Cov khoom siv acetone

Acetoneyog cov kua uas tsis muaj xim thiab pob tshab, nrog cov yam ntxwv tsis muaj zog thiab muaj kuab lom tshwj xeeb saj. Nws yog dav siv hauv kev lag luam, kev tshawb fawb thiab thev naus laus zis, thiab lub neej txhua hnub. Hauv kev luam ntawv, acetone feem ntau yog siv los ua cov kuab tshuaj tshem tawm cov kua nplaum ntawm lub tshuab luam ntawv, kom cov khoom luam tawm tuaj yeem sib cais. Hauv kev lag luam biology thiab tshuaj, acetone kuj yog ib qho tseem ceeb raw khoom rau kev sib txuas ntawm ntau lub tebchaw, xws li steroid hormones thiab alkaloids. Tsis tas li ntawd, acetone kuj yog ib qho tshuaj ntxuav tau zoo thiab hnyav. Nws tuaj yeem yaj ntau cov organic tebchaw thiab tshem tawm xeb, roj thiab lwm yam impurities ntawm qhov chaw ntawm cov hlau. Yog li, acetone tau siv dav hauv kev saib xyuas thiab tu cov tshuab thiab khoom siv.

 

Cov mis molecular ntawm acetone yog CH3COCH3, uas belongs rau ib hom ketone tebchaw. Ntxiv nrog rau acetone, kuj tseem muaj ntau yam ketone lub cev hauv lub neej txhua hnub, xws li butanone (CH3COCH2CH3), propanone (CH3COCH3) thiab lwm yam. Cov ketone compounds no muaj cov khoom sib txawv ntawm lub cev thiab tshuaj lom neeg, tab sis lawv txhua tus muaj cov ntxhiab tsw tshwj xeeb thiab saj ntawm cov kuab tshuaj.

 

Kev tsim cov acetone feem ntau yog los ntawm kev decomposition ntawm acetic acid nyob rau hauv lub xub ntiag ntawm catalysts. Qhov sib npaug ntawm cov tshuaj tiv thaiv tuaj yeem qhia tau tias: CH3COOH → CH3COCH3 + H2O. Tsis tas li ntawd, tseem muaj lwm txoj hauv kev los tsim acetone, xws li decomposition ntawm ethylene glycol nyob rau hauv lub xub ntiag ntawm catalysts, hydrogenation ntawm acetylene, thiab lwm yam. Acetone yog ib tug niaj hnub tshuaj raw khoom uas muaj kev xav tau siab nyob rau hauv kev lag luam tshuaj. Nws yog dav siv nyob rau hauv kev lag luam tshuaj, biology, luam ntawv, textile, thiab lwm yam. Ntxiv rau kev siv los ua cov kuab tshuaj, nws kuj yog ib qho tseem ceeb raw khoom rau kev sib txuas ntawm ntau lub tebchaw hauv cov tshuaj, biology thiab lwm yam kev lag luam. .

 

Feem ntau, acetone yog cov khoom siv tshuaj muaj txiaj ntsig zoo nrog rau kev siv dav dav. Txawm li cas los xij, vim nws qhov kev hloov pauv siab thiab cov yam ntxwv flammability, nws yuav tsum tau ua tib zoo tuav hauv kev tsim khoom thiab siv kom tsis txhob muaj xwm txheej.
