2-3-Dimethyl pyrazine (CAS#5910-89-4)

Mawu Oyamba

2, 3-Dimethylpyrazine ndi organic pawiri. Zotsatirazi ndikuyambitsa zina mwazinthu zake, ntchito, njira zopangira ndi chidziwitso chachitetezo:

Ubwino:

2, 3-Dimethylpyrazine ndi kristalo wopanda mtundu mpaka wachikasu. Lili ndi fungo la acetone kapena ethers ndipo limatha kusungunuka mu mowa ndi zosungunulira za ether.

Gwiritsani ntchito:

2, 3-Dimethylpyrazine imagwiritsidwa ntchito makamaka ngati chiyambi cha organic synthesis. Itha kugwiritsidwa ntchito ngati chothandizira cha esterification, carboxylation ndi enolation pansi pamikhalidwe yamchere.

Njira:

2, 3-dimethylpyrazine ikhoza kukonzedwa ndi SN2 m'malo mwa ethyl iododide kapena ethyl bromide ndi 2-aminopyrazine. Zomwe zimachitika nthawi zambiri zimachitika pamaso pa sing'anga yamchere, monga sodium ethoxide. Zitachitika, chandamale mankhwala akamagwira crystallization kapena m'zigawo.

Zambiri Zachitetezo:

2, 3-Dimethylpyrazine ili ndi kawopsedwe kakang'ono pansi pamikhalidwe yogwiritsidwa ntchito bwino. Monga mankhwala, kukhudzana ndi khungu, maso, ndi kupuma kungayambitse mkwiyo. Njira zodzitetezera nthawi zonse za labotale monga kuvala magolovesi oteteza mu labotale, magalasi, ndi zida zoteteza kupuma ziyenera kutsatiridwa zikagwiritsidwa ntchito. Ngati mwakhudzana mwangozi kapena pokoka mpweya, sambani kapena chotsani malo omwe akhudzidwawo mwamsanga ndikupempha uphungu.
