Intshayelelo

I-2,4-Dinitrophenyl ether yi-organic compound. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:

 

Indalo:

- 2,4-Dinitroanisole yikristale engenambala ukuya kumthubi nencasa ekhethekileyo ekrakra.

-Inonyibiliko oluphantsi kwiqondo lokushisa elisezantsi kwaye i-soluble kwii-solvents eziphilayo ezifana ne-ether, utywala kunye ne-ester.

-Izinzile ekukhanyeni, kubushushu kunye nomoya.

 

Sebenzisa:

- I-2,4-Dinitroanisole isetyenziswa kakhulu njengento eluhlaza kwidayi yepyrotechnic kwi-organic synthesis.

-Inokusetyenziswa nakwiindawo zedayi, ii-pigments, amayeza kunye nezitshabalalisi.

 

Indlela yokulungiselela:

Ukulungiswa kwe--2,4-dinitroanisole kunokuqhutyelwa nge-esterification reaction phakathi kwe-anisole kunye ne-nitric acid.

-Ngaphantsi kweemeko zokuphendula, i-anisole ishushu nge-nitric acid kunye ne-sulfuric acid ukuvelisa i-precipitate ye-2,4-dinitroanisole.

-Emva kokuphendula, imveliso ecocekileyo inokufumaneka ngokucoca, ukuhlamba kunye ne-crystallization.

 

Ulwazi ngoKhuseleko:

- I-2,4-dinitroanisole iyacaphukisa ulusu, amehlo kunye nomgudu wokuphefumula, kwaye ukudibanisa ngokuthe ngqo kufuneka kugwenywe.

-Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, izibuko zokhuseleko kunye nezikhuselo zobuso ngexesha lokusebenza.

-Xa usebenza ngaphakathi kwindlu, kuyimfuneko ukubonelela ngezixhobo ezifanelekileyo zokungenisa umoya ukuze ugweme ukukhupha umphunga okanye uthuli.

-Inkunkuma kufuneka ilahlwe ngokuhambelana nemigaqo yendawo kwaye kufuneka ingakhutshelwa kwindalo esingqongileyo.
