Tilmaamaha tayada (GB/T 1628-2008)

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.

Acid acid, oo sidoo kale loo yaqaano acetic acid (36%-38%), glacial acetic acid (98%), formula kiimikaad CH3COOH, waa monic acid organic, qaybta ugu muhiimsan ee khalka. Aashitada anhydrous ee saafiga ah (glacial acetic acid) waa hygroscopic adag oo aan midab lahayn oo leh barta qaboojinta 16.6 ° C (62 ° F) oo noqda crystals aan midab lahayn ka dib markii la adkeeyo. Xalka aqueous waa daciif aashitada iyo nabaad guurka, iyo uumiga ayaa ka cadhaysiinaya indhaha iyo sanka.

Glacial acetic acid (maaddada saafiga ah), ie, anhydrous acetic acid, ka samaysan organic. Waxay ku adkeysaa baraf heerkul hoose waxaana badanaa loo yaqaannaa glacial acetic acid. Ballaarinta mugga inta lagu jiro adkeynta waxay keeni kartaa weelka inuu dillaaco. Barta tooshku waa 39 ℃, xadka qaraxa waa 4.0% ~ 16.0%, iyo fiirsashada ugu badan ee la ogolyahay ee hawadu kama badna 25mg/m3. Ashitada saafiga ah ee acetic acid waxay ku barafoobi doontaa kiristaalo u eg barafka oo ka hooseeya barta dhalaalka, sidaas darteed anhydrous acid waxaa sidoo kale loo yaqaannaa glacial acetic acid.

Waxaa la arki karaa in labadoodu aysan isku mid ahayn, barta iftiimaya ee acetic acid waa 39 ℃, xadka qaraxa waa 4.0% ~ 16.0%, iyo xoojinta ugu badan ee la oggol yahay ee hawadu kama badna 25mg/m3, taas oo iska leh. alaabta khatarta ah, iyo acetic acid ma aha alaabo khatar ah.
