Cov Qauv Kev Loj Hlob ntawm Maleic Anhydride
IV. Maleic Anhydride Cov Qauv Kev Loj Hlob
Hauv Suav teb, cov khoom noj benzene muaj ntau nrog kev tswj hwm kev muab khoom yooj ywm, thiab cov thev naus laus zis hauv tsev rau 10,000-ton-scale benzene oxidation-based maleic anhydride ntau lawm tau paub tab. Yog li, cov lus qhia tshiab tshaj plaws yog raws li nram no:
Ntawm ib sab tes, tsom mus rau kev ua kom zoo dua thiab txhim kho cov txheej txheem oxidation benzene kom txo qis kev siv thiab kev ua qias tuaj, yog li txhim kho kev sib tw.
Ntawm qhov tod tes, nce kev siv zog R & D rau cov khoom lag luam ntawm maleic anhydride. Piv txwv li, qhov kev thov rau cov khoom lag luam xws li polybutylene terephthalate (PBT) (cov khoom lag luam ntawm 1,4-butanediol, BDO) thiab polytetramethylene ether glycol (PTMEG) (cov khoom lag luam ntawm tetrahydrofuran, THF) tab tom loj hlob sai. Kev ua lag luam hauv tsev muaj qhov sib txawv loj, thiab cov khoom no feem ntau vam khom kev xa khoom tuaj.
