Ukuthuthuka Okuyinhloko
Ngomhlaka-28 Okthoba, ubuchwepheshe bokususa i-aromatic functionalization obuqondiswe ngqo kuma-aromatic amines bathuthukiswa yithimba likaZhang Xiaheng elivela e-Hangzhou Institute for Advanced Study, University of Chinese Academy of Sciences (HIAS, UCAS) banyatheliswa kuyi-Nature. Lobu buchwepheshe buxazulula izinselele zokuphepha nezindleko eziye zahlupha imboni yamakhemikhali iminyaka engu-140.
Okuvelele Kobuchwepheshe
1. Ushiya inqubo yendabuko kasawoti we-diazonium (evame ukuqhuma kanye nokungcola okukhulu), efinyelela ukuguqulwa kwesibopho se-CN okuphumelelayo ngokusebenzisa ama-intermediate e-N-nitroamine.
2. Ayidingi ama-catalyst ensimbi, inciphisa izindleko zokukhiqiza ngo-40%-50%, futhi isiqedile ukuqinisekiswa kwesisindo samakhilogramu.
3. Isebenza cishe kuzo zonke izinhlobo zama-amine e-heteroaromatic kanye ne-aniline derivatives, ngaphandle kokuvinjelwa yisikhundla seqembu lama-amino.
Umthelela Wezimboni
1. Imboni yemithi: Njengomgogodla oyinhloko wama-70% emithi yama-molecule amancane, ukuhlanganiswa kwemithi elwa nomdlavuza kanye nemithi yokucindezeleka kuba okuphephile futhi okonga kakhulu. Amabhizinisi afana neBaicheng Pharmaceutical kulindeleke ukuthi abone ukwehliswa kwezindleko ngo-40%-50%.
2. Imboni ye-Dyestuff: Amabhizinisi ahamba phambili njengeZhejiang Longsheng, aphethe isabelo semakethe esingu-25% kuma-aromatic amine, axazulula ingozi yokuqhuma eye yanciphisa isikhathi eside ukwanda kwamandla.
3. Imboni yezibulala-zinambuzane: Amabhizinisi afaka phakathi iYangnong Chemical azobhekana nokwehla okukhulu kwezindleko zezibulala-zinambuzane.
4. Izinto ze-elekthronikhi: Ikhuthaza ukuhlanganiswa okuluhlaza kwezinto ezikhethekile ezisebenzayo.
Ukusabela Kwemakethe Yezimali
Ngomhlaka-3 Novemba, umkhakha wamakhemikhali waqina ngokumelene nomkhuba wemakethe, kanti ingxenye ye-aromatic amine ihola phambili ekuzuzeni kanye namasheya omqondo ahlobene nawo abonisa amandla aphelele.
Isikhathi sokuthunyelwe: Novemba-06-2025
