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.

Oxidation reaction

Gutwika reaction yaacideni okiside reaction muburyo bwagutse no gutwikwa kwuzuye kwaacidebizabyara dioxyde de carbone hamwe numwuka wamazi.

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.

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.

Ingaruka ya acide acike ifitanye isano no kwibumbira hamwe kwa acide acide.Umuryango w’ubumwe bw’ibihugu by’Uburayi utanga ibisubizo bya aside irike ni urugero mu mbonerahamwe ikurikira:

Kwibanda (misa)	Ubwinshi	Gutanga amanota	R-Amagambo
10% –25%	1.67–4.16 mol / L.	Kurakara(Xi)	R36 / 38
25% –90%	4.16–14.99 mol / L.	Ruswa(C)	R34
> 90%	> 14.99 mol / L.	Ruswa(C)	R10, R35

Kubera umunuko ukabije hamwe numwuka wangirika, imikorere ya acide acecite yibanda kuri 25% igomba gukorwa munsi ya mask y'amaso. Umuti wa acide acetike, nka vinegere, ntacyo bitwaye.Nyamara, kwinjiza ibintu byinshi ya acide acetike yangiza ubuzima bwabantu ninyamaswa.

Gucunga ububiko

Ubike mu bubiko bukonje, buhumeka.Irinde umuriro nubushyuhe.Mu gihe cyo gukonjesha, ubushyuhe bwo kubika bugomba kubikwa hejuru ya 16 ℃ kugirango wirinde gukomera. Komeza ikintu gifunze cyane.Igomba kubikwa ukwayo na okiside na alkalis, kandi ntigomba kuvangwa. Koresha amatara adashobora guturika no guhumeka.Kubuza gukoresha ibikoresho bya mashini nibikoresho bikunda kugaragara.Ahantu ho guhunika hagomba kuba hafite ibikoresho byo kurekura byihutirwa nibikoresho bikwiye.
