Isingeniso

I-3,4-Dichloronitrobenzene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- I-3,4-Dichloronitrobenzene iyikristalu engenambala noma ikristalu ephuzi ekhanyayo enephunga elinamandla lokufutha.

- Ayincibiliki emanzini ekamelweni lokushisa, kodwa iyancibilika kuzincibilikisi eziningi eziphilayo.

 

Sebenzisa:

- I-3,4-Dichloronitrobenzene ingasetshenziswa njenge-reagent yamakhemikhali njenge-substrate yokusabela kwe-nitrosylation.

- Ingasetshenziswa futhi njengesandulela sokuhlanganiswa kwezinye izinhlanganisela eziphilayo, njenge-glyphosate, isibulala-zinambuzane.

 

Indlela:

I-3,4-I-Dichloronitrobenzene ivamise ukulungiselelwa ngokuxutshwa kwe-nitrobenzene. Indlela ethile yokulungiselela ingasebenzisa ingxube ye-sodium nitrite ne-nitric acid, bese isabela ne-benzene ngaphansi kwezimo ezifanele zokusabela. Ngemuva kokusabela, umkhiqizo ohlosiwe uhlanzwa nge-crystallization nezinye izinyathelo.

 

Ulwazi Lokuphepha:

I-3,4-Dichloronitrobenzene inobuthi futhi ingase ibangele ukulimala empilweni yomuntu. Ukuchayeka, ukuhogela, noma ukumunca le nto kungabangela ukucasuka kwamehlo, ukuphefumula kanye nesikhumba.

- Le nhlanganisela kufanele igcinwe endaweni enomoya omuhle, eyomile, epholile, kude nezinto ezivuthayo kanye nama-oxidizing.
