Intshayelelo

I-3,4,5-Trichloropyridine yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: 3,4,5-Trichloropyridine lulwelo olungenambala ukuya kumthubi.

- Ukunyibilika: Inyibilika kwezinye izinyibilikisi eziphilayo ezifana nekloroform, benzene, kunye nemethanol.

- I-3,4,5-Trichloropyridine yinto eyomeleleyo esisiseko.

 

Sebenzisa:

I-3,4,5-Trichloropyridine isoloko isetyenziswa njenge-catalyst kwi-organic synthesis, umz. kwi-chlorination kunye neempendulo ze-aromatization.

- Isenokusetyenziswa njenge-synthetic intermediate kunye ne-additive for polymer materials.

 

Indlela:

- Indlela yokulungiselela i-3,4,5-trichloropyridine ngokuqhelekileyo isebenzisa ukusabela kwe-chloropyridine kunye negesi ye-chlorine. Amanyathelo athile abandakanya ukupholisa umxube wokusabela kunye nokuwuphendula phantsi kweemeko ezizaliswe yiklorini ixesha elithile. Emva koko, imveliso ihlanjululwa nge-distillation.

 

Ulwazi ngoKhuseleko:

- I-3,4,5-i-Trichloropyridine iyacaphukisa kwaye iyancipha, ukudibanisa nesikhumba kunye namehlo kufuneka kugwenywe, kwaye iiglavu zokukhusela kunye neeglavu kufuneka zigqitywe.

- Xa isetyenziswe okanye igcinwe, kufuneka igcinwe kude nemithombo yomlilo kunye namaqondo okushisa aphezulu ukuphepha ukutsha kwayo.

- Xa usebenzisa i-3,4,5-trichloropyridine, nikela ingqalelo kwiimeko ezilungileyo zokungenisa umoya ukuze ugweme i-gas inhalation.

- Landela imimiselo efanelekileyo kunye nezikhokelo zokhuseleko xa uphethe okanye ulahla inkunkuma.
