Taw qhia
4-Mercapto-4-methylpentan-2-one, tseem hu ua mercaptopentanone, yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Khoom: Mercaptopentanone yog xim tsis muaj xim rau cov kua daj daj, tsis muaj zog, thiab muaj ntxhiab tsw tshwj xeeb. Nws yog soluble hauv ntau cov kuab tshuaj organic xws li cawv, ethers, thiab esters ntawm chav tsev kub.
Kev Siv: Mercaptopentanone muaj ntau yam kev siv hauv cov tshuaj lom neeg. Nws tuaj yeem siv los ua cov khoom siv roj hmab, uas pab txhim kho cov cua sov thiab kev laus ntawm cov khoom siv roj hmab.
Txoj kev: Kev npaj ntawm mercaptopentanone feem ntau tau los ntawm cov tshuaj tiv thaiv synthesis. Ib txoj hauv kev npaj ntau yog los ua rau hex-1,5-dione nrog thiol los tsim mercaptopentanone.
Cov ntaub ntawv kev nyab xeeb: Mercaptopentanone yog cov kua nplaum nplaum, kom deb ntawm cov nplaim taws qhib thiab kub siab. Yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog daim tawv nqaij, qhov muag thiab nqus tau nws cov vapors thaum tuav. Mercaptopentanone yuav tsum tau siv thiab khaws cia rau hauv qhov chaw uas muaj cua zoo thiab kom deb ntawm hluav taws thiab oxidants.
