Los ntawm qhov kev xav ntawm keeb kwm kev loj hlob ntawm Tuam Tshoj txoj kev lag luam tshuaj intermediates, tom qab yuav luag 30 xyoo ntawm kev txhim kho, cov tshuaj intermediates tau tsim los ntawm ib ceg me me ntawm kev lag luam tshuaj mus rau hauv kev lag luam tshiab nrog cov nqi tsim tawm ntawm billions ntawm yuan, thiab nws cov kev sib tw ua lag luam tau dhau los ua qhov hnyav dua.

Nws to taub tias nyob rau theem pib ntawm kev txhim kho kev lag luam tshuaj intermediates, vim yog kev nqis peev me me thiab tus nqi rov qab siab, cov tuam txhab tshuaj intermediates tau loj hlob zoo li nceb, tshwj xeeb tshaj yog hauv Zhejiang, Taizhou, Nanjing thiab lwm thaj chaw uas muaj cov xwm txheej zoo rau kev txhim kho kev lag luam tshuaj intermediates, kev txhim kho sai heev.

Tam sim no, vim tias kev hloov pauv ntawm cov qauv kev lag luam kho mob, nrog rau kev tsim cov tshuaj tshiab hauv kev ua lag luam raug txwv, qhov nyuaj ntawm kev tsim cov khoom lag luam tshuaj intermediates tshiab yog qhov loj dua thiab ntau dua, cov khoom ib txwm muaj kev sib tw ntau dua thiab ntau dua, cov txiaj ntsig ntawm kev lag luam tshuaj intermediates poob qis sai, thiab cov tshuaj intermediates ua rau muaj teeb meem ntawm kev txhim kho ntawm lub tuam txhab.

Kev lag luam ntseeg tias nws yuav ua tau los tsim nws tus kheej qhov kom zoo dua los ntawm cov yam ntxwv ntawm thev naus laus zis, kev cuam tshuam thiab kev hloov pauv, kom sawv tawm hauv kev ua lag luam.

Hais txog thev naus laus zis, nws feem ntau yog hais txog kev txhim kho thev naus laus zis thiab txuag nqi. Nws tau tshaj tawm tias txoj kev ua haujlwm ntawm cov tshuaj nruab nrab yog ntev, cov kauj ruam ua tshuaj yog ntau, kev siv cov kuab tshuaj yog loj, thiab kev txhim kho kev siv tshuab yog loj.

Piv txwv li, cov khoom siv raw uas tsis tshua muaj nqis yuav raug siv hloov cov khoom siv raw uas muaj nqis dua, xws li kua bromide hauv kev tsim cov aminothioamidic acid thiab ammonium thiocyanate hauv kev tsim khoom es tsis txhob siv potassium thiocyanate (sodium).

Tsis tas li ntawd xwb, ib qho tshuaj yaj tuaj yeem siv los hloov cov tshuaj yaj sib txawv hauv cov txheej txheem tshuaj tiv thaiv, thiab cov cawv uas tsim los ntawm kev hydrolysis ntawm cov khoom ester tuaj yeem rov qab tau.

Hais txog kev cuam tshuam, nws feem ntau tsim nws cov khoom lag luam thiab txhim kho nws cov kev cuam tshuam hauv kev lag luam. Nws nkag siab tias vim yog kev sib tw ua kom muaj kev sib xyaw ua ke ntawm cov khoom lag luam hauv Suav teb kev lag luam tshuaj, yog tias cov tuam txhab tuaj yeem tsim lawv cov khoom lag luam zoo, lawv yuav muaj ntau qhov zoo dua hauv kev ua lag luam.

Hais txog kev hloov pauv, tam sim no, nrog rau kev cai tiv thaiv ib puag ncig nruj dua hauv Suav teb, cov peev txheej nyiam mus rau cov lag luam muaj nqis ntxiv, thiab nrog rau kev nce ntxiv ntawm cov nqi tiv thaiv ib puag ncig, kev hloov pauv tau dhau los ua teeb meem uas yuav tsum tau xav txog rau kev txhim kho kev lag luam tshuaj intermediates.

Nws raug pom zoo tias cov tuam txhab tshuaj nruab nrab yuav tsum nthuav dav cov saw hlau kev lag luam mus rau sab saud thiab sab hauv qab, thiab tig cov khoom siv tseem ceeb uas lawv siv rau hauv lawv cov khoom tsim tawm. Ua li no, tus nqi tuaj yeem txo qis ntxiv, thiab rau qee cov khoom siv tshwj xeeb, kev tswj hwm cov khoom siv tseem ceeb tuaj yeem zam tau.

Kev lag luam hais tias qhov kev poob qis, uas cov tshuaj intermediates raug tsim ncaj qha rau hauv apis, tuaj yeem ua rau cov khoom muaj nqis ntxiv thaum muag ncaj qha rau cov tuam txhab tshuaj. Nws tsim nyog sau tseg tias muaj kev nqis peev loj hauv kev nthuav dav downstream, nrog rau qhov xav tau siab rau cov thev naus laus zis tsim khoom thiab kev sib raug zoo nrog cov neeg siv API. Feem ntau, cov tuam txhab ua lag luam yuav tau txais txiaj ntsig ntau dua.

Tsis tas li ntawd xwb, KEV TSHAWB FAWB thiab kev txhim kho tseem ceeb heev rau kev lag luam theem nrab. Tam sim no, kev lag luam tshuaj theem nrab hauv Suav teb feem ntau tsis tshua muaj kev saib xyuas rau kev tshawb fawb thiab kev txhim kho. Yog li ntawd, nyob rau hauv cov ntsiab lus ntawm kev txhim kho tas li ntawm cov kev cai lij choj, cov tuam txhab R & D zoo nrog lub zog R & D muaj zog yuav los ua ntej, thaum cov lag luam me thiab nruab nrab uas tsis muaj peev xwm R & D yuav raug tshem tawm los ntawm kev ua lag luam. Yav tom ntej, kev sib sau ua ke ntawm kev lag luam yuav raug txhim kho ntxiv thiab theem nruab nrab thiab qis kawg yuav raug txhim kho mus rau theem siab dua.
