. Goobaha kaydinta waa in lagu qalabeeyaa qalabka daaweynta degdega ah iyo qalab guri oo ku habboon.
Isticmaal:
1.Drivative: Inta badan loo isticmaalo synthetising acetic anhydride, acetic ether, PTA, VAC / PVA, CA, ethenone, chloroacetic acid, iwm
2.Pharmaceutical:Acetic acid sida dareeraha iyo alaabta farmashiyaha, inta badan loo isticmaalo soo saarista penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, iyo sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetyl acid, ,caffeine, iwm.
3. Dhexdhexaad: acetate, sodium hydrogen di, peracetic acid, iwm
4.Dyestuff and textile printing and coloring:Inta badan loo isticmaalo soo saarida dheeha kala firdhisan iyo midabada,iyo daabacaadda dunta iyo dheeynta
5. Synthesis ammonia: Qaabka loo yaqaan 'Cuprammonia acetate', oo loo isticmaalo sifaynta syngas si looga saaro litl CO iyo CO2
6. Sawir: Horumariye
7. Caag dabiici ah: Coagulant
8. Warshadaha dhismaha: Ka hortagga shubka ee qaboojinta9. In addtin sidoo kale si ballaaran loo isticmaalo daaweynta biyaha, syntheticfiber, sunta cayayaanka, balaastikada, maqaar, rinji, biraha warshadaynta iyo caagag.
Marka hore, dabeecaddu way ka duwan tahay
1, ice acetic acid: waa anhydrous acetic acid, acetic acid waa mid ka mid ah acids organic muhiimka ah, xeryahooda organic.
2, acetic acid: waa monic acid organic, qaybta ugu muhiimsan ee khalka.
Marka labaad, sifooyinka kala duwan
1, glacial acetic acid: waxay ku adkaysataa barafka heerkulka hooseeya, oo loo yaqaan glacial acetic acid. Ballaarinta mugga inta lagu jiro adkeynta waxay keeni kartaa weelka inuu dillaaco. Barta tooshku waa 39 ℃, xadka qaraxa waa 4.0% ~ 16.0%, iyo fiirsashada ugu badan ee la ogolyahay ee hawadu kama badna 25mg/m3. Ashitada saafiga ah ee acetic acid waxay ku barafoobi doontaa kiristaalo u eg barafka oo ka hooseeya barta dhalaalka, sidaas darteed anhydrous acid waxaa sidoo kale loo yaqaannaa glacial acetic acid.
2, acetic acid: waxa ku jira 98% glacial acetic acid, cufnaanta qaraabo (biyuhu waa 1): 1.050; Viscosity (mPa.s): 1.22 (20 ℃); Cadaadiska uumiga ee 20℃ (KPa): 1.5; Muuqashada iyo ur: dareere aan midab lahayn oo leh ur aashito ah.
Saddex, isticmaal kala duwan
1, glacial acetic acid: inta badan loo isticmaalo synthesis of vinyl acetate, acetate fiber, acetic anhydride, acetate, acetate biraha iyo halogenated acetic acid. Sidoo kale waa walxo ceeriin ah oo muhiim u ah dawooyinka, dheeha, sunta cayayaanka iyo kuwa kale ee dabiiciga ah.
2, acetic acid: waxaa loo isticmaali karaa sida nidaamiyaha aysiidhka, acidifier, wakiilka pickling, wakiilka dhadhanka, xawaash, iwm.
