Uphuhliso oluPhambili
Ngomhla wama-28 kuOkthobha, iteknoloji yokusebenza kwe-aromatic amines ethe ngqo yaphuhliswa liqela likaZhang Xiaheng elivela kwiHangzhou Institute for Advanced Study, kwiYunivesithi yaseChinese Academy of Sciences (HIAS, UCAS) yapapashwa kwiNature. Le teknoloji isombulula imingeni yokhuseleko kunye neendleko ebezijongene neshishini leekhemikhali kangangeminyaka eli-140.
Iimbalasane zobugcisa
1. Bayeka inkqubo yesiqhelo yetyuwa ye-diazonium (enokugqabhuka kakhulu kunye nongcoliseko oluphezulu), bafumana ukuguqulwa kwebhondi ye-CN okusebenzayo ngokusebenzisa ii-intermediates ze-N-nitroamine.
2. Ayifuni zi-catalysts zesinyithi, inciphisa iindleko zemveliso nge-40%-50%, kwaye igqibile ukuqinisekiswa kwesikali seekhilogram.
3. Isebenza phantse kuzo zonke ii-amines ze-heteroaromatic zamayeza kunye ne-aniline derivatives, ngaphandle kokuthintelwa yindawo yeqela le-amino.
Impembelelo yoShishino
1. Ishishini lezonyango: Njengesiseko esiphambili se-70% yamayeza amancinci e-molecule, ukuhlanganiswa kwezinto ezisetyenziswa phakathi kwamayeza okulwa nomhlaza kunye ne-antidepressants kuba kukhuselekile kwaye kungabizi kakhulu. Amashishini afana neBaicheng Pharmaceutical kulindeleke ukuba abone ukwehla kweendleko nge-40%-50%.
2. Ishishini leDyestuff: Amashishini aphambili afana neZhejiang Longsheng, anesabelo semarike se-25% kwi-aromatic amines, asombulula umngcipheko wokuqhuma oye wanciphisa amandla okwandisa ixesha elide.
3. Ishishini lezibulali-zinambuzane: Amashishini aquka iYangnong Chemical aza kufumana ukwehla okukhulu kwixabiso lezibulali-zinambuzane.
4. Izixhobo ze-elektroniki: Zikhuthaza ukuhlanganiswa okuluhlaza kwezinto ezikhethekileyo ezisebenzayo.
Impendulo yeMarike yeNkunzi
Ngomhla wesi-3 kweyeNkanga, icandelo leekhemikhali laqina ngokuchasene nomkhwa wemarike, apho icandelo le-aromatic amine likhokela iinzuzo kunye nezitokhwe ezinxulumene noko ezibonisa amandla apheleleyo.
