Intshayelelo
I-5-Methyl-6,7-dihydro-5H-cyclopentapyrazine. Yikristale emhlophe eqinileyo efana nekristale okanye umgubo ngenkangeleko. I-substance izinzile kwiqondo lokushisa, kodwa ngokuthe ngcembe ibola phantsi kwesenzo sokushisa okuphezulu, ukukhanya okanye i-oxygen.
I-5-Methyl-6,7-dihydro-5H-cyclopentapyrazine inoluhlu olubanzi lwezicelo. Sisibulali zinambuzane esisebenzayo esisetyenziswa kwezolimo ukulawula ukukhula nokuzala kwezinambuzane ezitshabalalisayo.
Kukho iindlela ezimbini eziphambili zokulungisa i-5-methyl-6,7-dihydro-5H-cyclopentapyrazine. Enye ifunyanwa ngokusabela kwe-condensation ye-N-methylpyrazine, kwaye emva koko i-hydrogenation reaction iyenziwa ukufumana imveliso ekujoliswe kuyo. Enye ihlanganiswe yi-oxidation kunye nokunciphisa ukusabela kwe-5-benzoyl-6,7-dihydro-5H-cyclopentapyrazine.
Ulwazi loKhuseleko: I-5-Methyl-6,7-dihydro-5H-cyclopentapyrazine yinto enobuthi. Inokuba nefuthe elicaphukisayo kumzimba kunye nenkqubo yokuphefumla kwaye iyacaphukisa ulusu kunye namehlo. Amanyathelo afanelekileyo okuzikhusela anjengokunxiba iliso elikhuselayo, iiglavu kunye nezikhuselo zobuso ziyafuneka ngexesha lokusebenza. Umxube kufuneka ugcinwe kwisikhongozeli esingangeni moya, kude nokuvutha kunye nee-oxidants. Xa uphatha i-substance, uthuli kunye ne-aerosols kufuneka zigwenywe, kwaye ukuphefumla kunye nokudibanisa kwesikhumba kufuneka kugwenywe. Ukuba ukuvezwa kuyenzeka, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango. Xa uphatha kwaye usebenzisa i-5-methyl-6,7-dihydro-5H-cyclopentapyrazine, landela ngokucophelela iiprothokholi ezifanelekileyo zokhuseleko.
