Cov Txheej Txheem Tsim Khoom Maleic Anhydride Thoob Ntiaj Teb thiab Hauv Tebchaws thiab Peev Xwm

Thoob Ntiaj Teb thiab Hauv Tebchaws Maleic Anhydride Cov Txheej Txheem Tsim Khoom thiab Peev Xwm
Kev lag luam maleic anhydride thoob ntiaj teb tab tom hloov ntawm kev tsim benzene mus rau n-butane-based synthesis: n-butane cov txheej txheem tam sim no suav txog ~ 80% ntawm tag nrho cov peev xwm tsim khoom thoob ntiaj teb. Hauv Suav teb, kev thov maleic anhydride tab tom loj hlob sai, tab sis kev tsim khoom tseem vam khom rau cov txheej txheem benzene. Suav teb yuav tsum tsom mus rau kev ua kom zoo dua ntawm kev tsim khoom benzene thaum npaj rau kev hloov kho thev naus laus zis n-butane - txhim kho cov txheej txheem, tshem tawm cov chav me me, tsis muaj txiaj ntsig los txhim kho kev sib tw.
Cov Lus Tseem Ceeb: Maleic anhydride; n-butane; kev ua lag luam; kev loj hlob

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!
