Mawu Oyamba

3,4,5-Trichloropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

 

Ubwino:

- Maonekedwe: 3,4,5-Trichloropyridine ndi madzi achikasu otumbululuka.

- Kusungunuka: Imasungunuka mu zosungunulira zina monga chloroform, benzene, ndi methanol.

- 3,4,5-Trichloropyridine ndi mankhwala amphamvu.

 

Gwiritsani ntchito:

- 3,4,5-Trichloropyridine nthawi zambiri amagwiritsidwa ntchito ngati chothandizira mu kaphatikizidwe ka organic, mwachitsanzo mu chlorination ndi aromatization zimachitikira.

- Itha kugwiritsidwanso ntchito ngati chopangira chapakatikati komanso chowonjezera pazinthu za polima.

 

Njira:

- Kukonzekera njira ya 3,4,5-trichloropyridine nthawi zambiri amagwiritsa ntchito zomwe chloropyridine ndi mpweya wa chlorine. Masitepe enieni amaphatikizapo kuziziritsa kusakaniza kwa zomwe zimachitika ndikuzichita pansi pamikhalidwe yodzaza ndi klorini kwa nthawi. Pambuyo pake, mankhwalawa amayeretsedwa ndi distillation.

 

Zambiri Zachitetezo:

- 3,4,5-Trichloropyridine imakwiyitsa komanso ikuwononga, kukhudzana ndi khungu ndi maso kuyenera kupewedwa, ndipo magolovesi oteteza ndi magalasi ayenera kuvala.

- Ikagwiritsidwa ntchito kapena kusungidwa, iyenera kusungidwa kutali ndi komwe kuli moto komanso kutentha kwambiri kuti isapse.

- Mukamagwiritsa ntchito 3,4,5-trichloropyridine, samalani ndi mpweya wabwino kuti musapumedwe ndi mpweya.

- Tsatirani malamulo oyenera komanso malangizo achitetezo pogwira kapena kutaya zinyalala.
