Intshayelelo
I-5-Methylquinoxaline i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-5-methylquinoxaline:
Umgangatho:
- Isakhiwo se-molecular ye-5-methylquinoxaline iqukethe ii-athomu ze-oksijini kunye nesakhiwo se-cyclic, kwaye i-compound ibonisa ukuzinza okulungileyo kwe-thermal.
- I-5-Methylquinoxaline izinzile emoyeni kwaye inokugcinwa ngokuzinzileyo kwiqondo lokushisa.
Sebenzisa:
- Inokusetyenziswa kwakhona njenge-ligand kwaye ithathe inxaxheba kwiimpendulo ze-catalytic ezifana nokuqulunqwa kwee-complex coordination.
Indlela:
- Enye yeendlela ezisetyenziswa ngokuqhelekileyo kwi-laboratory kukufumana i-5-methylquinoxaline nge-methylation. Ukusabela kunokwenziwa kusetyenziswa i-methylation reagents (umzekelo, i-methyl iodide) kunye neemeko ezisisiseko (umz., i-sodium carbonate).
Ulwazi ngoKhuseleko:
- I-5-Methylquinoxaline ayinayo ityhefu encinci, kodwa isafuna ukuphathwa ngokukhuselekileyo.
- Ngexesha lenkqubo, ukudibanisa nolusu, amehlo, kunye nokuphefumula kufuneka kugwenywe ukuphepha ukucaphuka okanye ukulimala.
- Xa ugcina kwaye uphatha i-5-methylquinoxaline, imimiselo kunye nemilinganiselo malunga neekhemikhali kufuneka ilandelwe ukuqinisekisa ukugcinwa nokuphathwa ngokukhuselekileyo.
