4-Amino-3,5-dibromobenzotrifluoride ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C7H4Br2F3N. E latelang ke tlhaloso ea sebopeho sa eona, tšebeliso, tlhahiso le tlhaiso-leseling ea polokeho:
Tlhaho:
-Ponahalo: E se nang 'mala kapa e mosehla o bobebe
-Solubility: E qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le dimethylformamide
- sebaka se qhibilihang: hoo e ka bang 115-117 ℃
- Sebaka se belang: hoo e ka bang 285 ℃
Sebelisa:
4-Amino-3,5-dibromobenzotrifluoride e na le boleng bo itseng ba ts'ebeliso mme hangata e sebelisoa likarolong tse latelang:
-E le karolo e bohareng ea organic synthesis, e ka sebelisoa ho lokisa metsoako e meng, joalo ka lithethefatsi, chefo e bolaeang likokoanyana le dae.
-Ka lipatlisiso tsa lik'hemik'hale, e ka sebelisoa e le reagent bakeng sa karabelo ea deprotection.
Mokhoa oa ho itokisa:
4-Amino-3,5-dibromobenzotrifluoride ka kakaretso e ka lokisoa ka mehato e latelang:
1.3,5-dibromobenzoic acid e ne e sebelisoa e le lisebelisoa tse tala ho lokisetsa 3,5-dibromobenzoic acid ester ka karabelo ea acidification.
2.3,5-dibromobenzoic acid ester e sebetsa ka motsoako oa nitrogen ho decarboxylate ho hlahisa 3,5-dibromobenzene acetyl chloride.
3. itšoara 3,5-dibromobenzotrifluoromethane le 3,5-dibromobenzotrifluoride ho hlahisa 4-Amino-3,5-dibromobenzotrifluoride.
4. Sehlahisoa se hloekileng se ka fumanoa ka crystallization kapa mekhoa e meng ea ho hloekisa.
Lintlha tsa Tšireletseho:
- 4-Amino-3,5-dibromobenzotrifluoride e hloka ho nka mehato e ts'oanang ea ts'ireletso nakong ea ts'ebetso le polokelo ho qoba ho kopana le letlalo le mahlo.
-le ho thibela ho hema kapa ho koalloa.
-Apara lisebelisoa tse nepahetseng tsa ts'ireletso tse kang liatlana tsa lik'hemik'hale, likhalase le liaparo tse sireletsang nakong ea ts'ebeliso.
-Ha ho ka etsahala hore ho be le kotsi kapa ho kopana ho sa tsotelleng, hlatsoa hang-hang ka metsi 'me u batle ngaka.
-Ha u sebetsana le motsoako, ka kopo latela mekhoa ea tšireletso.
