Isingeniso

I-2,4-Dinitrophenyl ether iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:

 

Imvelo:

- 2,4-Dinitroanisole iyikristalu engenambala ukuya kokuphuzi okuphaphathekile enokunambitheka okubabayo okukhethekile.

-Inokuncibilika okuphansi ekamelweni lokushisa futhi iyancibilika kuzincibilikisi zemvelo ezifana ne-ether, utshwala ne-ester.

-Izinzile ekukhanyeni, ekushiseni nasemoyeni.

 

Sebenzisa:

- I-2,4-Dinitroanisole isetshenziswa kakhulu njengempahla eluhlaza yodayi be-pyrotechnic ku-organic synthesis.

-Ingasetshenziswa nasezindaweni zamadayi, ama-pigments, imithi kanye nezibulala-zinambuzane.

 

Indlela Yokulungiselela:

Ukulungiswa kwe--2,4-dinitroanisole kungenziwa ngokusabela kwe-esterification phakathi kwe-anisole ne-nitric acid.

-Ngaphansi kwezimo zokusabela, i-anisole ishisa nge-nitric acid ne-sulfuric acid ukukhiqiza imvula ye-2,4-dinitroanisole.

-Ngemva kokusabela, umkhiqizo ohlanzekile ungatholakala ngokuhlunga, ukugeza kanye ne-crystallization.

 

Ulwazi Lokuphepha:

- I-2,4-dinitroanisole iyacasula isikhumba, amehlo kanye nomgudu wokuphefumula, futhi ukuxhumana okuqondile kufanele kugwenywe.

-Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko zokuphepha nezihlangu zobuso ngesikhathi sokusebenza.

-Uma usebenza endlini, kuyadingeka ukuhlinzeka ngezinsiza ezinhle zokuphefumula ukuze ugweme ukuhogela umhwamuko noma uthuli lwawo.

-Imfucuza kufanele ilahlwe ngokuhambisana nemithetho yendawo futhi akufanele ikhishelwe endaweni ezungezile.
