Taw qhia
4-Hydroxy-3-methylacetophenone, tseem hu ua 4-hydro-3-methyl-1-phenyl-2-butanone, yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
4-Hydroxy-3-methylacetophenone yog cov kua tsis muaj xim lossis daj daj nrog lub aroma tshwj xeeb. Nws yog ib qho polar compound uas yog soluble hauv cawv, ethers, ketones, thiab ester solvents.
Siv:
Txoj kev:
Muaj ntau txoj hauv kev npaj rau 4-hydroxy-3-methylacetophenone, thiab ib qho ntawm cov txheej txheem tau txais los ntawm oxidation cov tshuaj tiv thaiv ntawm carbonyl compounds. Cov kauj ruam tshwj xeeb suav nrog reacting 3-methylacetophenone nrog iodine los yog sodium hydroxide kom tau txais cov iodozolate los yog hydroxyl, uas yog tom qab ntawd hloov mus rau 4-hydroxy-3-methylacetophenone los ntawm kev txo cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
4-Hydroxy-3-methylacetophenone yog suav tias yog kev nyab xeeb hauv kev siv dav dav. Raws li cov organic compound, nws tseem muaj qee qhov kev phom sij. Kev sib cuag nrog daim tawv nqaij thiab nqus tau nws cov vapors tuaj yeem ua rau khaus thiab ua rau muaj kev fab tshuaj. Thaum tuav cov khoom sib xyaw no, yuav tsum tau saib xyuas kom siv cov khoom tiv thaiv tus kheej (xws li hnab looj tes thiab looj tsom iav) thiab xyuas kom muaj cua zoo. Nyob rau hauv rooj plaub ntawm kev sib chwv los yog nqus tau pa, cov tshuaj yuav tsum tau muab yaug lossis tshem tawm tam sim ntawd thiab yuav tsum tau nrhiav kev kho mob. Thaum khaws cia thiab tuav, thov ua raws li kev ntsuas kev nyab xeeb kom tsis txhob muaj xwm txheej.
