Mankhwala apakatikati amatanthauza zinthu zina zopangira mankhwala kapena mankhwala omwe amagwiritsidwa ntchito popanga mankhwala.
Malinga ndi makampani, mankhwala intermediates makampani, monga gawo lofunika la makampani abwino mankhwala, adzakhala ndi chitukuko danga lalikulu m'tsogolo.

Kuchokera ku mbiri yachitukuko chamakampani opanga mankhwala aku China, patatha zaka pafupifupi 30 zachitukuko, ophatikizira azamankhwala apanga kuchokera kunthambi yaying'ono yamakampani opanga mankhwala kukhala bizinesi yomwe ikubwera yomwe ili ndi phindu la mabiliyoni a yuan, ndipo mpikisano wamsika ukukulirakulira. .
Zikumveka kuti kumayambiriro kwa chitukuko cha mankhwala intermediates makampani, chifukwa ndalama yaing'ono ndi mkulu mlingo wa kubwerera, mankhwala intermediates mabizinesi amaphuka ngati nsungwi mphukira pambuyo mvula, makamaka mu Zhejiang, Taizhou, Nanjing ndi madera ena ndi yabwino. zinthu kwa chitukuko cha mankhwala intermediates chitukuko makamaka mofulumira.
Pakalipano, monga kusintha kwa chitsanzo cha msika wachipatala, komanso kupanga mankhwala atsopano pamsika kuli kochepa, vuto la makampani opanga mankhwala opangira mankhwala atsopano ndi aakulu kwambiri, mankhwala achikhalidwe akukhala mpikisano woopsa kwambiri. , pharmaceutical intermediates makampani phindu anagwa mofulumira, ndi intermediates mankhwala kukhala ndi kuganizira vuto la mmene chitukuko cha bizinesi.
Makampaniwa amakhulupirira kuti zingakhale zotheka kupanga zopindulitsa zake zokhala ndi mpikisano kuchokera kuzinthu zamakono, chikoka, kusintha ndi zina zotero, kuti ziwonekere pamsika.
Pankhani yaukadaulo, imangotanthauza kukonza ukadaulo komanso kupulumutsa ndalama.
Akuti mankhwala apakatikati ali ndi njira yayitali, masitepe ambiri amachitira, kuchuluka kwa zosungunulira, komanso kuthekera kwakukulu kwaukadaulo.
Mwachitsanzo, zopangira zotsika mtengo zitha kugwiritsidwa ntchito m'malo mwa zopangira zamtengo wapatali, monga bromine yolowa m'malo popanga aminotaxime acid, ammonium thiocyanate m'malo mwa potassium thiocyanate (sodium) popanga, ndi zina zambiri.
Komanso, zosungunulira limodzi angagwiritsidwenso ntchito m`malo zosungunulira zosiyanasiyana mu ndondomeko anachita, ndi mowa kwaiye ndi hydrolysis wa mankhwala ester akhoza anachira.
Pankhani yachikoka, makamaka kupanga zinthu zakezake ndikuwongolera chikoka pamakampani.
Zikumveka kuti chifukwa cha makampani China mankhwala intermediates, mankhwala homogenization mpikisano ndi lalikulu, ngati ogwira ntchito angathe kulenga zinthu zawo apamwamba, adzatha kutenga ubwino zambiri msika.
Pankhani ya kusintha, pakali pano, ndi zofunikira zotetezera zachilengedwe zapakhomo zimakhala zovuta kwambiri, chuma chimakonda kwambiri mafakitale owonjezera mtengo, ndipo chifukwa cha kuwonjezeka kwa ndalama zotetezera chilengedwe, kusintha kwakhala vuto lomwe mabizinesi apakatikati a zamankhwala ayenera kuganizira. chitukuko chokhazikika.
Akuti mabizinesi apakatikati azachipatala amakulitsa unyolo wa mafakitale kumtunda ndi pansi, ndikusamutsa zida zazikulu zomwe amagwiritsa ntchito kuti apange okha, zomwe zitha kuchepetsa mtengowo. Pakadali pano, pazinthu zina zapadera zopangira, zimatha kupewa kukhazikika kwazinthu zazikulu zopangira.
Makampaniwa akunena kuti kusunthira mumsewu, kumene mankhwala opangira mankhwala amaphatikizidwa mwachindunji mu APIs, akhoza kuonjezera mtengo wowonjezera wa mankhwala pamene akugulitsa mwachindunji ku makampani opanga mankhwala.
Ndikoyenera kudziwa kuti ndalama zotsika mtengo ndizokulirapo, pomwe zofunikira zaukadaulo wopanga ndizokwera, ndipo ndikofunikira kusunga ubale wabwino ndi opanga omwe amagwiritsa ntchito API.
Pazonse, mabizinesi otsogola atha kukhala ndi mwayi wampikisano.
Kuphatikiza apo, kafukufuku ndi chitukuko ndizofunikira kwambiri pamakampani apakatikati. Pakadali pano, makampani apakatikati azachipatala ku China salabadira kwenikweni kafukufuku ndi chitukuko.
Chifukwa chake, m'malo omwe akuwongolera zofunikira zaukadaulo, mabizinesi ogwira ntchito a R&D okhala ndi mphamvu zolimba za R&D adzawonekera, pomwe mabizinesi ang'onoang'ono ndi apakatikati opanda luso la R&D atha kuthetsedwa ndi msika. M'tsogolomu, ndende yamakampani idzawonjezekanso, ndipo gawo lachitukuko lapakati ndi lotsika lidzakhala lokwera kwambiri.
