| Abstract: | Methy 1,3 oxathiolane and 2 propyl 1,3 oxathiolane were synthesized by the reaction of mercaptoethanol with acetaldehyde or butyraldehyde in the presence of p toluenesulfonic acid as catalyst and with benzene as azeotropic dehydrating agent.The yields were 81% and 88% and the purity were 99% and 98% respectively.Structures of the compounds were identified by the data of IR,GC-MS and 1HNMR spectra.The synthesis scheme was convenient and high yields were available. |
