ʻO 2,8-Diazabicyclo[4.3.0]nonane, i kapa ʻia ʻo DBN, he mea hoʻohui kemika me kahi hoʻolālā kū hoʻokahi e hāʻawi iā ia i kahi ākea o nā noi ma nā ʻano āpau. a me ka mea hoʻoikaika.Hāʻawi kona ʻano bicyclic i ke kūpaʻa, hiki ke hoʻohana ʻia i nā ʻano like ʻole.Hoʻohana nui ʻia ka DBN i nā hoʻololi kūlohelohe kahi e koi ʻia ai kahi kumu ikaika, e like me ka deprotonation o nā pūhui waikawa a i ʻole ka hana ʻana i nā paʻa carbon-nitrogen.Hiki ke hoʻohana ʻia i ka synthesis o nā lāʻau lapaʻau, agrochemicals, a me nā molekala organik paʻakikī. Hoʻohana pū ʻia ʻo DBN ma ke ʻano he mea hoʻohui i ka kemika polymer.ʻO kona ʻano kumu e hiki ai ke hana ma ke ʻano he neutralizing agent i ka hana ʻana o polyurethane foams a me nā elastomers.Kōkua ia i ka mālama ʻana i nā kinetics hopena a hoʻonui i nā waiwai kino o ka polymer hopena, e like me ka ikaika mechanical a me ka pale wela.Eia kekahi, hiki ke hoʻohana ʻia ʻo DBN ma ke ʻano he lāʻau lapaʻau no nā resins epoxy, e hāʻawi ana i kā lākou cross-linking a me nā kaʻina polymerization.Hiki ke hoʻohana ʻia ma ke ʻano he reactive intermediate i ka synthesis o nā lāʻau lapaʻau, ʻoi loa no ka hoʻomākaukau ʻana i nā pūhui heterocyclic.ʻO kāna mea maʻamau e hiki ai ke hoʻokumu i nā kikowaena koʻikoʻi a i ʻole ka hoʻololi ʻana o nā molekala lāʻau e hoʻonui ai i kā lākou hana pharmacological a waiwai paha.Hana pū ʻo DBN ma ke ʻano he catalyst i kekahi mau lāʻau lapaʻau, e like me ka deprotection koho o nā pūʻulu pale a i ʻole ka hoʻokumu ʻana i nā peptide bonds. Ua hōʻike ʻo DBN i kahi catalyst kūpono a versatile i ka synthesis organik asymmetric pū kekahi.ʻO kona ʻano kūʻokoʻa a me kona ʻano kumu e hiki ai iā ia ke catalyze i nā hopena enantioselective like ʻole, e hoʻomaʻamaʻa i ka hana ʻana o nā molekala chiral me ka stereoselectivity kiʻekiʻe a me ka pono.ʻO kēia ka mea hana waiwai no ka synthesis o nā lāʻau lapaʻau a me nā pūhui organik paʻakikī ʻē aʻe kahi e koʻikoʻi ai ka chirality.ʻO kona kumu ikaika, kūpaʻa, a me ka hoʻolālā bicyclic kūʻokoʻa e lilo ia i mea hana maʻalahi no nā ʻano like ʻole a me nā noi.Mai kona hoʻohana ʻana ma ke ʻano he catalyst a me ke kumu i ka kemika organik i kāna hana hoʻohui i nā kaʻina polymerization a me kāna mau noi i ka synthesis pharmaceutical, hāʻawi ʻo DBN i kahi ākea ākea no nā ʻepekema a me nā mea noiʻi ma nā kahua he nui.
