Selelekela

M-nitroaniline ke motsoako oa lintho tse phelang. Ke kristale e mosehla e nang le monko o mobe o ikhethang.

 

Tšebeliso e ka sehloohong ea m-nitroaniline e tšoana le dae e bohareng le e le thepa e tala bakeng sa liqhomane. E ka lokisa metsoako e meng ka ho itšoara ka metsoako e itseng, e kang metsoako ea nitrate e ka lokisoa ka ho itšoara ka nitric acid, kapa dinitrobenzoxazole e ka lokisoa ka ho itšoara ka thionyl chloride.

 

Mokhoa oa ho lokisa m-nitroaniline o ka fumanoa ka karabelo ea m-aminophenol ka asiti ea nitric. Mohato o khethehileng ke ho qhaqha m-aminophenol ka sulfuric acid e nang le nitric acid le ho tsosa karabelo, ebe e pholile le ho khanya ho fihlela qetellong ho fumana sehlahisoa sa m-nitroaniline.

 

Tlhahisoleseding ea polokeho: M-nitroaniline ke ntho e chefo e nang le phello e hlabang mahlong, letlalong le tsamaisong ea ho hema. Ho kopana le letlalo ho ka baka ho ruruha le bofubelu, 'me ho hema ka bongata ba mouoane kapa lerōle ho ka baka chefo. Apara likhalase tse sireletsang, liatlana, liphahlo tse sireletsang, le lintho tse phefumolohang ha u sebetsa, 'me u netefatse hore opereishene eo e etsoa maemong a nang le moea o motle. Tšoaetso leha e le efe e ka khonehang e lokela ho hlatsuoa hang-hang ka metsi a mangata 'me hang-hang e phekoloe ka tlhokomelo ea meriana. Ho feta moo, m-nitroaniline ea phatloha 'me e lokela ho behoa hole le malakabe a bulehileng le mocheso o phahameng.
