(Igipimo cyo gusaba 'gukoresha ibicuruzwa')
Imiterere ya kirisiti ya acide ya acetike yerekana ko molekile ihujwe na dimimeri (izwi kandi nka dimers) hamwe na hydrogène ya hydrogène, kandi ibipimo nabyo bibaho muri leta yumuyaga kuri 120 ° C. Ibipimo bifite umutekano muke, kandi byagaragaye ko acide carbokisike ifite uburemere buke bwa molekile nka acide formique na acide acetike ibaho muburyo bwa dimerike igabanya ubukana bwa X hamwe nuburyo bwo kugabanya uburemere bwa X. Iyo acide acike yashongeshejwe namazi, imigozi ya hydrogène hagati ya dimimeri iracika vuba. Izindi aside ya karubike yerekana dimerisation isa.

Imikoreshereze y'ibicuruzwa
Gukoresha inganda
1. Acide acetike nigicuruzwa kinini cyimiti, nimwe muma acide yingirakamaro. Ikoreshwa cyane cyane mukubyara anhydride ya acetike, acetate na selile selile. Polyetinyl acetate irashobora gukorwa muma firime no kuyifata, kandi ni nibikoresho fatizo bya fibre synthique Vinylon. Cellulose acetate ikoreshwa mugukora firime ya rayon na firime.
2. Esiteri ya acetike ikorwa na alcool nkeya ni umusemburo mwiza, ukoreshwa cyane mubikorwa byo gusiga amarangi. Kubera ko aside irike ishonga ibintu byinshi kama, ikoreshwa kandi mubisanzwe nkumuti ukungahaye (urugero nka okiside ya p-xylene kugirango itange aside terephthalic).
3. Acide acetike irashobora gukoreshwa mubisubizo bimwe na bimwe byo gutoragura no gusya, mugisubizo cya acide nkeya nka buffer (nka galvanised, electroless nikel plaque), mugice cya nikel cyaka nikel isa na electrolyte nkinyongera, mugisubizo cya passivation ya zinc, kadmium irashobora kunoza imbaraga zo guhuza firime ya passivation, kandi mubisanzwe bikoreshwa muguhindura aside ya pH.
4. Kubyara umusaruro wa acetate, nka manganese, sodium, gurş, aluminium, zinc, cobalt nindi myunyu yicyuma, ikoreshwa cyane nka catalizator, gusiga amarangi hamwe ninyongeramusaruro yinganda; Isasu rya acetate ni irangi ryamabara yayoboye umweru; Isasu rya tetraacetate ni synthesis ya reagent (urugero, tetraacetate ya sisitemu irashobora gukoreshwa nkigikoresho gikomeye cya okiside, itanga isoko ya acetoxy no gutegura ibinyabuzima byangiza umubiri, nibindi).
5. Acide acetike irashobora kandi gukoreshwa nka analytique reagent, synthesis organic, pigment hamwe na synthesis.
Gukoresha ibiryo
Mu nganda z’ibiribwa, aside ya asike ikoreshwa nka aside irike, uburyohe hamwe nimpumuro nziza mugihe ikora vinegere ya sintetike, acide acike ivangwa kugeza kuri 4-5% hamwe namazi, hanyuma hongerwamo ibintu bitandukanye. Uburyohe busa na vinegere ya alcool, kandi igihe cyo gukora ni gito kandi igiciro gihenze. Nkumuti usharira, urashobora gukoreshwa mugihe cyibihingwa, gutegura vinegere, kanseri, jele na foromaje, ukurikije umusaruro ukenewe kugirango ukoreshwe neza. Irashobora kandi guhimba impumuro nziza ya vino, imikoreshereze ni 0.1 ~ 0.3 g / kg.
