【Abstract】 Pentyl butyrate was synthesized by reaction of n butyric acid and n pentanol with sodium bisulfate as catalyst.The optimum conditions for the reaction were the followings:basing on 0 1mol n butyric acid,molar ratio of n pentanol to n butyric acid was 1 3,mass of catalyst was 1 0g,and reaction time was 1 0 hr.The yield of pentyl butyrate was up to 88 3% under these conditions.Sodium bisulfate catalyst is low cost,high active and convenient in preparation and use.更多还原
