Isingeniso
I-Trifluoromethoxyphenol. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
Ukubukeka: I-Trifluoromethoxyphenol iqinile engenambala ukuya kokuphuzi okuphaphathekile.
I-Solubility: Incibilika kuzincibilikisi eziphilayo njenge-ethanol, i-dimethylformamide, ne-methylene chloride, kodwa inokuncibilika okuphansi emanzini.
I-Acidity kanye ne-alkalinity: I-Trifluoromethoxyphenol i-asidi ebuthakathaka engakwazi ukuncibilika ngama-alkali.
Sebenzisa:
Ukwenziwa kwamakhemikhali: i-trifluoromethoxyphenol ivamise ukusetshenziswa ekuphenduleni kwe-organic synthesis futhi ingasetshenziswa njengento ebalulekile ephakathi nendawo noma evuselelayo.
Indlela:
I-Trifluoromethoxyphenol ingatholwa ngokusabela i-p-trifluoromethylphenol nge-methyl bromide. I-Trifluoromethoxyphenol ingatholwa ngokuncibilikisa i-trifluoromethylphenol ku-dispersant futhi yengeze i-methyl bromide, futhi ngemva kokusabela, ithatha isinyathelo esifanele sokuhlanza.
Ulwazi Lokuphepha:
I-Trifluoromethoxyphenol iyacasula futhi kufanele igwenywe ukuthintana nesikhumba namehlo.
Lapho usebenzisa noma ulungiselela, kufanele kuqashelwe izinyathelo zokuzivikela, njengokugqoka amagilavu okuzivikela, izibuko zokuphepha, nezingubo zokuzivikela.
Lapho uphatha noma ugcina, ukuthintana nezinto ezifana nama-oxidants, ama-acids, nama-alkali kufanele kugwenywe ukuze kuvinjelwe ukusabela okuyingozi.
Sicela ugcine i-trifluoromethoxyphenol kahle, kude nomlilo namazinga okushisa aphezulu, ukugwema ukusha noma ukuqhuma kwayo.
Uma kukhona ukungaphatheki kahle noma ingozi, sicela uxhumane nochwepheshe kusenesikhathi futhi ubhekane nakho ngokuhambisana nezinqubo zokusebenza zokuphepha ezifanele. …
