3 4-Dihydroxybenzonitrile (CAS# 17345-61-8)

3 4-Dihydroxybenzonitrile (CAS# 17345-61-8) isingeniso

I-3,4-Dihydroxybenzonitrile iyinhlanganisela yezinto eziphilayo. Inamaqembu amabili e-hydroxyl kanye neqembu elilodwa elibambele leqembu le-nitrile.

Izakhiwo: Iyancibilika kwezinye izincibilikisi eziphilayo njenge-ethanol, i-ether ne-chloroform, engancibiliki emanzini. Iyazinza emoyeni, kodwa ingase isabele lapho ihlangana nama-oxidizing agents aqinile.

Sebenzisa:
I-3,4-Dihydroxybenzonitrile ivame ukusetshenziswa njengendawo ephakathi ku-organic synthesis.

Indlela:
I-3,4-Dihydroxybenzonitrile ingatholakala ngokunciphisa i-p-nitrobenzonitrile. Indlela ethile yokulungiselela ingase ihlanganise ukusabela kwe-p-nitrobenzonitrile ngama-ion ayoni noma i-nitrite ukuyinciphisa ukuze yakhe i-3,4-dihydroxybenzonitrile.

Ulwazi Lokuphepha:
I-3,4-Dihydroxybenzonitrile ngokuvamile iphephile ukusetshenziswa ngaphansi kwezimo zaselabhorethri ezivamile, kodwa okulandelayo kufanele kuqashelwe:
Gwema ukuthinta isikhumba namehlo, futhi ugweme ukuhogela uthuli noma amagesi;
Izinto zokuzivikela kufanele zigqokwe ngesikhathi sokusebenza, njengamagilavu ​​aselabhorethri nezibuko zokuzivikela;
Ngesikhathi sokusetshenziswa noma ukugcinwa kwayo, ukuthintana nama-oxidants aqinile kanye nemithombo yokuthungela kufanele kugwenywe ukuze kuvinjelwe ukusabela okuyingozi;
Gcina i-3,4-dihydroxybenzonitrile esitsheni esingangeni moya, kude nomlilo namazinga okushisa aphezulu.
