1,8-Diazabicyclo[5.4.0]undec-7-ene CAS:6674-22-2

He maha ngā whakamahinga o te 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) puta noa i ngā momo marautanga pūtaiao, inā koa i roto i te matū waro, te rongoā, me te pūtaiao pūmua. Ko tētahi o ōna whakamahinga matua he turanga tino whai hua i roto i ngā tauhohenga hanganga matū e uru ana ki te deprotonation, te condensation, me ngā tukanga whakakorenga. Nā te kaha o te turanga me te nucleophilicity o te DBU ka waiho hei whakakorikori whai hua mō te whakatairanga i ngā momo panonitanga me te whiriwhiringa teitei me te whai huatanga. Haunga tōna tūranga hei matū maha-whakaurunga i roto i te hanganga waro, ka whakamahia te DBU i roto i te matū rongoā me te kimi rongoā hei whakahaere i te whakarite i ngā takawaenga rongoā me ngā matū hohe. Ko tōna whai wāhi ki ngā mahi hanga matua ka taea te whakaputa i ngā ngota matatini me te kaha whakaora, ka whai wāhi ki te whanaketanga o ngā rongoā hou me ngā kaihoko rongoā mō te rongoā i ngā mate. Hei tāpiri, he wāhanga nui tēnei matū i roto i ngā tauhohenga pūmua, inā koa i roto i te whakaputanga o ngā polyurethanes me ētahi atu rauemi pūmua. Ko te kaha o DBU ki te whakatere i ngā tukanga polycondensation me te whakatairanga i te hononga whakawhiti polymer ka whakarei ake i ngā āhuatanga polymer, pērā i te kaha miihini, te pumau wera, me ngā āhuatanga piri, ka arahi ki te hanganga o ngā rauemi matatau mō ngā tono ahumahi me ngā tono arumoni. Heoi anō, e whakamahia ana a DBU i roto i ngā rangahau mātauranga hei tirotiro i ngā tauhohenga rauropi, ngā ara miihini, me ngā whanaungatanga hanganga-mahi i roto i ngā pūnaha matū. Ka tūhuratia e ngā kaipūtaiao te tauhohenga me te whiriwhiringa o DBU i roto i ngā horopaki hangai hei whakamārama i ngā tikanga tauhohenga, hei arotau i ngā āhuatanga tauhohenga, me te kimi rautaki hou mō te hanga i ngā matū me ngā rauemi whai hua. I te nuinga, he mahi nui tā te 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) i roto i te hanga rauropi, te whanaketanga rongoā, te matū polymer, me ngā mahi rangahau taketake. Ko ōna āhuatanga ahurei, ngā kaha whakatere, me te whānui o te whai huatanga ka waiho hei taputapu tino nui mō te whakatairanga i te mātauranga pūtaiao, te auahatanga hangarau, me ngā tono mahi i roto i ngā mara rerekē o te matū me te pūtaiao rauemi.
