Acide Acike

Acide acike, formulaire ya chimique CH3COOH, ni acide monobasic organique, igice cyingenzi cya vinegere. Acide ya acide ya anhydrous acide (acide glacial acetic acide) ni amazi ya hygroscopique idafite ibara. Ingingo yo gukonjesha ni 16,6 ° C (62 ° F) .Nyuma yo gukomera, ni ni kirisiti itagira ibara kandi igisubizo cyayo cyamazi ni acide acide kandi irashobora kwangirika cyane.Bora cyane kwangirika kwibyuma kandi amavuta arakaza amaso nizuru.

Acide acetike ikwirakwizwa cyane muri kamere, nko mumavuta yimbuto cyangwa amavuta yimboga. Acide acetike ibaho cyane cyane muburyo bwa esters.Mu nyama zinyamanswa, imyanda n'amaraso, aside acike ibaho muburyo bwa acide yubusa.Mikorobe nyinshi zirashobora guhindura organic zitandukanye ibintu muri acide acike binyuze muri fermentation.

Ibicuruzwa

Gushyira mu nganda ibiribwa

Mu nganda y'ibiribwa,acideikoreshwa nka acide, agent uburyohe hamwe nogukora uburyohe mugukora vinegere ya sintetike, kuvanga aside acetike kugeza kuri 4-5% hamwe namazi, ongeramo ibintu bitandukanye bihumura neza, uburyohe busa nubwa alcool, igihe cyo gukora ni gito kandi igiciro kirahendutse.Nkumukozi usharira, irashobora gukoreshwa mugihe cyibihingwa, mugutegura vinegere, ibiryo byafunzwe, jelly na foromaje, ukoresheje muburyo bukurikije ibikenewe. , kandi ibipimo ni 0.1 kugeza 0.3 g / kg.

Igisubizo hamwe na ammonia

Acide acike irashobora kwongerwaho na gaze ya ammonia munsi ya catalizike ya lipase, kandi hydroxyl groupe ya acide acike isimburwa nitsinda rya amino kugirango ikore acetamide.

Fermentation ibera muminara yuzuyemo ibiti cyangwa amakara.Ibikoresho fatizo birimo inzoga bitonyanga hejuru yumunara kandi umwuka mwiza winjira muburyo busanzwe cyangwa ku gahato uva hepfo. Ubwinshi bwumwuka mwinshi butuma iki gikorwa kirangira mubyumweru bike , kugabanya cyane igihe gisabwa cyo gukora vinegere.

Otto Hromatka na Heinrich Ebner babanje gusaba ko hategurwa vinegere ivuye mu muco w’umuco wa bagiteri w’amazi mu 1949. Muri ubu buryo, inzoga zasembuwe kuri acide acetike ihora ikurura kandi umwuka ugashyirwa mu gisubizo mu buryo bw’ibibyimba. Ukoresheje ubu buryo. , vinegere irimo aside 15% ya acetike irashobora gutegurwa muminsi ibiri cyangwa itatu.

Ibikurikira nigipimo cyigihugu cya Repubulika yUbushinwa kuri acide acetike yinganda:

Gucunga ubwikorezi

Igihe ntarengwa cyo gutwara gari ya moshi niki gicuruzwa ni ugukoresha imodoka ya tank itangwa n’umushinga wa aluminium kugirango woherezwe, kandi igomba kumenyeshwa ishami ryabigenewe kugira ngo iyemeze mbere yo koherezwa.Ku bwikorezi butabitswe na gari ya moshi, bugomba guteranyirizwa hamwe bikurikiza neza imbonerahamwe y’ibicuruzwa bihuye neza muri “Amategeko yo gutwara ibicuruzwa biteje akaga” ya Minisiteri ya Gari ya moshi.Ibipfunyika bigomba kuba byuzuye kandi gupakira bigomba kuba bifite umutekano mugihe cyoherejwe.Mu gihe cyo gutwara abantu, menya neza ko kontineri idatemba, igwa, igwa cyangwa ngo yangiritse. Ikamyo ya tank (tank) ikoreshwa mu gutwara igomba kuba ifite urunigi rwo hasi. . inzira yagenwe, kandi ntuhagarare ahantu hatuwe no mubice bituwe cyane.

Gucunga ububiko

Ubike mu bubiko bukonje, buhumeka.Irinde umuriro nubushyuhe.Mu gihe cyo gukonjesha, ubushyuhe bwo kubika bugomba kubikwa hejuru ya 16 ℃ kugirango wirinde gukomera. Komeza ikintu gifunze cyane.Igomba kubikwa ukwayo na okiside na alkalis, kandi ntigomba kuvangwa. Koresha amatara adashobora guturika no guhumeka.Kubuza gukoresha ibikoresho bya mashini nibikoresho bikunda kugaragara.Ahantu ho guhunika hagomba kuba hafite ibikoresho byo kurekura byihutirwa nibikoresho bikwiye.
