Iipropathi zeekhemikhali:

I-acetic acid, ch3cooh, lulwelo olungenabala, oluguqukayo kumaqondo obushushu. I-acid emsulwa, ecocekileyo ye-ACCECT, inika igama lakhe kwimbonakalo ye-crystalline nge-15,6 ° C. Ngokunikezelwa ngokubanzi, i-acetic acid sisisombululo se-6 n i-6 n i-3%) okanye isisombululo esi-1 (malunga ne-6%). Ezi okanye ezinye izilolo zisetyenziswa ukongeza isixa esifanelekileyo se-acetic acid yokutya. I-acetic acid yi-acid ye-acid ye-acid, ukugxininiswa kwalo ukusuka kwi-3.5 ukuya kwi-5.6%. I-acetic acid kunye ne-acetates zikhona uninzi lwezityalo kunye nezicubu zezilwanyana kwizixa ezincinci kodwa ezibonakalayo. Ziyi-Metabolic eziqhelekileyo, ziveliswa zii-bitlials njenge-acetobacter kwaye zinokwenziwa ngokupheleleyo kwikharbon dioksides njenge-thesmoridium thermocetium. I-Rat ichaza i-acetate nge-1% yobunzima bomzimba ngamnye ngosuku.

Njengolwelo olungenamibala olunamandla, i-pungent, i-odor yedivini yedivini, iluncedo kwibhotolo, itshizi, idiliya kunye neziqwengana zeziqhamo. Kukhulu kakhulu i-acetic acid ecocekileyo njengoko isetyenziswa ekutyeni, nangona ihlelwe yi-FDA njengezixhobo ze-GRA. Ngenxa yoko, inokuqeshwa kwiimveliso ezingagutyungelwanga ziinkcazo kunye nemigangatho yesazisi. I-acetic acid yeyona nto iphambili yediliya yediliya kunye ne-pyrogramous acid. Ngohlobo lweviniga, ngaphezulu kwe-27 yezigidi ze-LB zongezwa ukutya ngo-1986, malunga nezixa ezilinganayo ezisetyenziswa njengee-acidings kunye neearhente zokuzonwabisa. Ngapha koko, i-acetic acid (njenge-ivisgar) yenye yeearhente zokuqala. Iiviniga zisetyenziswa kakhulu ekulungiseleleni isaladi kunye ne-mayonnaise, i-choles emuncu kunye ne-specles kunye neesandi ezininzi kunye nekati. Ziyasetyenziswa kunyango lwenyama kunye nasemhlabeni wemifuno ethile. Kwimenyu ye-Mayonnaise, ukongezwa kwenxalenye ye-acetic acid (iviniga) kwityuwa- okanye iswekile-yolk inciphisa ukumelana nobushushu kweSalmonella. Ukubopha kwamanzi okubopha kweesoseji kuhlala kubandakanya i-acetic acid okanye ityuwa yayo yesodium, ngelixa i-calcium ye-calcium isetyenziselwa ukugcina ukuqulunqwa kwemifuno eyenziwe ngesiqwengana, i-wanmot yemifuno.

Isicelo:

1.Ukuhlala kwi-synthesis yedayi kunye ne-inki.

2. Isetyenziswe kwi-synthesis yeziqholo.

I-3. Isetyenziswe kwicandelo lerabha kunye neplastiki. Isetyenziselwa njengesinyibilikisi kunye nokuqala kwezinto ezininzi ezibalulekileyo (ezinjenge-PVA, isilwanyana, njl.njl) kumashishini erabha kunye namashishini eplagi.

I-4. Isetyenziswe njengesixhobo sokuqala sepeyinti kunye nezinto ezenzayo

5. Isetyenziswe kumzi-mveliso wokulungisa ukutya njengesongezelelo kwi-cheese kunye neesosi kunye nokugcinwa kokutya.

I-Acetic Acid - Ukhuseleko

I-OIL LL50 yeegundane: 3530mg / kg; I-Pecutaneous i-ldso yomvundla: 1060mg / kg; inhalation thlc50 yeempuku: 13791mg / m3. phawula. Ukuphefumla kwalo mfuneko yemveliso kuyacaphukisa impumlo, umqala kunye nephecana lokuphefumla. Ukucaphuka ngamandla emehlweni. Ukhuseleko, hlamba ngamanzi ahambayo. Kunqatshelwe ngokungqongqo ukudibanisa ne-oxidizer, ialkali, imichiza edliwayo, njl njl. Hlala kude nomlilo nobushushu. Gcina isitya esitywiniweyo. Gcina ngokwahlukeneyo kwii-oxidizers kunye ne-alkalis.
