| Abstract: | The oxidation of series of benzenedimethanols involving 1,2-benzenedimethanol,1,3-benzenedimethanol and 1,4-benzenedimethanol with IBX,has been investigated in aqueous solution to synthesize the corresponding aldehydes.The effect of reaction time on the oxidation exhibited that the oxidazing benzenedimethanols achieved equilibrium the conversion was 63%,47% and 60%,respectively,the primary products were the corresponding hydroxymethylbenzaldehydes,when the ratio of IBX to benzenedimethanols were 1:1;and that the reactions achieved when the IBX and alcohols were in the ratio of 2:1,the conversion was observed as 83%,77% and 91%,respectively.The results show that the oxidation of benzenedimethanols was carried out selectively. |
