Txheej txheem cej luam khoom:
Cov phenols tuaj yeem muab faib ua cov phenols uas tsis hloov pauv thiab cov phenols uas tsis hloov pauv raws li seb lawv puas tuaj yeem raug distilled nrog cov pa.
Cov phenols uas yaj tau feem ntau yog hais txog cov monophenols uas muaj cov ntsiab lus kub qis dua 230°C. Cov phenols feem ntau yog los ntawm
los ntawm cov dej khib nyiab tsim tawm hauv kev ua roj refining, roj ntxuav, coking, papermaking, synthetic ammonia ntau lawm,
kev txuag ntoo, thiab kev lag luam tshuaj lom neeg. Phenols yog cov tshuaj lom heev, ua haujlwm ua cov tshuaj lom protoplasmic.
Cov concentration qis tuaj yeem ua rau cov protein tsis zoo, thaum cov concentration siab ua rau cov protein nag, ua rau v puas tsuaj ncaj qha
cov hlwb loj thiab cov tawv nqaij thiab cov ntaub so ntswg uas ua rau tawv nqaij lwj. Kev noj cov tshuaj phenol uas muaj kuab lom mus sij hawm ntev
dej yuav ua rau kiv taub hau, tawv nqaij tawm pob, khaus, ntshav tsis txaus, xeev siab, ntuav, thiab ntau yam tsos mob ntawm lub paj hlwb.
Cov tshuaj phenolic tau raug txheeb xyuas tias yog cov neeg txhawb nqa qog nqaij hlav hauv tib neeg thiab tsiaj txhu.
Cov Ntsiab Cai Khoom:
Hauv ib qho alkaline medium, cov phenolic compounds react nrog 4-aminoantipyrine. Nyob rau hauv lub xub ntiag ntawm potassium ferricyanide,
ib qho xim txiv kab ntxwv-liab antipyrine tau tsim. Lub cuab yeej ua qhov kev tshuaj xyuas ntau yam siv spectrophotometry.
