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, haragga, rinjiga, biraha warshadaynta iyo caagag.
Ashitada Acetic waa karboksilic acid fudud iyo reagent kiimiko oo muhiim ah.Elebrium waxaa sidoo kale loo isticmaalaa in lagu sameeyo polyethoethyls ee acetate iyo polyetate ee xabagta filimka filimka filimka, iyo sidoo kale fiilooyinka synthetic iyo dhar badan.Waxaa inta badan loo isticmaalaa in lagu soo saaro alaabta sida ethyl acetate, acetate, acetate, iyo chlorine-album acid.Waa shey ceeriin ah oo muhiim u ah fiber synthetic, xabagta, daawada, sunta cayayaanka iyo midabada.Sidoo kale waa dareere aad u fiican.Waxay kaloo aad caan uga tahay warshadaha.
Acetic acid waxaa loo isticmaali karaa sida nidaamiyayaal acidic ah, wakiilada acidification, pickles, wakiilada korodhka dhadhanka, dhir udgoon, iwm. Sidoo kale waa wakiilka wanaagsan ee anti-microbiological, taas oo inta badan ay sabab u tahay taas oo hoos u dhigi karta pH ee pH ilaa ** microorganisms.
Acitic acid waa codsi hore oo laga isticmaalo dalkayga, kaas oo inta badan loo isticmaalo xawaash isku dhafan, caanaha, qasacadaysan, farmaajo, jelly, iwm. Marka loo isticmaalo xawaash, waxaad ku qasi kartaa biyaha 4% ilaa 5% xal, waxaadna ku dari kartaa waxay ku daraysaa noocyo kala duwan.Cabbitaannada khalka laga sameeyay oo ah wakiilka dhadhanka dhanaan, oo lagu kabo agab caafimaad oo saafi ah ayaa loo yaqaan *nooca* saddex qarni oo cabitaanno ah.
Kordhi macluumaadka:
Diyaarinta acetic acid: Waxa lagu dari karaa hab-samaynta gacanta iyo halsano bakteeriyada.Habka isku-dhafka noolaha, taas oo ah, isticmaalka halsano bakteeriyada, kaliya waxay ka dhigan tahay 10% wax soo saarka adduunka oo dhan, laakiin weli waa hab muhiim u ah soo saarista acetic acid, gaar ahaan khalka, sababtoo ah xeerarka badbaadada cuntada ee meelo badan ayaa qeexaya. in khalka cuntada ku jira uu yahay bayoloji.Nidaamka sharciga, iyo habka halsano waxa loo qaybiyaa habka halsano hawada iyo habka halsano anaerobic.
Xaaladda oksijiin badan, bakteeriyada khalka ayaa soo saari karta acetic acid cuntooyinka ay ku jiraan aalkolada.Caadi ahaan isticmaal khamriga tufaaxa ama khamriga isku qasaya badarka, malt, bariiska ama baradhada si aad u khamiiriso.Isla'egyada kiimikaad ee ay khamiiriyaan bakteeriyadani waa:
C?HOH + O?→ CH?COOH + H?O
Qaar ka mid ah xubnaha bakteeriyada anaerobic, oo ay ku jiraan qaar ka mid ah xubnaha genus Ritula, waxay si toos ah ugu beddeli karaan sonkorta ethanol iyada oo aan u baahnayn ethanol dhexdhexaad ah.
