Acide ya Acetic, Ch3cooh, ni ibara ritagira ibara, rihindagurika ku bushyuhe bw'imbogamizi. Acide nziza, acide yijimye, abereyemo izina ryayo kuri barafu - nka kirisiti ya Crystalline kuri 15.6 ° C. Nkuko bisanzwe, acide acetike ni igisubizo cya 6 nqueous (hafi 36%) cyangwa igisubizo 1 (hafi 6%). Ibi cyangwa ibindi bikoresho bikoreshwa mugukongeramo aside acike kubiryo. Acide acetike ni acide iranga vinegere, kwibanda kuva kuri 3.5 kugeza 5.6%. Acide acetike na acetates bahari mubimera byinshi ningingo zinyamaswa muri nto ariko zimenyerewe. Nibisanzwe bya metabolic, byakozwe nubu bwoko bwa bagiteri nka acetobacter kandi barashobora kurwanywa burundu muri karuboni ya dioxyde ya karubon na mikorobe nka clogridium tronmoacetic. Imbonerahamwe ikora ku gipimo cya 1% yuburemere bwumubiri kumunsi.

Nkamazi atagira ibara afite imbaraga zikomeye, ziranga vinegere, ni ingirakamaro mu mavuta, foromaje, imizabibu n'imbuto. Acide ntoya cyane ya acetic nkuko ikoreshwa mubiryo, nubwo ikoreshwa na FDA nkibikoresho bya gras. Kubwibyo, birashobora gukoreshwa mubicuruzwa bitavuzwe nibisobanuro nibipimo byirangamuntu. Acide ya acetic nigice cyingenzi cyimizabibu na aside pyloallemous. Mu buryo bwa vinegere, lb zirenga miliyoni 27 zongerewe mubiribwa mu 1986, hamwe no kugereranywa kimwe na aclidulan hamwe n'abakozi bahindura. Mubyukuri, acide ya acetike (nka vinegere) yari imwe mubantu bafite uburyohe bwambere. Imizabibu ikoreshwa cyane mugutegura salade imyambarire ya salade na mayonnaise, ibibabi bisharira kandi byiza kandi byiza hamwe na catsups. Bakoreshwa kandi mugukiza inyama no mu kaga k'imboga zimwe. Mu gukora Mayoyonnaise, hiyongereyeho igice cya acide ya assic (vinegere) kumunyu- cyangwa isukari-umuhondo bigabanya ubushyuhe bwa Salmonella. Amazi ahuza ibiganiro akenshi akubiyemo acide ya acetike cyangwa umucu wa sodium, mugihe calcium acetate ikoreshwa mugurinda imiterere yimiterere yaka, isaka.

Gusaba:

1.bwe muri synthesis ya dyes na wino.

2. Ikoreshwa muri synthesis yimpumuro nziza.

3. Ikoreshwa muri reberi ninganda za plastiki. Ikoreshwa nkibintu byoroheje no gutangira kubintu byinshi byingenzi (nka Pva, Pet, nibindi) muri reberi hamwe ninganda za plastiki.

4. Ikoreshwa nkibikoresho byo gutangira kubibarana nibikorwa bifatika

5. Ikoreshwa mu nganda zitunganya ibiryo nkinyongera muri foromaje kandi sose kandi nkibiribwa.
