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:
Ukusetyenziswa kwe-acetic acid kumzi mveliso

1. Isetyenziswe kwi-synthesis yedayi nee-inki.

2. Isetyenziswe kwi-synthesis yeziqholo.

I-3. Isetyenziswe kumzi-mveliso werabha kunye neplastiki. Isetyenziselwa njengesinyibilikisi kunye nokuqala kwezinto ezininzi ezibalulekileyo kumashishini erabha kunye nemizi-mveliso yeplastiki (njenge-PVA, isilwanyana, njl.njl.).

I-4. Isetyenziswe njengesixhobo sokuqala sepeyinti kunye nezinto ezenzayo

5. Isetyenziswe kumzi-mveliso wokulungisa ukutya njengesongezo kwitshizi kunye neesosi kunye nokutya okuphezulu.

Ukusetyenziswa kwe-acetic acid kwi-synthesis synthesis

1.Ukuhlala kwi-synthesis ye-seluplose ecetate. I-selsulose i-secetate isetyenziswa kwiifilimu zefoto kunye neempawu. Phambi kokuqulunqa ifilimu ye-icetate ye-icetate, ifilimu yefoto esetyenziselwa ukwenza nge-nitrate, eyayineengxaki ezininzi zokhuseleko.

2. Isetyenziswe njengesinyibilikisi ye-synthesis ye-terephthayic acid. I-Paraxyne ine-oxidlid ukuya kwi-Terephthayic i-Acid. I-Terephthayic Acid isetyenziselwa ukuqesha isilwanyana, eso sisetyenziselwa ukwenza iibhotile zeplastiki.

3. Isetyenziswe ngokubanzi kwimpendulo enamachaphaza ahlukeneyo okuyifumana ii-Esters. I-Acetate Drivatives isetyenziswa ngokubanzi njengezongezo zokutya.

4. Isetyenziswe kwi-synthesis ye-vinyl ye-vinyl. I-monomer inokuthi emva koko i-polymermermed ukuba yenze i-poly (vinyl acetate) ikwabizwa ngokuba yi-PVA. I-PVA inoluhlu olubanzi lwezicelo ezivela kumayeza (ngenxa ye-bimomatible kwi-nanotechnology (njenge-stabilizer) ekwenzeni iphepha).

5. Isetyenziswe njenge-solvent kwizimisele ezininzi ze-organocalytic.

Ukusetyenziswa kwe-acetic acid kunyango

I-1. I-acetic acid isetyenziswa kwindlela ebizwa ngokuba yi-pigscopy ye-pigscopy, eyinye enye kwi-endoscopy eqhelekileyo.

2. I-acetic acid isetyenziselwa uvavanyo olubonakalayo lomhlaza wesibeleko kunye nezilonda. Ikwasetyenziselwa ukukhangela umhlaza wesibeleko.

I-3. I-acetic acid isetyenziselwa ukuphatha i-otitis exnerna.

I-4. I-acetic acid ngamanye amaxesha isetyenziselwa ukuphatha usulelo lwentsholongwane kunye nefungi.

I-5. Kwimvavanyo lwelebhu kwiimpuku, i-acetic acid ibonisiwe ukunciphisa impendulo ye-inflommatory kwimpuku.

Ukusetyenziswa kwekhaya kwe-acetic acid

1. I-Acetic Acid yeyona icandelo eliphambili leviniga.

I-2. Iviniga isetyenziselwa imifuno yokufumana imifuno

I-3. Isetyenziselwa ukunxiba isaladi

4. Isetyenziswe kwinkqubo yokubhaka. Inika ingxelo ngesoda yokubhaka ukukhupha i-carbon diokside yerhasi yokwenza ukutya.

5. UKUSETYENZISWA NJENGOMGAQO-NKQUBO WE-AntiFIFIFUNLal.
