Isingeniso
I-2,5-dimethylpyrazine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,5-dimethylpyrazine.
Ikhwalithi:
I-2,5-Dimethylpyrazine iyikristalu engenambala ukuya kokuphuzi ngokukhanyayo enephunga elikhethekile lentuthu, i-nutty, nekhofi.
Sebenzisa:
Indlela:
Ukulungiswa kwe-2,5-dimethylpyrazine kungenziwa ngezindlela ezihlukahlukene. Indlela evamile ukuthola umkhiqizo ohlosiwe nge-ammonolysis ye-thioacetylacetone elandelwa yi-cyclization. Ngaphezu kwalokho, kunezinye izindlela zokuhlanganisa, ezifana ne-nitroation ye-carbon compounds, ukunciphisa i-acyl oxime, njll.
Ulwazi Lokuphepha:
I-2,5-Dimethylpyrazine iphephile uma kuqhathaniswa nabantu kanye nemvelo ngaphansi kwezimo ezijwayelekile zokusetshenziswa
- Uma uthinta isikhumba namehlo, kungase kubangele ukucasuka nokuvuvukala, futhi kufanele kuthathwe izinyathelo zokuqapha lapho uyisebenzisa, njengokugqoka amagilavu okuzivikela kanye nezibuko.
- Gwema ukuhogela amagesi noma uthuli ngesikhathi ubamba, njengoba ukuhogela isikhathi eside kungase kubangele ukucasuka kokuphefumula.
- Ukuthintana nama-oxidants nama-asidi aqinile kufanele kugwenywe lapho ugcina ukugwema ukusabela okuyingozi.
- Uma uyilahla, yilahle ngokuhambisana nemithethonqubo efanele futhi ugweme ukukhishelwa ngokuqondile endaweni ezungezile.
