Tuam Tshoj kws tshuaj intermediates kev lag luam tau tsim nyob rau hauv 2000

Cov tshuaj hu ua intermediates yog qhov tseeb qee cov khoom siv tshuaj lom neeg lossis cov khoom siv tshuaj siv hauv cov txheej txheem ntawm cov tshuaj synthesis.Cov khoom siv tshuaj zoo li no, tsis tas yuav dhau daim ntawv tso cai tsim tshuaj, tuaj yeem ua rau hauv cov tshuaj cog qoob loo zoo tib yam, thaum mus txog qee qib, tuaj yeem siv rau hauv cov tshuaj synthesis.
Pharmaceutical intermediates yog cov txuas tseem ceeb hauv kev lag luam kws tshuaj.

Kev kho mob intermediates yog subdivided rau hauv thawj intermediates thiab advanced intermediates.Ntawm lawv, cov neeg muag khoom nruab nrab tsuas tuaj yeem muab cov khoom lag luam nruab nrab yooj yim thiab yog nyob rau pem hauv ntej ntawm cov saw hlau, qhov kev sib tw siab thiab tus nqi siab yog qhov loj tshaj.Yog li ntawd, tus nqi hloov pauv ntawm cov khoom siv tshuaj lom neeg muaj txiaj ntsig zoo rau lawv.
Ntawm qhov tod tes, cov neeg muag khoom nruab nrab qib siab tsis yog tsuas yog muaj kev sib txuas lus muaj zog tshaj cov neeg muab khoom lag luam, tab sis qhov tseem ceeb tshaj, vim tias lawv tau ua tiav cov txheej txheem nruab nrab nrog cov ntsiab lus thev naus laus zis siab dua thiab ua kom muaj kev sib cuag nrog ntau lub teb chaws, yog li lawv tsis tshua cuam tshuam los ntawm tus nqi. fluctuation ntawm raw khoom.
Midstream belongs rau kev lag luam tshuaj zoo tshuaj.Cov neeg tsim khoom ntawm cov tshuaj intermediates synthesize intermediates los yog crude apis thiab muag cov khoom nyob rau hauv daim ntawv ntawm cov khoom siv tshuaj rau cov kws lag luam, uas tom qab ntawd muag lawv li tshuaj tom qab refining.

Tuam Tshoj kws tshuaj intermediates kev lag luam tau tsim nyob rau hauv 2000.
Lub sijhawm ntawd, cov tuam txhab tshuaj hauv cov teb chaws tsim kho tau them nyiaj ntau dua rau kev tshawb fawb thiab kev tsim khoom thiab kev tsim kho kev lag luam raws li qhov tseem ceeb ntawm kev sib tw, thiab ua kom nrawm rau kev hloov pauv ntawm cov khoom nruab nrab thiab cov tshuaj nquag synthesis rau cov teb chaws uas muaj nqi qis dua.Vim li no, kev lag luam tshuaj intermediates tau txais kev txhim kho zoo heev los ntawm lub sijhawm no.Tom qab ntau tshaj kaum xyoo ntawm kev txhim kho ruaj khov, nrog kev txhawb nqa ntawm lub teb chaws tag nrho cov kev cai thiab kev tswj hwm thiab ntau yam kev cai, peb lub teb chaws tau dhau los ua ib qho tseem ceeb hauv nruab nrab ntawm kev tsim khoom hauv ntiaj teb kev faib ua haujlwm hauv kev lag luam tshuaj.

Los ntawm 2016 txog 2021, kev tsim cov tshuaj intermediates hauv Suav teb tau nce los ntawm kwv yees li 8.1 lab tons, nrog kev lag luam loj txog li 168.8 billion yuan, txog li 10.12 lab tons, nrog kev lag luam loj ntawm 2017 billion yuan.
