A na-enweta asịd Benzoic na methanol site na esterification. A na-etinye methanol cyclic na benzoylformic acid n'ime ite mmeghachi omume ahụ, a na-agbakwụnyekwa sulfuric acid nwayọ nwayọ ka ọ na-akpali. Mgbe a kpochara ya ọkụ n'okpuru reflux ruo awa 12, eweghachiri methanol gabigara ókè. A na-ewepụ ngwaahịa esterified ahụ site na ngwọta sodium carbonate a gwakọtara agwakọta, kewapụ oyi akwa mmanụ ahụ, ma jiri benzene wepụta oyi akwa mmiri ahụ. A na-ejikọta ihe ewepụtara ahụ na oyi akwa mmanụ ahụ, kpọọ nkụ n'elu sodium sulfate anhydrous, wee gwakọta ya. Nke mbụ, a na-enweta benzene solvent, wee gbazee ya n'okpuru nrụgide dị ala. Mgbe ahụ, a na-anakọta akụkụ ndị ahụ ma were ha dị ka methyl benzoylformate.
