Cov Txheej Txheem Oxidation Maleic Anhydride Benzene yog dab tsi?

Maleic Anhydride Cov Txheej Txheem Oxidation ntawm Benzene
Cov txheej txheem Maleic Anhydride no suav nrog cov pa roj oxidation ntawm benzene vapor nrog cua (lossis oxygen) hla lub catalyst (cov khoom nquag: V₂O₅-MoO₃; kev txhawb nqa: α-Al₂O₃). Cov txheej txheem tsim khoom tseem ceeb suav nrog SD (Scientific Design, US), Alusuisle / UCB, thiab Nippon Catalytic Chemical methods. Txoj kev SD yog siv dav tshaj plaws, thaum txoj kev Alusuisle / UCB muaj kev siv benzene qis tshaj plaws thiab yog qib siab dua.

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!
