Taw qhia
4-Methyl-4-(methylthio) pentane-2-one, tseem hu ua MPTK, yog cov organic compound. Hauv qab no yog cov lus qhia ntxaws ntxaws txog qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb ntawm MPTK:
Zoo:
- Cov tsos mob: MPTK zoo li tsis muaj xim lossis lub teeb daj.
- Solubility: MPTK yog soluble hauv qee cov organic solvents, xws li ether thiab chloroform, tab sis tsis zoo soluble hauv dej.
Siv:
- Kev siv tshuaj lom neeg: MPTK tuaj yeem siv los ua qhov nruab nrab ntawm cov organic synthesis rau kev sib txuas ntawm lwm cov organic sib txuas.
- Tshuaj tua kab: MPTK kuj tseem siv tau los ua raw khoom siv tshuaj tua kab hauv kev ua liaj ua teb.
Txoj kev:
- MPTK feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm sulfides nrog alkyl halides. Qhov sib thooj thioalkane tau txais los ntawm kev ua haujlwm ntawm alkyl halide nrog cov hlau sulfide (xws li sodium methyl mercaptan). Tom qab ntawd, los ntawm reacting thioalkane nrog acetic anhydride thiab acid chloride, MPTK khoom kawg yog generated.
Cov ntaub ntawv kev nyab xeeb:
- MPTK yuav tsum khaws cia kom deb ntawm qhov kub thiab txias thiab qhib nplaim taws, thiab muab cia rau hauv qhov chaw txias, qhuav qhov chaw kaw thiab kaw.
- Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog, suav nrog tshuaj tiv thaiv tsom iav thiab hnab looj tes, thaum siv MPTK kom tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag.
- Yuav tsum tau saib xyuas kom tsis txhob nqus plua plav lossis vapors thaum tuav MPTK, thiab lub tshuab ua pa yuav tsum hnav yog tias tsim nyog.
- Yog tias koj tsis pom zoo los yog ntsib nrog MPTK, nrhiav kev kho mob thiab nqa lub ntim lossis daim ntawv lo nrog koj kom koj tus kws kho mob tuaj yeem txheeb xyuas cov khoom xyaw.
