Phenol yog ob qho tib si tsim tshuaj thiab tshuaj anatural. Koj tuaj yeem saj thiab tsw phenol nyob rau theem qis dua cov uas muaj feem cuam tshuam nrog kev phom sij. Phenol evaporates qeeb dua dej, thiab ib qho nruab nrab tuaj yeem tsim cov tshuaj nrog dej.
Tsis tas li ntawd, phenol nyob hauv koj lub cev ntev npaum li cas?
Phenol tuaj yeem pom hauv huab cua thiab dej tom qab tso tawm los ntawm kev tsim khoom, siv, thiab pov tseg cov khoom uas muaj phenol . Phenol nyob rau hauv av yog zoo li txav mus rau hauv av. Phenol yog tawg sai sai hauv huab cua, feem ntau tsis pub dhau 1-2 hnub.
Kuj Paub, yog phenol kua lossis khoom? Phenols zoo ib yam li cawv tab sis tsim muaj zog hydrogen bonds. Yog li, lawv yog soluble hauv dej ntau dua li cov dej cawv thiab muaj cov ntsiab lus kub siab dua. Phenols tshwm sim tsis muaj xim kua los yog dawb cov khoom khib nyiab nyob rau hauv chav tsev kub thiab tej zaum yuav muaj tshuaj lom thiab caustic.
Ib yam li ntawd, phenol puas ua rau mob qog noj ntshav?
Nyob ntawd yog tsis muaj pov thawj tias phenol ua rau mob cancer nyob rau hauv tib neeg.
phenol puas tuaj yeem tua koj?
Phenol yog siv los ua tshuaj tua kab mob thiab pom muaj nyob rau hauv cov khoom siv. Cov tawv nqaij raug ntau heev ua tau ua rau cov tawv nqaij kub hnyiab, daim siab puas tsuaj, tso zis tsaus nti, lub plawv dhia tsis zoo, thiab txawm tuag. Kev noj cov concentrated phenolcan tshuaj tsim cov kub hnyiab.

Dab tsi yog acidic ethanol ntau dua los yog phenol?
Hauv phenol, rub cov pz electrons los ntawm oxygen atom mus rau hauv lub nplhaib ua rau cov hydrogen atom ua ib feem zoo dua li nws muaj nyob rau hauv aliphatic alcohols. Qhov no txhais tau tias nws yooj yim dua ploj los ntawm phenol dua li nws yog los ntawm aliphatic cawv, yog li phenol muaj cov khoom muaj zog acidic dua li ethanol
Puas yog phenol tsawg acidic dua ethanol?
Phenol yog acidic ntau dua li ethanol vim tias phenoxide ion ruaj khov dua ethoxide ion vim resonance
Ib tsob ntoo evaporate dej ntau npaum li cas?
Thaum lub caij cog qoob loo, nplooj yuav hloov dej ntau zaus ntau dua li nws qhov hnyav. Ib daim av ntawm pob kws muab tawm txog 3,000-4,000 nkas loos (11,400-15,100 liters) dej txhua hnub, thiab tsob ntoo ntoo loj tuaj yeem hloov pauv 40,000 nkas loos (151,000 liters) ib xyoos twg
Puas yog cawv yog phenol?
Cawv yog cov organic compound uas nws cov molecule muaj ib lossis ntau pawg hydroxyl uas txuas ntxiv mus rau carbon atom. Phenol, ntawm qhov tod tes, yog ib qho sib xyaw ua ke ntawm pawg hydroxyl sib txuas ncaj qha mus rau pawg muaj ntxhiab hydrocarbon. Phenols yog cov xim tsis muaj xim nyob rau hauv daim ntawv ntawm crystals
Puas yog phenol react nrog dej?
Koj tuaj yeem paub txog phenol vim tias: Nws yog ib qho yooj yim insoluble hauv dej. Nws reacts withsodium hydroxide tov kom muab cov xim tsis muaj xim (thiab yog li yuav tsum yog acidic). Nws tsis tsim cov pa roj carbon dioxide nrog sodium carbonate lossis hydrogencarbonate kev daws teeb meem (thiab yog li yuav tsum tsis muaj zog acidic)
