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 acike cyangwa umunyu wa sodium, mugihe calcium acetate ikoreshwa mukubungabunga imiterere yimboga zaciwe, zafunzwe.

Gusaba:

1.Yakoreshejwe muri synthesis y'amabara na wino.

2. Ikoreshwa muguhuza impumuro nziza.

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

4. Ikoreshwa nkibikoresho byo gutangiza amarangi hamwe nibice bifata

5. Ikoreshwa mu nganda zitunganya ibiryo nk'inyongera muri foromaje n'amasosi ndetse no kubungabunga ibiryo.

Acide acike - Umutekano

Umunwa LD50 ku mbeba: 3530mg / kg; LDso percutaneous inkwavu: 1060mg / kg; guhumeka thLC50 ku mbeba: 13791mg / m3. ruswa. Guhumeka ibicuruzwa biva mu kirere birakaza izuru, umuhogo hamwe n'inzira z'ubuhumekero. Birakaze cyane amaso. Kurinda, kwoza n'amazi atemba. Birabujijwe rwose kuvanga na okiside, alkali, imiti iribwa, nibindi. Ubike mububiko bukonje, buhumeka. Irinde umuriro nubushyuhe. Komeza ikintu. Ubike ukwe na okiside na alkalis.
