Meatotino tau vailaau:
O le Phenol o le tagata sili ona faigofie o le vasega o mea faʻaola o loʻo i ai se vaega hydroxyl o loʻo faʻapipiʻi i se mama benzene poʻo se faiga mama manogi sili atu ona lavelave.
E ta'ua foi o le carbolic acid poo le monohydroxybenzene, o le phenol o se mea e leai se lanu i le pa'epa'e tioata o le manogi suamalie, o lo'o iai le fatuga C6H5OH, e maua mai i le fa'amamaina o le ta koale ma o se mea e maua mai i ogaumu koko.
O le Phenol o lo'o i ai le tele o mea olaola, ma o vaifofo fa'afefete ua leva ona fa'aaogaina e fai ma fa'ama'i. I tulaga maualuga, e mafua ai le mu ogaoga o le paʻu; ose mea oona fa'aletino. O se vailaʻau mataʻutia taua mo le gaosiga o palasitika, vali, vailaʻau, syntans, ma isi oloa.
E liusuavai le Phenol pe tusa o le 43°C ma pupuna i le 183°C. O togi mama o loʻo i ai le mea faʻafefeteina o le 39°C, 39.5°C, ma le 40°C. O togi faʻapitoa e aofia ai le 82% -84% ma le 90% -92% phenol. O le tulaga fa'ameatino e tu'u mai ile 40.41°C. Ole kalave fa'apitoa ole 1.066. E fa'amavae i le tele o solvents organic. E ala i le faʻafefeteina o tioata ma faʻaopopo vai, e gaosia ai le phenol vai, lea e tumau pea le vai i le vevela masani. O le Phenol o loʻo i ai le meatotino e le masani ai o le tuʻuina atu o mea ola ma fausia ai se vailaʻau taua. E fa'aaogaina fo'i fa'apisinisi i le tipiina o suau'u ma mea fa'afefiloi ma fale pa'u. O le tau o isi vailaʻau faʻamaʻi ma vailaʻau faʻamaʻi e masani ona fuaina pe a faʻatusatusa i le phenol
Talosaga:
Phenol e masani ona faʻaaogaina i le gaosiga o resini phenolic, resins epoxy, filo nylon, palasitika, atinaʻe, faʻasao, insecticides, fungicides, vali, vailaʻau, mea manogi ma mea pāpā.
O se vailaʻau faʻasolosolo taua, lea e mafai ona faʻaaogaina e fai ai le phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, 2,4-D, adipic acid, phenolphthalein n-acetoxyaniline ma isi vailaʻau ma vailaʻau. , o lo'o i ai fa'aoga taua i mea fa'a-kemikolo, alkyl phenols, alava gaosia, palasitika, pa'u gaosia, pharmaceuticals, pesticides, mea manogi, vali, faʻaofuofu ma fale suauʻu faamamaina. E le gata i lea, e mafai foi ona faʻaaogaina le phenol e avea o se solvent, faʻataʻitaʻiga faʻataʻitaʻiga ma faʻamaʻi pipisi, ma o le vaifofo vai o le phenol e mafai ona tuʻueseese ai polotini mai DNA i luga o chromosomes i sela laau e faafaigofie ai le pisia o DNA.
