Ntshiab acetone thiab acetone yog ob qho tib si sib xyaw ntawm carbon, hydrogen, thiab oxygen, tab sis lawv cov khoom thiab kev siv tuaj yeem sib txawv heev. Txawm hais tias ob qho tib si tshuaj feem ntau hu ua "acetone, "lawv qhov sib txawv tau pom meej thaum xav txog lawv cov peev txheej, cov qauv tshuaj, thiab kev siv tshwj xeeb.

Peb yuav tsum paub qhov txawv ntawm cov ntshiab acetone thiab acetone. Ntshiab acetone yog cov xim tsis muaj xim, tsis muaj kuab lom nrog cov ntxhiab tsw ntxhiab tsw. Nws yog feem ntau siv nyob rau hauv cov ntsia thawv polish tshem tawm vim nws muaj peev xwm yaj cov resin tivthaiv nyob rau hauv ntsia thawv polish. Tsis tas li ntawd, ntshiab acetone yog siv los ua cov kuab tshuaj rau cellulose acetate, nrog rau lwm cov khoom siv cob. Nws kuj yog ib qho tseem ceeb muaj nyob rau hauv kev tsim ntau yam tshuaj thiab cov kuab tshuaj.

Ntawm qhov tod tes, acetone yog ib lo lus dav dav siv los piav txog ib pawg ntawm cov tebchaw uas suav nrog ob qho tib si ntshiab acetone thiab lwm yam sib xws nrog cov khoom sib txawv. Acetone feem ntau yog tsim los ntawm decomposition ntawm acetic acid thiab methane ntawm qhov kub thiab txias. Nws kuj pom muaj nyob rau hauv qhov, raws li ib tug by-product ntawm lub anaerobic digestion ntawm organic teeb meem.

Nyob rau hauv cov nqe lus ntawm nws lub cev muaj zog, ntshiab acetone muaj ib tug tsawg boiling point tshaj dej, thaum acetone muaj ib tug boiling point. Qhov sib txawv ntawm qhov kub kub no tuaj yeem cuam tshuam rau lawv cov kev siv thiab tshuaj lom neeg. Piv txwv li, ntshiab acetone yuav boil ntawm 56.2 ° C, ua rau nws tsim nyog rau siv nyob rau hauv cov ntsia thawv polish tshem tawm, thaum acetone muaj ib tug siab boiling point ntawm 80.3 ° C, ua rau nws tsis volatile thiab ntau haum rau siv nyob rau hauv ntau yam kev lag luam txheej txheem.

Thaum nws los txog rau lawv cov kev siv, cov ntshiab acetone feem ntau yog siv los ua cov kuab tshuaj rau cov ntsia thawv polish tshem tawm vim nws muaj peev xwm ua tau zoo yaj cov tshuaj tiv thaiv hauv cov ntsia thawv polish. Nws kuj yog siv los tsim ntau yam tshuaj thiab cov kuab tshuaj raws li tau hais ua ntej. Ntawm qhov tod tes, acetone yog siv rau hauv ntau yam kev lag luam xws li kev tsim cov acetic acid, cellulose acetate, thiab lwm yam khoom siv cob. Nws kuj yog siv los ua tus neeg saib xyuas rau ntau qhov chaw hlau vim nws muaj peev xwm tshem tawm cov roj thiab lwm yam impurities.

Cov ntshiab acetone thiab acetone yog cov khoom sib txawv uas muaj qee yam zoo sib xws tab sis sib txawv hauv lawv lub cev thiab kev siv. Pure acetone yog cov kua dej tsis haum uas feem ntau siv los ua cov kuab tshuaj rau cov ntsia thawv polish tshem tawm thiab tsim ntau yam tshuaj thiab cov kuab tshuaj. Ntawm qhov tod tes, acetone yog hais txog ib pab pawg sib txuas nrog cov khoom sib txawv uas tau siv ntau yam kev lag luam xws li kev tsim cov acetic acid, cellulose acetate, thiab lwm yam khoom siv cob. Kev nkag siab qhov sib txawv ntawm ob yam khoom no yog qhov tseem ceeb rau kev siv tau zoo hauv ntau yam kev siv.
