Acide acike

ibisobanuro bigufi:

Ni acide organic monic, igice cyingenzi cya vinegere.Acide ya anhydrous acetike (acide glacial acetic acide) ni amazi ya hygroscopique idafite ibara, igisubizo cyayo cyamazi ni acide nkeya kandi yangirika, kandi irashobora kwangirika cyane kubutare.

 (Igipimo cyo gusaba 'gukoresha ibicuruzwa')

Imiterere ya kirisiti ya acide acetike yerekana ko molekile ihujwe na dimimeri (izwi kandi nka dimers) hamwe na hydrogène, kandi ibipimo nabyo bibaho mumyuka yumuyaga kuri 120 ° C. Ibipimo bifite umutekano muke, kandi byagaragaye ko karubasi. acide ifite uburemere buke bwa molekile nka acide formic na acide acetike ibaho muburyo bwa dimimeri muburyo bukomeye, bwamazi cyangwa na gaze binyuze muburyo bwo kugena uburemere bwa molekile mukugabanya ingingo no kugabanya X-ray.Iyo acide acike yashongeshejwe namazi, imigozi ya hydrogène hagati ya dimimeri iracika vuba.Izindi aside ya karubike yerekana dimerisation isa.

Gukoresha inganda

1. acide acetike nigicuruzwa kinini cyimiti, nimwe muma acide kama ikomeye.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. ester estetike yakozwe na alcool nkeya ni solvent nziza, ikoreshwa 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), muri nikel-yaka nikel isa na electrolyte nkinyongera, mugisubizo cya passivation ya zinc , kadmium irashobora kunoza imbaraga zo guhuza firime ya passivation, kandi mubisanzwe ikoreshwa muguhindura pH yo kwiyuhagira acide.

4. kubyara umusaruro wa acetate, nka manganese, sodium, gurş, aluminium, zinc, cobalt nindi myunyu yicyuma, ikoreshwa cyane nka catalizator, gusiga amarangi hamwe ninganda zongera uruhu;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 acike 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.
