Ikoranabuhanga ryo guhindura molekile ryahinduye imikorere y’ikinyejana cyashize, ikoranabuhanga ryo guhindura imiterere y’amine ihumura neza rituma habaho impinduka mu mikorere y’inganda.

Iterambere ry'ibanze

Ku ya 28 Ukwakira, ikoranabuhanga ryo gukuraho amines mu buryo butaziguye ryakozwe n'itsinda rya Zhang Xiaheng ryo mu Kigo cya Hangzhou gishinzwe Ubushakashatsi Buhanitse, Kaminuza y'Ishuri Rikuru ry'Ubumenyi bw'Abashinwa (HIAS, UCAS) ryasohotse mu kinyamakuru Nature. Iri koranabuhanga rikemura ibibazo by'umutekano n'ikiguzi byahungabanyije inganda z'imiti mu gihe cy'imyaka 140.

Ibintu by'ingenzi mu bya tekiniki

1. Yaretse uburyo gakondo bwa diazonium salt (bushobora guturika no kwanduzanya cyane), agera ku guhindura neza CN bond binyuze muri N-nitroamine intermediates.
2. Ntisaba catalysts z'ibyuma, igabanya ikiguzi cyo gukora ho 40%-50%, kandi yarangije kugenzura ibiro.
3. Ikoreshwa hafi ya amine zose zikomoka ku miti zikomoka kuri heteroaromatic na aniline, idashingiye ku mwanya w'itsinda ry'amine.

Ingaruka ku nganda

1. Inganda zikora imiti: Nk’umuti w’ingenzi wa 70% by’imiti mito ikoreshwa mu kuvura kanseri n’imiti igabanya ubukana bw’indwara zo mu mutwe, gukora imiti igabanya ubukana bw’imiti irwanya kanseri n’imiti igabanya ubukana birushaho kuba byiza kandi bihendutse. Ibigo nka Baicheng Pharmaceutical byitezwe ko bizagabanya ikiguzi cyabyo ku kigero cya 40%-50%.
2. Inganda zikora ibijyanye no gukaraba: Ibigo bikomeye nka Zhejiang Longsheng, bifite isoko rya 25% mu bintu bihumura neza, bikemura ibyago byo guturika byamaze igihe kinini bigabanya ubushobozi bwo kwagura.
3. Inganda zikora imiti yica udukoko: Ibigo birimo na Yangnong Chemical bizagabanuka cyane ku giciro cy’imiti yica udukoko.
4. Ibikoresho by'ikoranabuhanga: Biteza imbere ikorwa ry'ibikoresho byihariye bikora neza.

Inyito ku Isoko ry'Imari

Ku ya 3 Ugushyingo, urwego rw'ibinyabutabire rwakomeje kwiyongera ugereranyije n'icyerekezo cy'isoko, aho igice cya amine kigize icya mbere mu kunguka no mu bicuruzwa bifitanye isano byagaragaje imbaraga zose.
