Kupambana Kwambiri
Pa Okutobala 28, ukadaulo wochotsa mwachindunji ma amines a aromatic womwe unapangidwa ndi gulu la Zhang Xiaheng kuchokera ku Hangzhou Institute for Advanced Study, University of Chinese Academy of Sciences (HIAS, UCAS) unasindikizidwa mu Nature. Ukadaulo uwu umathetsa mavuto achitetezo ndi ndalama zomwe zakhala zikuvutitsa makampani opanga mankhwala kwa zaka 140.
Mfundo Zaukadaulo
1. Amasiya njira yachikhalidwe ya mchere wa diazonium (yomwe imakonda kuphulika komanso kuipitsidwa kwambiri), zomwe zimapangitsa kuti CN bond isinthe bwino kudzera mu N-nitroamine intermediates.
2. Sikufuna zinthu zoyambitsa zitsulo, zomwe zimachepetsa ndalama zopangira ndi 40%-50%, ndipo zatsimikizira kulemera kwa kilogalamu imodzi.
3. Imagwiritsidwa ntchito pafupifupi pa ma amine onse a heteroaromatic ndi ma aniline derivatives, popanda kuletsedwa ndi malo a gulu la amino.
Zotsatira za Mafakitale
1. Makampani opanga mankhwala: Monga gawo lofunika kwambiri la 70% ya mankhwala ang'onoang'ono, kupanga mankhwala ochepetsa khansa ndi mankhwala ochepetsa nkhawa kumakhala kotetezeka komanso kotsika mtengo. Makampani monga Baicheng Pharmaceutical akuyembekezeka kuona kuchepetsedwa kwa ndalama ndi 40%-50%.
2. Makampani opanga Dyestuff: Makampani otsogola monga Zhejiang Longsheng, omwe ali ndi gawo la msika la 25% mu aromatic amines, amathetsa chiopsezo cha kuphulika chomwe chakhala chikuchepa kwa nthawi yayitali.
3. Makampani opanga mankhwala ophera tizilombo: Makampani kuphatikizapo Yangnong Chemical adzakumana ndi kuchepa kwakukulu kwa mtengo wa mankhwala ophera tizilombo.
4. Zipangizo zamagetsi: Zimalimbikitsa kupanga zinthu zapadera zogwira ntchito zobiriwira.
Kuyankha kwa Msika Wachuma
Pa Novembala 3, gawo la mankhwala linalimba kwambiri poyerekeza ndi momwe msika ukupitira, pomwe gawo la amino acid likutsogolera phindu ndi malingaliro ofanana omwe akuwonetsa mphamvu zonse.
