| Abstract: | bmim ] PTSA ionic liquid was prepared under microwave irradiation and to synthetic n - amyl acetate with it as catalyst. The different reaction condition influencing on the eserification were discussed. The results showed that the ionic liquid is good solvent and acetate of the reaction. The optimized condition are follow： bmim] PTSA is l SmL, the mole ratio of alcohol to acid is 1.2： 1.0, the reaction time is 1.5h . The esterification yield is 96.7%. The ionic liquid could be isolated from other matters and repetition use. |
| Keywords: | ionic liquid catalyst synthesis n - amyl acetate |
