Qaab dhismeedka crystal ee acetic acid waxay muujinaysaa in molecules ay ku xidhan yihiin dimers (sidoo kale loo yaqaan dimers) by bonds hydrogen, iyo dimers ayaa sidoo kale ka jira gobolka uumiga at 120 ° C. Dimers leeyihiin xasilooni sare, oo waxaa la caddeeyey in karboksylic acids oo leh miisaan yar oo molecular ah sida formic acid iyo acetic acid ay jiraan qaab ka mid ah qaabka dareeraha ah ee dareeraha ah xitaa qaabka dareeraha dareeraha ah. go'aaminta hoos u dhigista dhibicda qaboojinta iyo kala-duwanaanta raajada. Marka acetic acid lagu milmo biyo, xidhidhiyaha hydrogen ee u dhexeeya dimers ayaa si dhakhso ah u jebiya. Asiidhyada karboksilic ee kale waxay muujinayaan kala-bax isku mid ah.

Isticmaalka Alaabta
Isticmaalka warshadaha
1. acetic acid waa badeeco badan oo kiimiko, waa mid ka mid ah asiidhyada organic ugu muhiimsan. Waxaa inta badan loo isticmaalaa soo saarista acetic anhydride, acetate iyo cellulose acetate. Polyvinyl acetate waxaa laga samayn karaa filimaan iyo xabag, sidoo kale waa alaabta ceeriin ee fiilada synthetic ee Vinylon. Cellulose acetate waxaa loo isticmaalaa in lagu sameeyo rayn iyo filim sawir leh.
2. Acetic ester-ka ay sameeyeen alkolada hoose waa dareere aad u fiican, oo si ballaaran loo isticmaalo warshadaha rinjiga. Sababtoo ah aashitada acetic waxay milmisaa inta badan walxaha dabiiciga ah, sidoo kale waxaa badanaa loo isticmaalaa sida dareeraha organic (tusaale oksaydhka p-xylene si loo soo saaro terephthalic acid).
3. acetic acid waxaa loo isticmaali karaa in xal pickling iyo polishing qaar ka mid ah, in xal acidic liidata sida baffer ah (sida galvanized, platina electroless nikkel), ee semi-dhalaalaya nikkel dahaadhaysa electrolyte sida wax lagu daro, in xal passivation of Zinc, cadmium hagaajin karaa xoogga isku xidhka ee filimka passivation ah, oo caadi ahaan loo isticmaalo si ay u hagaajinta pH daciif ah.
4. wax soo saarka acetate, sida manganese, sodium, lead, aluminium, zinc, cobalt iyo cusbada kale ee birta ah, oo si ballaaran loo isticmaalo sida kicinta, dheeha dharka iyo daroogooyinka warshadaha hargaha; Acetate sunta rasaasta ah waa midabka ranjiga rasaasta cad; Lead tetraacetate waa reagent synthesis organic (tusaale ahaan, tetraacetate rasaasta waxaa loo isticmaali karaa sida walax oxidizing xoog leh, waxay bixisaa il acetoxy iyo diyaariyo xeryahooda organic macdanta rasaasta, iwm).
5. acetic acid waxa kale oo loo isticmaali karaa sida reagent gorfaynta, synthesis organic, pigment iyo synthesis daroogada.
Isticmaalka cuntada
Warshadaha cuntada, acetic acid waxa loo isticmaalaa sidii aysiidh ahaan, wakiilka dhadhanka iyo udgoonka marka la samaynayo khalka synthetic, acetic acid waxa lagu qasi karaa 4-5% biyo, iyo walxo dhadhan oo kala duwan ayaa lagu daraa. Dhadhanku wuxuu la mid yahay khalka khamriga, wakhtiga wax-soo-saarkuna waa gaaban yahay qiimuhuna waa raqiis. Sida wakiilka dhanaan, waxaa loo isticmaali karaa xawaash isku dhafan, diyaarinta khal, qasacadaysan, jelly iyo farmaajo, sida waafaqsan baahida wax soo saarka ee isticmaalka habboon. Waxa kale oo ay ka koobnaan kartaa ur udgoonka khamriga fooxa, qadarka isticmaalka waa 0.1 ~ 0.3 g / kg.
