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.

Xoogga warshadda-5Midabyada kala firdhisan ayaa la isticmaalaa maalin kasta, laakiin waxaad isla markiiba odhan kartaa, maxay sababta midabada kala firdhiyaan ay ugu daraan glacial acetic acid si loo hagaajiyo PH? (Asiidhyada Organic ayaa hadda lagu daray si loo hagaajiyo PH, marka laga reebo wasakhaynta kala firdhisa alkaline.)

Sababtu waa:

Xasiloonida midabada kala firdhisan ee qubeyska dheeha ayaa si dhow ula xidhiidha qiimaha pH. Gaar ahaan heerkulka sare iyo cadaadiska sare, haddii qiimaha pH ee qubeyska dheeha aan si adag loo koontaroolin, waxay badanaa keeni doontaa kala duwanaanta iftiinka midabka, sababaha ugu muhiimsan waa sida soo socota.

(1) Sababta hydrolysis dardargelinta ee dheeh kala firdhiso, in habka wax soo saarka dheeha, inta badan ku dar tiro badan oo kala firdhiyey, sida diffuser NNO, lignin, sodium carbonate, si xal dheeha waa alkaline daciif ah, in
Marka midabaynta heerkulka sare ee 130%, way fududahay in la nadiifiyo, taasoo keentay midab khafiif ah iyo iftiin daciif ah.
(2) Sababtoo ah hoos u dhigista kala-baxa midabada kala firdhisan, luminta kooxda saldhigga timaha, dhacdadani waxay inta badan ku jirtaa qaabka azo ee dheeha.
(3) Kooxda phenolic ee qaab-dhismeedka molecular ee dheehyadu waxay sababtaa falcelinta ionic sababtoo ah ficilka alkali, iyo milanka biyaha ayaa la wanaajiyey, halka rinjiga sare uu daciif yahay si u dhigma. Badanaa, dareeraha kala firdhiya ee dheehku waa alkaline daciif ah sababtoo ah ku darida kala firdhisanaanta qubeyska midabaynta.
