Nyob rau hauv cov nqe lus ntawm ntau lawm technology, cov txheej txheem ntau lawm ntawm tetrachlorophthalic anhydride tau mus txog ib tug heev paub tab thiab ruaj khov theem.
Txawm li cas los xij, nrog cov nqi hluav taws xob nce ntxiv thiab nce kev ntxhov siab ib puag ncig, cov tuam txhab tau cog lus los txhim kho kev siv hluav taws xob thiab kev ua kom zoo tshaj plaws los txo cov nqi tsim khoom thiab txo qhov cuam tshuam ib puag ncig.
Tsis tas li ntawd, kev nce qib hauv catalyst thev naus laus zis tau txhim kho kev tsim khoom zoo thiab muaj peev xwm.
Saib ua ntej, kev ua lag luam tetrachlorophthalic anhydride tseem yuav tau txais txiaj ntsig los ntawm kev lag luam thoob ntiaj teb kev loj hlob thiab kev tsim khoom.
Kev loj hlob sai ntawm kev lag luam thiab kev lag luam hauv cov lag luam tawm tshiab xws li Asia thiab Middle East yuav muab kev loj hlob tshiab rau kev lag luam tetrachlorophthalic anhydride.
Nyob rau tib lub sijhawm, nrog kev nce qib thev naus laus zis tsis tu ncua thiab kev sib tw ua lag luam muaj zog, kev tsim khoom siv thev naus laus zis ntawm tetrachlorophthalic anhydride yuav txuas ntxiv tsim kho tshiab thiab txhim kho kom tau raws li kev xav tau ntawm kev lag luam rau siab -zoo, qis- cov khoom raug nqi.
