Ibikoresho bya Shimi:

Acide acike, CH3COOH, ni ibara ritagira ibara, rihindagurika mubushyuhe bwibidukikije. Ifumbire isukuye, acide glacial acetique, ikesha izina ryayo isa na barafu isa na kirisita kuri 15,6 ° C. Nkuko bisanzwe bitangwa, aside irike ni 6 N igisubizo cyamazi (hafi 36%) cyangwa igisubizo cya 1 N (hafi 6%). Ibi cyangwa ibindi bihindagurika bikoreshwa mukongeramo aside irike ikwiye mubiribwa. Acide acike ni aside iranga vinegere, ubunini bwayo buri hagati ya 3,5 na 5,6%. Acide acetike na acetate biboneka mubihingwa byinshi hamwe ninyama zinyamanswa muke ariko kugaragara. Nibisanzwe bisanzwe bihuza metabolike, bikozwe nubwoko bwa bagiteri nka Acetobacter kandi birashobora guhuzwa rwose bivuye kuri dioxyde de carbone na mikorobe nka Clostridium thermoaceticum. Imbeba ikora acetate ku gipimo cya 1% yuburemere bwumubiri kumunsi.

Nkamazi adafite ibara hamwe numunuko wa vinegere ukomeye, ufite akamaro, ni ingirakamaro mumavuta, foromaje, inzabibu n'imbuto nziza. Acide nkeya cyane ya acetike nkiyi ikoreshwa mubiribwa, nubwo yashyizwe mubikorwa na FDA nkibikoresho bya GRAS. Kubera iyo mpamvu, irashobora gukoreshwa mubicuruzwa bitarimo Ibisobanuro nubuziranenge bwirangamuntu. Acide acike nikintu cyingenzi cya vinegere na aside pyroligneous. Mu buryo bwa vinegere, miliyoni zirenga 27 zongewe mu biribwa mu 1986, hafi yingana zingana zikoreshwa nka acide na flavours. Mubyukuri, aside acike (nka vinegere) yari imwe mubintu byambere bihumura neza. Vinegari ikoreshwa cyane mugutegura salade kwambara na mayoneze, ibirungo bisharira kandi biryoshye hamwe nisosi nyinshi ninjangwe. Zikoreshwa kandi mugukiza inyama no mukubika imboga zimwe. Mu gukora mayoneze, kongeramo igice cya acide acike (vinegere) kumunyu- cyangwa isukari-umuhondo bigabanya ubushyuhe bwa Salmonella. Amazi ahuza amazi ya sosiso akenshi arimo aside ya acetike cyangwa umunyu wa sodium, mugihe calcium acetate ikoreshwa mukubungabunga imiterere yimboga zaciwe, zafunzwe.

Gusaba:
Imikoreshereze ya acide acike mu nganda

1. Ikoreshwa muri synthesis yamabara na wino.

2. Ikoreshwa muguhuza impumuro nziza.

3. Ikoreshwa mu nganda za rubber na plastike. Ikoreshwa nkigikoresho cyo gutangiza no gutangira kubintu byinshi byingenzi bya polymer mubikorwa bya rubber na plastike (nka PVA, PET, nibindi).

4. Ikoreshwa nkibikoresho byo gutangiza amarangi hamwe nibice bifata

5. Ikoreshwa mu nganda zitunganya ibiribwa nkinyongera muri foromaje nisosi ndetse no kubungabunga ibiryo.

Gukoresha acide acike muri synthesis

1.Yakoreshejwe muri synthesis ya selile acetate. Cellulose acetate ikoreshwa muri firime zifotora hamwe nimyenda. Mbere yo kuvumbura firime ya selile ya selile, firime yo gufotora yahoze ikozwe muri nitrate, yari ifite ibibazo byinshi byumutekano.

2. Ikoreshwa nkigisubizo cya synthesis ya terephthalic. Paraxylene ihindurwamo aside aside ya terephthalic. Acide Terephthalic ikoreshwa muguhuza PET, ikoreshwa cyane mugukora amacupa ya plastike.

3. Byakoreshejwe cyane mubisubizo hamwe na alcool zitandukanye kugirango uhuze esters. Ibikomoka kuri acetate bikoreshwa cyane nk'inyongeramusaruro.

4. Byakoreshejwe muri synthesis ya vinyl acetate monomer. Monomer irashobora noneho guhindurwa kugirango ikore poly (vinyl acetate) nayo izwi nka PVA. pVA ifite uburyo bwinshi bwo gukoresha kuva mubuvuzi (bitewe na biocompatibilité na nanotehnologiya (nka stabilisateur) kugeza gukora impapuro).

5. Byakoreshejwe nkigisubizo muri reaction nyinshi za organocatalytic.

Gukoresha aside ya asike mu buvuzi

1. Acide acetike ikoreshwa mubuhanga bwitwa pigmented endoscopi, ubundi buryo bwa endoskopi isanzwe.

2. Acide acike ikoreshwa mugusuzuma neza kanseri y'inkondo y'umura n'ibisebe. Irakoreshwa kandi mugupima kanseri y'inkondo y'umura.

3. Acide acike ikoreshwa mukuvura otitis externa.

4. Acide acetike rimwe na rimwe ikoreshwa mu kuvura indwara ziterwa na bagiteri na fungal.

5. Mu bizamini bya laboratoire ku mbeba, aside irike yerekanwe kugabanya imishwarara yimbeba.

Gukoresha urugo rwa acide acike

1. Acide acike nikintu nyamukuru cya vinegere.

2. Vinegere ikoreshwa mu gutoragura imboga

3. Ikoreshwa mukwambara salade

4. Ikoreshwa muguteka. Ifata hamwe na soda yo guteka kugirango irekure gaze karuboni kugirango ibiryo bihinduke.

5.Yakoreshejwe nka antifungal agent.
