| Abstract: | Isopentyl lactate was synthesized from lactic acid and isopentyl alcohol in the presence of strongly acidic cationic exchange resin. The yield of the ester can reach 92% in the condition of lactic acid and isopentyl alcohol 1∶2( W/W ), strongly acidic cationic exchange resin 1.5g, refluxing and water segrating for 60min. The reuseability of the catalyst was studied. |
