Cov txheej txheem tsim tawm txawv teb chaws rau maleic anhydride yog dab tsi?

2025-12-24

Cov Txheej Txheem Synthesis Txawv Tebchaws
Kev lag luam tam sim no Maleic Anhydride Cov kev tsim khoom feem ntau yog benzene-based, n-butane-based, C4 olefin-based, thiab phthalic anhydride byproduct-based.
Benzene tau ntev los ua cov khoom siv raw rau maleic anhydride, tab sis cov peev txheej benzene tsawg tau tsav txoj kev loj hlob ntawm C4 olefin thiab n-butane. Cov teb chaws nplua nuj nyob rau hauv cov roj av thiab cov roj av cuam tshuam nrog cov chaw ua roj (uas muab ntau n-butane) tau nce qib sai sai n-butane cov txheej txheem - tam sim no suav txog ~ 80% ntawm lub peev xwm tsim khoom thoob ntiaj teb.

Vim li cas ho xaiv Maleic Anhydride? Nws yog lub hauv paus ntawm cov polyester resins tsis muaj zog zoo tshaj plaws, ntxiv rau nws qhib ntau yam tshuaj lom neeg (BDO, THF, thiab lwm yam). Xa xov rau peb tam sim no kom tshawb nrhiav cov kev daws teeb meem MA uas haum rau koj txoj kev lag luam!
