Acetoneyog cov kua tsis muaj kob thiab pob tshab, nrog tus yam ntxwv uas muaj zog uas muaj zog thiab cov kuab tshuaj tshwj xeeb. Nws yog dav siv hauv kev lag luam, science thiab thev naus laus zis, thiab lub neej txhua hnub. Hauv kev luam ntawv, acetone feem ntau siv los ua cov kuab tshuaj kom tshem cov kua nplaum rau cov khoom luam tawm, kom cov luam tawm tau sib cais. Hauv tshav pob ntawm biology thiab tshuaj, acetone tseem yog cov khoom siv tseem ceeb rau kev sib txuas ntawm ntau cov tebchaw, xws li steroid cov tshuaj seeb thiab alkaloids. Tsis tas li ntawd, Acetone tseem yog tus neeg saib xyuas kev ntxuav thiab hnyav. Nws tuaj yeem yaj ntau cov organic sib txuas thiab tshem tawm cov xeb, roj thiab lwm yam tsis txaus ntseeg nyob rau saum npoo ntawm cov hlau seem. Yog li ntawd, acetone tau siv dav hauv kev saib xyuas thiab tu cov tshuab ua haujlwm thiab khoom siv.
Cov qauv molecular ntawm acetone yog CH3COCH3, uas yog hom kev sib txuas ua ke ntawm Ketone. Ntxiv rau acetone, tseem muaj ntau lwm hom Ketone sib txuas rau hauv lub neej txhua hnub, xws li Butanone (CH3COCH2C3), propanone (Ch3coch3) thiab lwm yam. Cov Ketone sib txuas no muaj cov khoom siv lub cev sib txawv thiab tshuaj lom neeg, tab sis lawv txhua tus muaj ntxhiab tsw tshwj xeeb thiab saj ntawm cov kuab tshuaj tsw qab.
Kev tsim cov acetone feem ntau yog los ntawm kev rhuav tshem ntawm acetic acid nyob hauv lub xub ntiag ntawm catalysts. Cov tshuaj tiv thaiv cov tshuaj tiv thaiv tuaj yeem qhia raws li: ch3cooh → ch3coch3 + h2o. Ib qho ntxiv, tseem muaj lwm txoj hauv kev los tsim acetone, xws li cov decomparation ntawm actylene glycole cov khoom siv txhua hnub nrog kev xav tau siab txhua hnub hauv kev lag luam tshuaj. Nws yog dav siv nyob rau hauv cov qauv tshuaj, biology, luam ntawv, textile, nws tseem yog ib qho kev sib txuas lus tseem ceeb rau ntau cov teb hauv cov tshuaj, biology thiab lwm yam teb Cov.
Feem ntau, acetone yog ib qho tshuaj lom neeg cov khoom siv tshuaj khib nyiab zoo heev nrog rau kev thov kev cia siab dav. Txawm li cas los xij, vim nws lub siab qhib siab thiab cov yam ntxwv khaus, nws yuav tsum tau ua tib zoo siv hauv kev tsim khoom thiab siv kom tsis txhob muaj kev huam yuaj.
