Cov tshuaj intermediates xa mus rau qee cov khoom siv tshuaj lom neeg lossis cov khoom siv tshuaj siv hauv cov txheej txheem tsim tshuaj.
Raws li kev lag luam, kev lag luam tshuaj intermediates, ua ib qho tseem ceeb ntawm kev lag luam tshuaj zoo, yuav muaj qhov chaw loj hlob yav tom ntej.

Los 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 kev sib tw ua lag luam tau dhau los ua qhov hnyav zuj zus.

Nws to taub tias thaum ntxov 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 loj hlob zoo li xyoob tom qab los nag, tshwj xeeb tshaj yog hauv Zhejiang, Taizhou, Nanjing thiab lwm thaj chaw uas muaj cov xwm txheej zoo rau kev txhim kho 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 cov txiaj ntsig sib tw los ntawm cov yam ntxwv ntawm thev naus laus zis, kev cuam tshuam, kev hloov pauv thiab lwm yam, 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 cov nqi.
Muaj kev tshaj tawm tias cov tshuaj intermediates muaj txoj kev ua haujlwm ntev, ntau kauj ruam ua rau muaj kev cuam tshuam, muaj cov kuab tshuaj ntau, thiab muaj peev xwm zoo rau kev txhim kho txuj ci.

Piv txwv li, cov khoom siv raw uas muaj nqis qis dua tuaj yeem siv hloov cov khoom siv raw uas muaj nqis siab dua, xws li hloov bromine hauv kev tsim cov kua qaub aminotaxime, ammonium thiocyanate hloov potassium thiocyanate (sodium) hauv kev tsim khoom, thiab lwm yam.

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

Hauv qhov cuam tshuam ntawm kev cuam tshuam, nws yog qhov tseem ceeb los tsim nws cov khoom lag luam thiab txhim kho kev cuam tshuam hauv kev lag luam.
Nws to taub tias vim yog Tuam Tshoj txoj kev lag luam tshuaj intermediates, kev sib tw homogenization ntawm cov khoom yog qhov loj heev, yog tias lub tuam txhab tuaj yeem tsim lawv cov khoom zoo tshaj plaws, yuav muaj peev xwm nyob hauv kev ua lag luam ntau dua.

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

Nws raug pom zoo tias cov tuam txhab tshuaj nruab nrab txuas ntxiv cov saw hlau kev lag luam mus rau sab saud thiab sab hauv qab, thiab hloov cov khoom siv raw tseem ceeb uas lawv siv rau lawv tus kheej cov khoom tsim tawm, uas tuaj yeem txo tus nqi ntxiv. Lub caij no, rau qee cov khoom siv raw tshwj xeeb, nws tuaj yeem zam kev monopoly ntawm cov khoom siv raw tseem ceeb.

Cov kev lag luam hais tias kev txav mus rau txoj kev, qhov twg cov tshuaj intermediates raug koom ua ke ncaj qha rau hauv APIs, tuaj yeem ua rau muaj txiaj ntsig ntxiv ntawm cov khoom thaum muag ncaj qha rau cov tuam txhab tshuaj.
Nws yog ib qho tsim nyog sau tseg tias kev nqis peev hauv qab no loj dua, thaum cov kev xav tau ntawm cov thev naus laus zis ntau dua, thiab nws yog qhov tsim nyog los tswj kev sib raug zoo nrog cov chaw tsim khoom uas siv API.
Feem ntau, cov tuam txhab ua lag luam loj 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 nruab nrab. Tam sim no, kev lag luam tshuaj nruab nrab hauv Suav teb feem ntau tsis quav ntsej txog kev tshawb fawb thiab kev txhim kho.
Yog li ntawd, nyob rau hauv ib puag ncig ntawm kev txhim kho tas li ntawm cov kev cai lij choj, cov lag luam 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 nce ntxiv, thiab theem nruab nrab thiab qis kawg yuav txhim kho mus rau theem siab dua.
