Acide acetike idafite ibara CAS 64-19-7 acide

Acide itagira ibara rya acide CAS 64-19-7 acide acetike Yerekanwe

Ibisobanuro bigufi:

Acide Acike

Acide acike, formulaire ya chimique CH3COOH, ni acide monobasic organique, igice cyingenzi cya vinegere. Acide ya acide ya anhydrous acide (acide glacial acetic acide) ni amazi ya hygroscopique idafite ibara. Ingingo yo gukonjesha ni 16,6 ° C (62 ° F) .Nyuma yo gukomera, ni ni kirisiti itagira ibara kandi igisubizo cyayo cyamazi ni acide acide kandi irashobora kwangirika cyane.Bora cyane kwangirika kwibyuma kandi amavuta arakaza amaso nizuru.

Acide acetike ikwirakwizwa cyane muri kamere, nko mumavuta yimbuto cyangwa amavuta yimboga. Acide acetike ibaho cyane cyane muburyo bwa esters.Mu nyama zinyamanswa, imyanda n'amaraso, aside acike ibaho muburyo bwa acide yubusa.Mikorobe nyinshi zirashobora guhindura organic zitandukanye ibintu muri acide acike binyuze muri fermentation.

Ohereza imeri kuri twe

Ibicuruzwa birambuye

Ibicuruzwa

Redox reaction

Kugabanya reaction

Acide acike irashobora kugabanuka kuri acetaldehyde na lithium aluminium hydride.

Oxidation reaction

Gutwika reaction yaacideni okiside reaction muburyo bwagutse kandi gutwikwa kwuzuye kwa acide acecite bizabyara karuboni ya dioxyde na pompe yamazi.

Igisubizo cyo gusimbuza

Esterification

Acide acike na Ethanol birashobora gukorerwa esterifike munsi ya catalizike ya acide sulfurike yibanze hamwe nubushyuhe kugirango bibyare acetate.

α-H halogenation reaction

Imbere ya fosifore itukura, halogene na acide acike irashobora gukorerwa α-H halogenation.Kurugero, acide acetike ikora na gaze ya chlorine ikorwa na fosifore itukura kugirango ikore aside chloroacetic

Kubura umwuma

Acide acike irashobora gukorerwa intermolecular dehydrasiyo.Molekile imwe ya acetike ikuraho itsinda -OH, mugihe irindi molekile ya acide ikuraho H, hanyuma amaherezo ya anhydride ya acetike.

Igisubizo hamwe na fosifore trichloride

Gushyushya aside ya acetike na fosifore trichloride birashobora gutera insimburangingo, reaction irashobora kubyara acetyl chloride na aside fosifori

Ibikurikira nigipimo cyigihugu cya Repubulika yUbushinwa kuri acide acetike yinganda:

Gushyira mu nganda ibiribwa

Mu nganda z’ibiribwa, aside ya asike ikoreshwa nka aside irike, uburyohe hamwe nogukora uburyohe mugukora vinegere ya sintetike, kuvanga acide acike kugeza kuri 4-5% hamwe namazi, ongeramo ibintu bitandukanye bihumura, uburyohe busa nubwa alcool, igihe cyo gukora ni kigufi kandi igiciro kirahendutse.Nkumukozi ukarishye, irashobora gukoreshwa mugihe cyibihingwa, mugutegura vinegere, ibiryo byabitswe, jelly na foromaje, ukoresheje muburyo bukurikije ibikenewe.Bishobora kandi gukoreshwa nk'inyongera uburyohe bwa vino ya koji, kandi dosiye ni 0.1 kugeza 0.3 g / kg.
