Abstract
Hexyl propionate was synthesized from propionic acid and hexyl using tungstosilicic acid as catalyst.The influence factors such as molar ratio of hexyl alcohol to propionic acid,amount of catalyst, and reaction time on the yield of hexyl propionate were discussed.The results showed that tungstosilicic acid was a good catalyst for synthesizing hexyl propionate.The yield of hexyl propionate was up to 99.2% when molar ratio of hexyl alcohol to propionic acid was 1.5:1,amount of catalyst was 0.2 g/0.1 mol propionic acid,water-taking reagent (cyciohexane)10ml,reaction temperature was 110-118℃,and reaction time was 1 h.
