Nhanganyaya
5-Methyl-6,7-dihydro-5H-cyclopentapyrazine. Iyo chena crystalline yakasimba inofanana nekristaro kana hupfu mukutaridzika. Chinhu chacho chinogadzikana pakupisa kwekamuri, asi zvishoma nezvishoma zvinoora pasi pekuita kwekushisa kwepamusoro, chiedza kana oksijeni.
5-Methyl-6,7-dihydro-5H-cyclopentapyrazine ine zvakawanda zvekushandisa. Mushonga wezvipembenene unoshanda unoshandiswa mukurima kudzora kukura nekuberekana kwezvipembenene.
Pane nzira mbiri huru dzekugadzirira 5-methyl-6,7-dihydro-5H-cyclopentapyrazine. Imwe inowanikwa ne condensation reaction yeN-methylpyrazine, uye ipapo hydrogenation reaction inoitwa kuti iwane chinongedzo chigadzirwa. Imwe yacho inogadzirwa neiyo oxidation uye kuderedza kuita kwe5-benzoyl-6,7-dihydro-5H-cyclopentapyrazine.
Ruzivo Rwekuchengetedza: 5-Methyl-6,7-dihydro-5H-cyclopentapyrazine chinhu chine chepfu. Inogona kuva nemigumisiro inogumbura pahutano hwemuviri uye kufema uye inogumbura ganda nemaziso. Matanho akakodzera ekuzvidzivirira akadai sekupfeka maziso ekudzivirira, magurovhosi uye nhoo dzechiso anodiwa panguva yekushanda. Chinhu chinoda kuchengetwa mumudziyo usingapindi mhepo, kure nekubatidza uye neoxidants. Paunenge uchibata chinhu, guruva uye aerosols zvinofanira kudziviswa, uye inhalation uye kubata kweganda kunofanira kudziviswa. Kana kuratidzwa kukaitika, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa. Paunenge uchibata uye uchishandisa 5-methyl-6,7-dihydro-5H-cyclopentapyrazine, nyatsotevera maitiro ekuchengetedza akakodzera.
