Abstract
The 10-undecenal glycol acetal was synthesized from 10-undecenal and glycol.The synthetic conditions and application of the acetal in cigarette were experimented.The results showed that the(optimum) conditions for the acetalization were: the molar ratio of undecental to glycol was 1∶1.25,(p-toluenesulfonic) acid was used as a catalyst,hexane as a solvent and heating for 60 min at refluxing(temperature.) The highest yield of the acetal was 98.74%.The acetal was capable of imparting to cigarette a characteristic flavor of brewing sweetness,reducing smoke irritation and improving smoking quality.
