Metotia Gaosiga
Faʻaaogaina e pei o se vaʻaiga vaʻavaʻa, ma faʻaaogaina foi i le sauniuniga o le fluorescent whitening agent dye intermediates, ma faʻaaogaina i le gaosiga o le fluorescent whitening agent DT.
Metotia Gaosiga
Faʻaaogaina le p-chlorophenol e fai ma mea mata, 2-nitro-p-chlorophenol e mafai ona faia e ala i le faʻamaʻiina, ona faʻaitiitia lea e fai ai le p-chloro-o-aminophenol.
(1) Gaosiga o le 2-nitro-p-chlorophenol: Faʻaaogaina o le p-chlorophenol e fai ma mea mata, faʻamaʻi faʻatasi ma le nitric acid.Fa'aopopo lemu le p-chlorophenol fa'amama i totonu o le tane fa'afefete ma le 30% nitric acid, fa'atumauina le vevela ile 25-30℃, fa'aoso mo le tusa ma le 2 itula, fa'aopopo le aisa e malulu i lalo ole 20℃, fa'afefete, faamama, ma fufulu le keke faamama i Congo Red, o le oloa 2-nitrop-chlorophenol e maua.
(2) E lua auala mo le faʻaitiitia o le 2-nitro-p-chlorophenol.O le tasi o le faʻaitiitia i le sodium disulfide.Muamua, o le 30% sodium hydroxide solution ma le sulfur powder o loʻo faʻaaogaina e fai ai le sodium disulfide solution, ma le 2-nitro-p-phenol e faʻaopoopoina i le faʻatusatusa e tali i le 95-100°C, ma ua uma le tali.A maeʻa le faʻamamaina vevela, faʻafefete le filtrate i le vai susu, faʻamafanafana i le 20°C, faʻamama, ma fufulu le keke faʻamama i le neutrality e maua ai le oloa maeʻa 2-nitro-p-chlorophenol.
Ole lona lua ole auala ole fa'aitiitiga ole hydrogenation.I le i ai o se faʻamaʻi nickel, o le faʻamalologa o le 2-nitro-p-chlorophenol e faʻafetaui i le pH = 7 faʻatasi ai ma le sodium dihydrogen phosphate hydrate ma le sodium hydroxide aqueous solution i le hydrogen pressure o le 4.05Mpa ma le faʻaitiitia o le Hydrogenation i le 60.°C. A maeʻa le tali, faʻamalolo le mamafa, sui i le nitrogen, vevela i le 95°C, fetuutuunai pH=10.7 ma le sodium hydroxide, faaopoopo carbon activated ma le diatomaceous earth, faʻamalosi malosi, ma faamama.O le filtrate na fetuunai ile pH=5.2 (20°C) faʻatasi ai ma le faʻamaʻi o le hydrochloric acid, faʻamafanafana i le 0°C, fa'amama, fa'agogo, ma togafitia i le sodium bisulfite.Toe fai le fa'agaioiga, ona fa'amama lea i le 2.67kpa, ao mai vaega ninii ile 80.°C, ma faʻamago i latou e maua ai le oloa ma se fua o le 97.7%.
Le Talosaga Autu
O le faʻaaogaina autu o le p-chloro-o-aminophenol e pei o se vali vaeluaga, mo le saunia o le vailaʻau mordant RH, acid complex violet 5RN ma reactive dyes, ma isi, faʻapea foʻi ma le saunia o mea mataʻutia chlorzoxazone.
Fa'apipi'i, Teuina ma Felauaiga
O se vailaʻau mataʻutia, ma o loʻo faʻapipiʻiina i le 25kg uʻamea uʻamea, ma o le fale teu oloa e faʻafefe, maualalo le vevela ma mago, ma puipuia mai le susulu o le la.Taofi ese mai mea e maua mai ai le afi, ma teu ma felauaiga ese mai acids, oxidants, mea'ai faaopoopo, ma oxidants.
