Isingeniso
I-2-Methylthio-3-methylpyrazine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
1. Ukubukeka: I-2-methylthio-3-methylpyrazine ngokuvamile iqinile emhlophe noma i-crystalline, futhi ingase ibe ifomu lempushana.
2. Ukunyibilika: Kuncibilika ezincibilikisini eziningi eziphilayo njenge-chloroform, benzene, ne-ethanol.
Sebenzisa:
1. Izibulala-zinambuzane: I-2-methylthio-3-methylpyrazine ingasetshenziswa njengezibulala-sikhunta nezibulala-zinambuzane, futhi inomphumela omuhle wokulawula isikhunta nezinambuzane kwezinye izitshalo.
2. Ikhemikhali yasolwandle: Le nhlanganisela ingasetshenziswa futhi ocwaningweni lwasolwandle ukuze kufundwe indlela yokuziphatha kanye nezimpendulo ezingokomzimba zezinto eziphilayo zasolwandle.
Indlela:
I-2-Methylthio-3-methylpyrazine ingahlanganiswa ngezinyathelo ezilandelayo:
1. Condensa i-methyl thiocyanate ne-acetone ngaphansi kwezimo ezifanele ukuze wenze ama-Kawasaki heterocycles.
Bese, i-Kawasaki heterocycle isabela nge-formic acid ukunikeza i-2-methylthio-3-methylpyrazine.
Ulwazi Lokuphepha:
1. I-2-Methylthio-3-methylpyrazine inomphumela ocasulayo futhi kufanele igwenywe ukuthintana nesikhumba namehlo.
2. Izimpahla zokuzivikela ezifanele njengamagilavu nezibuko kufanele zigqokwe lapho usebenzisa noma uphatha.
3. Uma uhogele umoya noma udliwe, funa usizo lwezokwelapha ngokushesha.
