Isingeniso

I-3,4,5-Trichloropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: 3,4,5-Trichloropyridine uketshezi olungenambala kuya kokuphuzi okuphaphathekile.

- Ukunyibilika: Incibilika kwezinye izinyibilikisi zemvelo njenge-chloroform, benzene, ne-methanol.

- 3,4,5-Trichloropyridine iyinhlanganisela eyisisekelo eqinile.

 

Sebenzisa:

I-3,4,5-Trichloropyridine ivame ukusetshenziswa njenge-catalyst ku-organic synthesis, isb ekuphenduleni kwe-chlorination kanye nephunga elimnandi.

- Ingasetshenziswa futhi njengokwenziwa okuphakathi nendawo kanye nesengezo sezinto ze-polymer.

 

Indlela:

- Indlela yokulungiselela ye-3,4,5-trichloropyridine ivamise ukusebenzisa ukusabela kwe-chloropyridine negesi ye-chlorine. Izinyathelo ezithile zibandakanya ukupholisa ingxube yokusabela nokusabela ngaphansi kwezimo ezigcwele i-chlorine isikhathi esithile. Kamuva, umkhiqizo uhlanzwa nge-distillation.

 

Ulwazi Lokuphepha:

- I-3,4,5-Trichloropyridine iyacasula futhi ibola, ukuthintana nesikhumba namehlo kufanele kugwenywe, futhi amagilavu ​​okuzivikela kanye nezibuko kufanele kugqokwe.

- Uma isetshenziswa noma igcinwa, kufanele igcinwe kude nemithombo yomlilo kanye namazinga okushisa aphezulu ukuze kugwenywe ukuvutha kwayo.

- Uma usebenzisa i-3,4,5-trichloropyridine, naka izimo ezinhle zokungenisa umoya ukuze ugweme ukuhogela igesi.

- Landela imithethonqubo efanele kanye neziqondiso zokuphepha lapho uphatha noma ulahla imfucuza.

 

  • Okwedlule:
