Acetic acid tseem hu ua thib ob simplestcarboxylic kua qaub . Acetic acid Nws yog qhov nrov tshaj plaws paub vim nws siv hauv vinegar. Ib feem ntawm cov acetic acid Cov khoom siv yog siv los tsim cov yas acetate monomer (VAM), uas yog lub tsev thaiv los ua cov xim, nplaum, ntim thiab lwm yam.
Hauv qhov no, acetic acid pom nyob rau hauv dab tsi?
Cov khoom xyaw - Acetic Acid. Ib qho tshwm sim tshwm sim nyob rau hauv ntau yam nroj tsuag thiab txiv hmab txiv ntoo xws li txiv apples, txiv hmab txiv ntoo, txiv kab ntxwv, pineapples, thiab strawberries. Nws yog ib qho organicacid uas muab vinegar Nws qaub saj thiab txawv tsw. Nws yog tsim los ntawm ib tug txheej txheem fermentation.
acetic acid tsim li cas? Hnub no acetic acid yog tsim los ntawm cov txheej txheem tsim los ntawm cov tuam txhab tshuaj Monsanto hauv xyoo 1960; Nws suav nrog rhodium-iodine catalyzed carbonylation ntawm methanol (methyl cawv). Acetic acid yog ib qho organic kua qaub nrog cov tshuaj formula CH3COOH. Nws yog pom feem ntau invinegar.
Ib yam li ntawd, nws tau nug, dab tsi acetic acid siv rau?
Siv . Acetic acid yog ib qho tshuaj reagent rau kev tsim cov tshuaj chemical. Qhov loj tshaj plaws ib leeg siv acetic acid yog nyob rau hauv zus tau tej cov vinyl acetate monomer, ze li ntawm acetic anhydride thiab ester ntau lawm. Qhov ntim ntawm acetic acid siv nyob rau hauv vinegar yog comparatively me me.
Cov txiv qaub puas muaj acetic acid?
Qhov tseem ceeb tshaj qhov sib txawv ntawm txiv qaub kua txiv thiab vinegar yog hom kua qaub . Txiv qaub kua txiv ison nruab nrab tsib mus rau rau feem pua citric kua qaub . Nyob rau hauv cov nqe lus ntawm feem pua, nws nyob ntawm lub vinegar. Dawb vinegar nyiam muaj xya feem pua acetic acid , uas yog a qib siab dua lwm yam vinegars.
