Isingeniso

I-3-Chloro-4-bromobenzoic acid iyinhlanganisela ephilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-3-Chloro-4-bromobenzoic acid iyi-crystalline eqinile emhlophe kuya kokuphuzi okuphaphathekile.

- Ukunyibilika: Cishe ayincibiliki emanzini futhi inokuncibilika okuhle kuzincibilikisi zemvelo.

- Izakhiwo zamakhemikhali: I-3-chloro-4-bromobenzoic acid ingangena esterification, ishintshwe nokunye ukusabela kokunye ukusabela kwamakhemikhali.

 

Sebenzisa:

- Ukwakhiwa kwamakhemikhali: I-3-chloro-4-bromobenzoic acid ingasetshenziswa njengento yokuqala noma ephakathi ku-organic synthesis ukuze kuhlanganiswe ezinye izinhlanganisela eziphilayo.

- Izibulala-zinambuzane: Ingasetshenziswa futhi njengesinye sezithako kuma-insecticides.

 

Indlela:

Indlela yokulungiselela ye-3-chloro-4-bromobenzoic acid ingatholakala ngokusabela kwe-4-bromobenzoic acid ne-bromophenyl i-copper chloride (i-Cuprous bromochloride) eyenziwe nge-acetic acid.

 

Ulwazi Lokuphepha:

- Ubuthi: I-3-chloro-4-bromobenzoic acid ingaba yingozi kubantu futhi ingaba nemiphumela ecasulayo emehlweni, esikhumbeni nasendleleni yokuphefumula. Ukuxhumana okuqondile kufanele kugwenywe.

- Umthelela emvelweni: Sicela uhambisane nemithetho nezimiso zokuvikela imvelo ukuze ugweme ukungcolisa imvelo.

- Ukugcinwa nokubamba: Kufanele kugcinwe endaweni eyomile, epholile, kude nezinto ezivuthayo kanye nama-oxidants. Amagilavu ​​okuzivikela afanelekile, izibuko, nezingubo zokuzivikela kufanele zigqokwe lapho uphathwa noma usebenzisa.
