Methyl Phenylglyoxalate Ma Cas 15206-55-0
Benzoic acid ma le methanol e maua mai esterification. O le methanol cyclic ma le benzoylformic acid sa fa'aopoopo i le ulo tali, ma fa'aopoopo lemu le sulfuric acid i le fa'aosoina. Ina ua uma ona faʻamafanafanaina i lalo ole reflux mo le 12 itula, na toe maua mai le methanol sili atu. O le oloa esterified sa neutralized i dilute sodium carbonate solution, o le suauʻu vaega na vavae ese, ma le aqueous layer na aveese mai i le benzene. O le su'ega sa tu'u fa'atasi ma le fa'apala o le suau'u, fa'amago i luga o le sodium sulfate, ma fa'amama. Muamua, na toe maua mai le benzene solvent, ona faʻafefe ai lea o pusa maualalo i lalo o le faʻaitiitia o le mamafa. Ona aoina lea o vaega ninii ma ave o le methyl benzoylformate.

Methyl benzoylformate ose mea fa'avatuva mo le herbicide mezatrione. Mo le fa'apipi'i fa'aola ma fa'alavalava ma vaitusi e mafai ona togafitia i le UV.
