Intangiriro
2,5-dimethylpyrazine ni ifumbire mvaruganda. Ibikurikira ni intangiriro kumiterere, ikoreshwa, uburyo bwo gutegura namakuru yumutekano ya 2,5-dimethylpyrazine.
Ubwiza:
2,5-Dimethylpyrazine ni ibara ritagira ibara ryijimye ry'umuhondo ryijimye hamwe n'umwotsi udasanzwe, imyunyu ngugu, n'ikawa.
Koresha:
Uburyo:
Gutegura 2,5-dimethylpyrazine birashobora gukorwa nuburyo butandukanye. Uburyo busanzwe ni ukubona ibicuruzwa bigenewe na ammonolysis ya thioacetylacetone ikurikirwa na cycleisation. Mubyongeyeho, hariho ubundi buryo bwa synthesis, nka nitroation yibintu bya karubone, kugabanya aside ya acili, nibindi.
Amakuru yumutekano:
2,5-Dimethylpyrazine ifite umutekano muke kubantu no kubidukikije mugihe gikoreshwa bisanzwe
- Iyo uhuye nuruhu n'amaso, birashobora gutera uburakari no gutwikwa, kandi hagomba gufatwa ingamba mugihe ubikoresheje, nko kwambara uturindantoki two gukingira hamwe na gogles.
- Irinde guhumeka imyuka cyangwa ivumbi mugihe cyo kubikora, kuko guhumeka igihe kirekire bishobora gutera uburakari.
- Guhura na okiside na acide zikomeye bigomba kwirindwa mugihe ubitse kugirango wirinde ingaruka mbi.
- Iyo uyijugunye, uyijugunye ukurikije amabwiriza abigenga kandi wirinde gusohoka mu bidukikije.
