Taw qhia

Furfuryl cawv. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm furfuryl cawv:

Zoo:

Furfuryl cawv yog cov kua uas tsis muaj xim, tsw qab ntxiag, tsis muaj volatility.

Furfuryl cawv yog soluble hauv dej thiab kuj miscible nrog ntau cov kuab tshuaj organic.

Siv:

Txoj kev:

Tam sim no, furfuryl cawv feem ntau yog npaj los ntawm cov tshuaj synthesis. Ib txoj hauv kev uas feem ntau siv yog siv hydrogen thiab furfural rau hydrogenation nyob rau hauv muaj cov catalyst.

Cov ntaub ntawv kev nyab xeeb:

Furfuryl cawv yog suav tias muaj kev nyab xeeb nyob rau hauv kev siv dav dav, tab sis nws yuav ua rau muaj kev fab tshuaj rau qee tus neeg.

Tsis txhob sib chwv nrog furfuryl cawv rau ntawm qhov muag, tawv nqaij, thiab cov mucous daim nyias nyias, thiab yaug nrog dej kom ntau yog tias muaj kev sib cuag.

Furfuryl cawv yuav tsum tau saib xyuas ntxiv ntawm cov menyuam yaus txhais tes kom tsis txhob muaj kev sib tsoo lossis kov.
