Ke motsoako oa manyolo oo mokhoa oa oona oa lik'hemik'hale e leng C8H6BrN. E latelang ke tlhaloso ea sebopeho sa eona, tšebeliso, tlhahiso le tlhaiso-leseling ea polokeho:
Tlhaho:
- Ponahalo: Ha e na 'mala ho isa ho kristale e mosehla
- Sebaka se qhibilihang: likhato tse 64-68 tsa Celsius
- Sebaka se belang: 294-296 likhato tsa Celsius
- Boima ba 'mele: 1.51 g/ml
-Solubility: E qhibiliha hanyane ka metsing, e qhibiliha ka har'a metsoako e tloaelehileng e kang ethanol, ether le benzene.
Sebelisa:
Hangata e sebelisoa e le karolo e bohareng ea organic synthesis mme e ka sebelisoa ho lokisa metsoako e meng ea tlhaho. E ka sebelisoa ho kopanya meriana, ho kopanya chefo e bolaeang likokoanyana, le indastering ea dae le ea pente.
Mokhoa oa ho itokisa: Tokisetso ea
hangata e etsoa ka mehato e latelang:
1. Etsa p-methylbenzonitrile ka bromine tlas'a maemo a loketseng a ho itšoara ho hlahisa phenol.
Lintlha tsa Tšireletseho:
-ke motsoako o ka bang teng oa lintho tse phelang 'me o lokela ho tšoaroa ka hloko.
-Nakong ea ts'ebetso, tlhokomelo e lokela ho nkoa ho qoba ho kopana ka ho toba le letlalo, mahlo le pampiri ea ho hema.
-Apara lisebelisoa tse nepahetseng tsa ts'ireletso, joalo ka liatlana tsa lab le likhalase.
-E lokela ho sebetsoa sebakeng se nang le moea o motle 'me u qobe ho hema mouoane kapa lerole la eona.
-Haeba u hema kapa u kenngoa ka phoso, batla thuso ea bongaka hang-hang 'me u bontše setshelo kapa label bakeng sa boitsebiso.
Ka kopo hlokomela hore lik'hemik'hale leha e le life li lokela ho sebelisoa tlas'a maemo a loketseng a laboratori le ho latela mekhoa e sireletsehileng ea ts'ebetso.
