Kev tsim ntawm Methyl Acetate

Tsim cov methyl acetate los ntawm ntau txoj kev xws li esterification, ntxiv acetic acid, thiab methanol cov tshuaj tiv thaiv, thiab lwm yam.

Ib txoj hauv kev los tsim methyl acetate yog los ntawm esterification. Nyob rau hauv cov txheej txheem no, acetic acid thiab methanol react nyob rau hauv lub xub ntiag ntawm ib tug catalyst zoo li sulfuric acid los yog hydrochloric acid los tsim cov ester. Cov tshuaj tiv thaiv tshwm sim nyob ib ncig ntawm 50-60 degree thiab yields high-zoo methyl acetate nrog ib tug purity ntawm ntau tshaj 99%.

Lwm txoj kev ntawm kev tsim methyl acetate yog qhov sib ntxiv ntawm acetic acid rau methanol. Cov txheej txheem no yog ua nyob rau hauv lub xub ntiag ntawm ib tug concentrated sulfuric acid los yog lwm yam catalysts haum. Cov sulfuric acid ua raws li lub cev qhuav dej thiab pab tshem tawm cov dej tsim thaum lub sij hawm cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv tshwm sim ntawm qhov kub ntawm li 60-70 degree thiab ua rau muaj txiaj ntsig zoo ntawm methyl acetate.

Cov tshuaj tiv thaiv ntawm methanol thiab anhydrous acetic acid kuj siv tau los tsim methyl acetate.

Tsim cov methyl acetate yog synthesized los ntawm ntau txoj kev. Cov txheej txheem no suav nrog esterification, ntxiv ntawm acetic acid, thiab cov tshuaj methanol. Cov txheej txheem no muab cov khoom zoo methyl acetate uas pom kev siv dav hauv ntau yam lag luam.
