| Abstract: | Furanones are widely used in food and tobacco,ant it is very important to study their synthesis and properties. In this paper,pure 5 methyl 3 ethyl 4, 5 dihydro 2 (3H) furanone is obtained by the reaction of the butyric acid with 1,2 epoxypropane in the presence of lithium,naphthalene and disthylamine.It is characterized by IR, 13 CNMR and GC/MS. |
