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 waxaa caadi ahaan loo yaqaan acetic acid. Xalka glacial acetic acid waxaa loo isticmaali karaa daaweynta kiliinikada ee noocyo kala duwan oo caabuq fangas maqaarka ah, xitaa caabuq fangas ciddiyaha iyo wixii la mid ah. Marka glacial acetic acid loo isticmaalo in lagu daweeyo caabuqyada fangas, 30% xal glacial acetic acid ayaa sida caadiga ah loo isticmaalaa. Waxaa loo isticmaalaa in lagu daweeyo cidiyaha cawl. Waxaa la isticmaali karaa ka dib marka la nadiifiyo ciddiyaha jiran iyo khafiifinta ciddiyaha. Maqaarka ku xiga ciddiyaha waxaa lagu ilaalin karaa lakabka jelly batroolka. Marka la daaweynayo galleyda iyo burooyinka maqaarka, waa inaad sidoo kale nadiifisaa meelaha buka ka hor intaadan dawada qaadan, ku qool biyo kulul, ka dibna mari dawada. Ogsoonow in glacial acetic acid ay leedahay saameyn daxaleed gaar ah, sidaas darteed waxaa fiican inaadan u isticmaalin caabuqyada fangas ee wejiga. Marka la isticmaalayo, waxaa muhiim ah in la ogaado in ka sokow aagga jirran, qaybaha kale ee maqaarka ayaa ugu fiican in la marsado Vaseline si loo ilaaliyo.
