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.
Haddii hadda laguu sheego, dad badan ayaa ku wareeri doona, iyagoo leh ma garanayaan waxa kanu yahay, dadka qaarna xitaa waxay maqlaan magacyadooda si ay u qiyaasaan shaqadooda. Suurtagal ma tahay mowjadda qiyaasidda mawjada alaabtan?
Dhab ahaantii, waxaa jira magac aad loo yaqaan -acetic acid.
Isticmaalka dhabta ah,barafka acetic acidlaguma dabaqi doono warshadaha wax soo saarka. Taa bedelkeeda, sababtoo ah waa mid ka mid ah asiidhyada dabiiciga ah ee ugu muhiimsan adduunka, waxay leedahay meelo kale, ballaaran oo kala duwan oo codsi ah iyo channels codsi. Nuxurka
Jiritaankeedu ma aha oo kaliya inay noo ogolaato inaan helno miis cunto oo dhadhan fiican leh, laakiin sidoo kale waxay noo ogolaaneysaa inaan noqono kuwo ku habboon oo siman xagga dharka, guryaha, safarka, daawada, daawada, iwm, gaar ahaan isticmaalka warshadaha. Impoles acetic acid ayaa ka badan. Waa codsi aad u fiican.
Sida soo saarista dawooyinka sawir-qaadista, daabacaadda dharka iyo rinjiyeynta, warshadaha caagagga, warshadaha midabaynta, cuntooyinka sonkorta leh, fiber synthetic, iwm.
Sidaa darteed, dad badan ayaa og in acetic acid ay tahay sababtoo ah waxaan ka shaqeeyay ama wax ku bartay maadooyinka kiimikada la xiriira; dadka qaar ayaa lagu akhriyay shaxda halabuurka ee diyaarinta qaarkood; dadka qaar baa Fahamsan iyo wixi la mida.
Si kastaba ha ahaatee, inkasta oo ay leedahay adeegsi kala duwan oo ballaadhan, marka aad iibsanayso ice acetic acid, saaxiibada qaarkood waxay had iyo jeer dareemaan in ay jirto dhibaato qiimaha barafka ee ay iibsadeen. Dadka qaar waxay moodayaan inay qaali yihiin. Si la mid ah, dhammaantood waxay dareemayaan inay iibsadaan been abuur ama ay la kulmaan soosaarayaasha wadnaha madow.
