Taw qhia
1-pentanol, tseem hu ua n-pentanol, yog cov kua tsis muaj xim. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 1-pentanol:
Zoo:
- Cov tsos mob: cov kua xim tsis muaj xim nrog cov ntxhiab tsw tshwj xeeb.
- Solubility: 1-pentanol yog soluble hauv dej, ethers thiab cawv solvents.
Siv:
- 1-Penyl cawv feem ntau yog siv rau hauv kev npaj cov tshuaj detergents, detergents thiab cov kuab tshuaj. Nws yog ib qho tseem ceeb ntawm cov khoom siv raw thiab siv dav hauv kev tsim cov surfactants.
- Nws kuj tseem siv tau los ua cov roj nplua nyeem thiab hnyav hauv cov xim thiab cov xim.
Txoj kev:
- 1-Penyl cawv feem ntau yog npaj los ntawm oxidation ntawm n-pentane. N-pentane tau txais cov tshuaj tiv thaiv oxidation los tsim valeraldehyde. Tom qab ntawd, valeraldehyde raug txo qis kom tau txais 1-pentanol.
Cov ntaub ntawv kev nyab xeeb:
- 1-Penyl cawv yog cov kua hluav taws xob, thiab yuav tsum tau them nyiaj rau qhov sib xyaw ntawm hluav taws xob thiab hluav taws xob zoo li qub thaum siv.
- Kev sib cuag nrog daim tawv nqaij tuaj yeem ua rau khaus, thiab kev sib cuag nrog daim tawv nqaij ntev yuav tsum zam. Cov cuab yeej tiv thaiv tus kheej tsim nyog yuav tsum hnav thaum tsim nyog.
- Kev nqus tau los yog kev tsis pom zoo ntawm 1-pentanol tuaj yeem ua rau kiv taub hau, xeev siab, thiab ua pa nyuaj.
