Taw qhia

α-Terpineol yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm α-terpineol:

 

Zoo:

α-Terpineol yog cov kua tsis muaj xim nrog cov ntxhiab tsw tshwj xeeb. Nws yog ib yam khoom uas tsis muaj zog uas yog soluble hauv cov kuab tshuaj organic, tab sis nws yuav luag insoluble hauv dej.

 

Siv:

α-Terpineol muaj ntau yam kev siv. Nws feem ntau yog siv los ua cov khoom xyaw hauv cov khoom qab zib thiab cov tshuaj tsw qab los muab cov khoom muaj ntxhiab tsw tshwj xeeb.

 

Txoj kev:

α-Terpineol tuaj yeem ua ke los ntawm ntau txoj hauv kev, ib qho ntawm cov kev siv feem ntau yog tau los ntawm oxidation ntawm terpenes. Piv txwv li, oxidizing terpenes rau α-terpineol tuaj yeem siv tau siv cov tshuaj oxidizing xws li acidic potassium permanganate lossis oxygen.

 

Cov ntaub ntawv kev nyab xeeb:

α-Terpineol tsis muaj kev phom sij txaus ntshai nyob rau hauv kev siv dav dav. Raws li cov organic compound, nws yog volatile thiab flammable. Thaum siv, yuav tsum tau saib xyuas kom tsis txhob cuam tshuam nrog lub qhov muag, tawv nqaij, thiab siv. Nyob rau hauv rooj plaub ntawm cov tawv nqaij los yog ob lub qhov muag, yaug nrog dej kom ntau. Tsis txhob siv thiab khaws cia ze ntawm qhov hluav taws kub, thiab tswj kom muaj qhov chaw ua haujlwm zoo.
