2 5-DICHLORO-4-METHYLPYRIDINE （CAS # 886365-00-0)
Intangiriro
2,5-dichloro-4-methylpyriridine ni ifumbire mvaruganda hamwe na chimique C6H5Cl2N. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imiterere namakuru yumutekano:
1. Kamere:
-Ibigaragara: amazi adafite ibara cyangwa kirisiti ikomeye;
-Gukemuka: Gushonga mumashanyarazi nka ether, inzoga na hydrocarbone;
-Gushonga: -26 ° C;
-Ibintu bitetse: 134-136 ° C;
-Ubucucike: 1.36g / cm³.
2. Koresha:
-2,5-dichloro-4-methylpyriridine ni intera ikomeye hagati ya synthesis organique kandi ifite uburyo bwinshi bwo gukoresha mubijyanye n'ubuvuzi na chimie;
-Bishobora gukoreshwa mugutegura imiti yica udukoko, fungiside nibindi bintu kama;
-ishobora kandi gukoreshwa nka catalizator, surfactant hamwe n irangi.
3. Uburyo bwo gutegura:
-Uburyo bwo gutegura bwa 2,5-dichloro-4-methylpyriridine mubusanzwe tubonwa na chlorination reaction kuri pyridine.
-Urugero, pyridine irashobora gukoreshwa na fosifore oxychloride (POCl3) cyangwa fosifore tetrachloride (PCl4) munsi yikirere kitagira inert, hanyuma hagakurikiraho kuvura dechlorine kugirango ubone ibicuruzwa bigenewe.
4. Amakuru yumutekano:
-2,5-dichloro-4-methylpyriridine irakaze kandi ikabora amaso, uruhu nu myanya y'ubuhumekero. Fata amazi menshi ako kanya ukimara guhura hanyuma ushake ubufasha bwa muganga;
-koresha ugomba kwambara uturindantoki two kurinda, ibirahure birinda na mask yo gukingira;
-Irinde guhura na okiside ikomeye kugirango wirinde ingaruka mbi;
-Bika kure yumuriro, ubushyuhe nibikoresho byaka.
