Kev Tswj Xyuas Cov Tshuaj Tiv Thaiv Maleic Anhydride
Maleic anhydride yog tsim los ntawm kev ua oxidation reactions, nrog rau cov xwm txheej tseem ceeb xws li kub, sijhawm, thiab siab. Cov yam ntxwv ib txwm muaj yog: kub ntawm 170–220°C, lub sijhawm ua teb ntawm 2–6 teev, thiab siab ntawm 1–3 MPa. Cov yam ntxwv no yuav tsum tau kho raws li cov khoom catalyst, cov yam ntxwv ntawm cov khoom siv raw, thiab cov lus qhia ntawm cov khoom.
Kev Tswj Xyuas Kev Ua Haujlwm ntawm Maleic Anhydride Esterification
Esterification yog ib kauj ruam tseem ceeb hauv kev tsim khoom. Nws yuav tsum tau sib xyaw tag nrho cov khoom siv raw, nrog rau qhov kub thiab txias, lub sijhawm, thiab lub siab kom raug. Thaum lub sijhawm ua tshuaj, pH thiab cov dej noo yuav tsum tau saib xyuas thiab tswj kom ntseeg tau tias kev ua tshuaj thiab cov khoom zoo.
