Taw qhia

Isoprenol yog ib qho organic compound. Nws yog cov kua uas tsis muaj xim nrog cov ntxhiab tsw. Cov hauv qab no yog kev qhia txog qee yam ntawm cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm isoprenol:

 

Zoo:

Isopentenol yog soluble hauv dej thiab qee cov kuab tshuaj organic xws li cawv thiab ethers.

Nws muaj cov ntxhiab tsw ntxhiab tsw thiab tuaj yeem ua rau khaus lossis kub hnyiab thaum nqus pa los yog sib cuag ntawm daim tawv nqaij.

High concentrations ntawm prenyl cawv tuaj yeem tsim cov khoom tawg.

 

Siv:

Nws tseem tuaj yeem siv rau hauv kev npaj cov txheej txheem, cov kuab tshuaj, thiab dyes.

 

Txoj kev:

Txoj kev npaj tseem ceeb ntawm isoprene cawv yog tau los ntawm epoxidation cov tshuaj tiv thaiv ntawm isoprenene, uas feem ntau yog catalyzed siv hydrogen peroxide thiab acidic catalysts.

 

Cov ntaub ntawv kev nyab xeeb:

Prenyl cawv yog khaus thiab yuav tsum tau siv nrog cov iav tiv thaiv kom zoo thiab tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.

Yuav tsum tau saib xyuas kom tsis txhob muaj oxidants, muaj zog acids thiab cov hauv paus thaum siv los yog khaws cia isoprenol kom tsis txhob muaj kev phom sij txaus ntshai.

Isopentenol muaj qhov taw tes qis qis thiab tawg txwv thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov hluav taws kub thiab ua haujlwm nyob rau hauv qhov chaw muaj cua zoo.
