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.
Glacial acetic acid (xaalad saafi ah), taas oo ah, anhydrous acetic acid, acetic acid waa mid ka mid ah acids organic muhiim ah, xeryahooda organic. Waxay ku adkaysataa baraf heerkul hooseeya, oo loo yaqaan 'glacial acetic acid'. Ballaarinta mugga inta lagu jiro adkaynta waxay keeni kartaa weelka inuu jabo. Flash point 39 ℃, xadka qaraxa 4.0% ~ 16.0%, xooga la ogolyahay ugu badnaan ee hawadu kama badna 25mg/m3. Ashitada saafiga ah ee acetic acid waxay ku barafoobi doontaa kiristaalo barafka ka hooseeya barta dhalaalka, sidaa darteed anhydrous acid waxaa sidoo kale loo yaqaannaa glacial acetic acid.
isticmaal
Codsiga: Inta badan waxaa loo isticmaalaa isku-dhafka vinyl acetate, fiber acetate, acetic anhydride, acetate, acetate birta iyo acetic acid halogenated. Sidoo kale waa walxo ceeriin ah oo muhiim u ah dawooyinka, dheeha, sunta cayayaanka iyo kuwa kale ee dabiiciga ah. Intaa waxaa dheer, waxaa sidoo kale si ballaaran loo isticmaalaa in wax soo saarka ee daroogada sawiro, acetate cellulose, daabacaadda dharka iyo rinjiyeynta iyo warshadaha caaga ah, dareere ah ee wax soo saarka ee caagadaha, dheeha, sawir qaadis, daawo, sunta cayayaanka iyo alaabta kale ee cayriin ee synthesis organic.
