Isingeniso
I-5-Methyl-6,7-dihydro-5H-cyclopentapyrazine. Kuyikristalu eqinile emhlophe efana nekristalu noma impushana ngokubukeka. I-substance izinzile ekamelweni lokushisa, kodwa kancane kancane ibola ngaphansi kwesenzo sokushisa okuphezulu, ukukhanya noma umoya-mpilo.
I-5-Methyl-6,7-dihydro-5H-cyclopentapyrazine inezinhlobonhlobo zezicelo. Kuyisibulala-zinambuzane esisebenzayo esisetshenziswa kwezolimo ukulawula ukukhula nokukhiqizwa kwezinambuzane.
Kunezindlela ezimbili eziyinhloko zokulungiselela i-5-methyl-6,7-dihydro-5H-cyclopentapyrazine. Enye itholakala ngokusabela kwe-condensation ye-N-methylpyrazine, bese kuba ukusabela kwe-hydrogenation kuyenziwa ukuze kutholwe umkhiqizo ohlosiwe. Enye ihlanganiswe ukusabela kwe-oxidation nokunciphisa kwe-5-benzoyl-6,7-dihydro-5H-cyclopentapyrazine.
Ulwazi Lokuphepha: I-5-Methyl-6,7-dihydro-5H-cyclopentapyrazine iwubuthi. Kungase kube nomthelela ocasulayo ohlelweni lwezinzwa nokuphefumula komzimba futhi kucasule isikhumba namehlo. Izinyathelo ezifanele zokuzivikela ezinjengokugqoka izingubo zamehlo ezivikelayo, amagilavu nezihlangu zobuso ziyadingeka ngesikhathi sokusebenza. I-substance idinga ukugcinwa esitsheni esingangeni moya, kude nokuvutha kanye nama-oxidants. Lapho uphatha into, uthuli nama-aerosols kufanele kugwenywe, futhi ukuhogela nokuthinta isikhumba kufanele kugwenywe. Uma ukuchayeka kwenzeka, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezempilo. Lapho uphatha futhi usebenzisa i-5-methyl-6,7-dihydro-5H-cyclopentapyrazine, landela ngokucophelela izimiso zokuphepha ezifanele.
