Selelekela

Benzidine (eo hape e tsejoang e le diphenylamine) ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

 

Boleng:

- Ponahalo: Benzidine ke 'mala o mosoeu ho isa ho o mosehla oa kristale.

- Solubility: ha e qhibilihe ka metsing, e qhibiliha ka har'a lihlapolli tsa tlhaho tse kang joala, ethers, jj.

- Letšoao: Ke electrophile e nang le thepa ea electrophilic substitution reaction.

 

Sebelisa:

- Benzidine e sebelisoa haholo tšimong ea organic synthesis. E ka sebelisoa e le thepa e tala le ea maiketsetso ea mahareng bakeng sa lik'hemik'hale tse kang dae, li-pigments, polasetiki, joalo-joalo.

 

Mokhoa:

- Benzidine ka tloaelo e lokiselitsoe ka ho fokotsa dinitrobiphenyl, ho felisoa ha mahlaseli a haloaniline, joalo-joalo.

- Mekhoa ea sejoale-joale ea ho itokisa e kenyelletsa motsoako oa li-amine tse nkhang hamonate, joalo ka karabelo ea substrate diphenyl ether le amino alkanes.

 

Lintlha tsa Tšireletseho:

- Benzidine e chefo 'me e ka baka ho halefa le ho senya' mele oa motho.

- Ha u sebetsana le benzidine, tlhokomelo e lokela ho nkoa ho qoba ho kopana le letlalo le ho hema, 'me lisebelisoa tsa tšireletso tse kang liatlana, likhalase tse sireletsang, le limaske tse sireletsang li lokela ho apesoa ha ho hlokahala.

- Ha benzidine e kopana le letlalo kapa mahlo, e lokela ho hlatsoa hang-hang ka metsi a mangata.

- Ha u boloka le ho sebelisa benzidine, ela hloko ho qoba ho kopana le lintho tse phelang le li-oxidants ho thibela mollo kapa ho phatloha.
