CAS 93-02-7 2, 5- dimethoxybenzaldehyde

1.InRoduction

Feem ntau, 2, 5- dimethoxybenzaldehdehdehde yog suav nrog oxidation thiab cov ntxhiab hloov hloov. Xaiv cov khoom pib tsim nyog pib, xws li 1, {{} txaus} dimethebzene, yog thawj kauj ruam hauv synthesis. Qhov no compound-hack tsim cov tshuaj tiv thaiv nyob rau hauv uas aldehyde pawg tau qhia nyob rau ntawm qhov chaw xav tau siv phosphorus oxychloride (pocl3) thiab dimethylformamide (DMF). 2, {{{{8} dimethoxybenzaldehyde yog li ntawd ua los ntawm hydrolying lub inustant nruab nrab. Raws li lwm txoj kev xaiv, 2, {10}} dimethefeastoluene tuaj yeem ua ncaj qha rau cov poov tshuaj permanganate lossis chromium trioxide. Qhov muaj ntawm cov reagents, cov lus tawm los, thiab cov nplai ntau lawm txhua yam cuam tshuam cov qauv xaiv. Txhawm rau kom tau txais cov khoom siv zaum kawg ntawm cov khoom kawg, txoj kev ua kom huv si xws li kem chromatography lossis recrystallization yog xav tau. Txhawm rau kom ua tiav cov txiaj ntsig zoo tshaj plaws, cov synthesis tsim nyog ua tib zoo saib xyuas kev siv cov reagents thiab tswj cov tshuaj tiv thaiv.
