Intangiriro

2,6-dimethylpyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya 2,6-dimethylpyridine:

 

Ubwiza:

2,6-Dimethylpyridine ni amazi atagira ibara afite impumuro nziza.

 

Koresha:

2,6-Dimethylpyridine ifite porogaramu zitandukanye:

1. Irashobora gukoreshwa nka catalizator na reagent muburyo bwa synthesis synthesis.

2. Ikoreshwa nkibikoresho fatizo mugutegura amarangi, fluorescents nibikoresho kama.

3. Ikoreshwa nkibishishwa kandi ikuramo, ikoreshwa cyane mubikorwa byimiti myinshi ninganda zimiti.

 

Uburyo:

2,6-Dimethylpyridine ikorwa kenshi na reaction ya acetofenone na Ethyl methyl acetate.

 

Amakuru yumutekano:

1. Ifite impumuro mbi kandi igomba kwirindwa kumarana igihe kirekire no kwirinda guhumeka imyuka cyangwa imyuka.

2. Gants zo gukingira, indorerwamo n imyenda ikingira bigomba kwambara mugihe cyo gukora.

3. Irinde guhura na okiside ikomeye na acide zikomeye kugirango wirinde ingaruka mbi.

4. Iyo ubitse, kontineri igomba gufungwa cyane, kure yumuriro nubushyuhe bwo hejuru.
