2-Chloro-3-bromo-5-nitropyridine (CAS# 5470-17-7)

Hordhac

Waa iskudhis organic ah oo caanaha kimikalkeedu yahay C5H2BrClN2O2.

Dabeecadda:

1. Muuqashada: Waa mid adag, badanaa budo crystalline jaale ah.

2. Solubility: Waxaa lagu milmi karaa dareerayaasha organic (sida dichloromethane, ether, iwm.), laakiin milanka biyuhu wuu hooseeyaa.

Isticmaal:

Waa xarun dhexe oo muhiim ah, taas oo si weyn loogu isticmaalo berrinka kiimikada.

1. Daroogadu synthesis: Waxa loo isticmaali karaa in lagu farsameeyo xeryahooda noolaha, sida dawooyinka, sunta cayayaanka, iwm.

2. Dye synthesis: Waxa loo isticmaali karaa in lagu sameeyo dheeha iyo midabada.

3. Isku-dhafka sunta cayayaanka: waxaa loo isticmaali karaa sunta cayayaanka synthetic iyo herbicides.

Habka Diyaarinta: Diyaarinta

Waxaa lagu fulin karaa falcelinta nitration-ka, tillaabooyinka gaarka ah waa sida soo socota:

1. Xaaladaha ku habboon, pyridine waxaa lagu falceliyaa nitric acid si loo helo pyridine-3-nitric acid.

2. Pyridine-3-nitric acid ayaa markaa lagu falceliyaa koobabka bromide si loo helo 3-bromopyridine.

3. Ugu dambeyntii, 3-bromopyridine waxaa lagu falceliyaa chloride silver si loo helo badeecada ugu dambeysa.

Macluumaadka Badbaadada:

1. waxa uu leeyahay cadho iyo suntan, fadlan iska ilaali taabashada maqaarka, indhaha iyo habdhiska neefsiga.

2. Marka lagu jiro hawlgalka, waa in ay xidhaan galoofyada ilaalinta, muraayadaha indhaha iyo maaskaro iyo qalabka kale ee ilaalinta shakhsi ahaaneed.

3. inta lagu jiro kaydinta iyo isticmaalka, waa in lagu kaydiyaa si gooni ah oo ka mid ah kuwa gubanaya, oksidayaasha iyo walxaha kale.

4. Marka aad tuurayso qashinka, fadlan raac xeerarka qashin-qubka deegaanka si loo yareeyo khatarta wasakhowga deegaanka.
