Ka hurihia e te hangarau whakatika ngota te tukanga tawhito o te rautau, ka whakaoho te hangarau tango matū tika o te amine kakara i te huringa mekameka ahumahi

Te Pakaritanga Matua

I te 28 o Oketopa, i whakaputaina te hangarau whakakorenga tika mō ngā amine kakara i whakawhanakehia e te tīma a Zhang Xiaheng mai i te Hangzhou Institute for Advanced Study, University of Chinese Academy of Sciences (HIAS, UCAS) ki roto i te Nature. Ka whakatauhia e tēnei hangarau ngā wero haumaru me te utu kua pā ki te umanga matū mō ngā tau 140.

Ngā Wāhanga Hangarau

1. Ka whakarērea te tukanga tote diazonium tuku iho (he ngāwari ki te pahū me te parahanga nui), ka tutuki ai te huringa hononga CN whai hua mā roto i ngā takawaenga N-nitroamine.
2. Kāore e hiahiatia he whakakōkī whakarewa, ka whakaitihia ngā utu whakaputa mā te 40%-50%, ā, kua oti te manatoko i te tauine kirokaramu.
3. E tika ana mō te nuinga o ngā amine heteroaromatic rongoā me ngā pānga aniline, me te kore e herea e te tūranga o te rōpū amino.

Pānga Ahumahi

1. Ahumahi rongoā: Hei anga matua mō te 70% o ngā rongoā ngota iti, ka noho haumaru ake, ka whai hua ake hoki te hanga o ngā takawaenga mō ngā rongoā ārai matepukupuku me ngā rongoā ārai pouri. E matapaetia ana ka kite ngā umanga pēnei i a Baicheng Pharmaceutical i te whakahekenga utu 40%-50%.
2. Ahumahi tae: Ko ngā umanga matua pēnei i a Zhejiang Longsheng, e pupuri ana i te 25% o te hea mākete i roto i ngā amine kakara, e whakatau ana i te mōrearea pahūtanga kua roa nei e aukati ana i te whakawhānui i te kaha.
3. Ahumahi patu pepeke: Ka pāngia ngā umanga tae atu ki a Yangnong Chemical e te whakahekenga nui o te utu o ngā takawaenga patu pepeke.
4. Rauemi hiko: Ka whakatairanga i te hanganga matomato o ngā rauemi mahi motuhake.

Te Tauhohenga o te Mākete Pūtea

I te 3 o Noema, i kaha ake te rāngai matū i te taha o te ia o te mākete, ko te wāhanga amine kakara te mea e arahi ana i ngā pikinga, ā, e whakaatu ana ngā hea ariā e pā ana i te tino ora.
