2 5-DICHLORO-4-METHYLPYRIDINE (CAS# 886365-00-0)

Mawu Oyamba

2,5-dichloro-4-methylpyriridine ndi organic pawiri ndi mankhwala chilinganizo C6H5Cl2N. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, kapangidwe ndi chitetezo:

1. chilengedwe:

- Mawonekedwe: madzi opanda mtundu kapena olimba a crystalline;

-Kusungunuka: Kusungunuka mu zosungunulira organic monga ether, mowa ndi ma hydrocarbon;

-Kusungunuka: -26°C;

-Kuwira: 134-136 ° C;

- Kachulukidwe: 1.36g/cm³.

2. gwiritsani ntchito:

-2,5-dichloro-4-methylpyriridine ndi yofunika yapakatikati mu kaphatikizidwe organic ndipo ali osiyanasiyana ntchito m'munda wa mankhwala ndi umagwirira;

- Itha kugwiritsidwa ntchito pokonzekera mankhwala ophera tizilombo, fungicides ndi mankhwala ena achilengedwe;

-angagwiritsidwenso ntchito ngati chothandizira, surfactant ndi dye intermediates.

3. Njira yokonzekera:

-Njira yokonzekera ya 2,5-dichloro-4-methylpyriridine nthawi zambiri imapezeka ndi chlorination reaction pa pyridine.

-Mwachitsanzo, pyridine ikhoza kuchitidwa ndi phosphorous oxychloride (POCl3) kapena phosphorous tetrachloride (PCl4) pansi pa mpweya wochepa, wotsatiridwa ndi chithandizo cha dechlorination kuti apeze mankhwala omwe akufuna.

4. Zambiri Zachitetezo:

-2,5-dichloro-4-methylpyriridine imakwiyitsa komanso imawononga maso, khungu ndi kupuma. Sambani ndi madzi ambiri mutangokumana ndikupempha thandizo lachipatala;

-kugwiritsa ntchito ayenera kuvala magolovesi oteteza, magalasi oteteza ndi chigoba choteteza;

- Pewani kukhudzana ndi ma okosijeni amphamvu kuti mupewe zoopsa;

- Sungani kutali ndi moto, kutentha ndi zinthu zoyaka.
