Synthesis of the Alkyl Esters of α Furoic Acid as Flavours

The seven alkyl esters of α furoic acid were synthesized in the yields of 80% to 95.6% by refluxing the solution of benzene (or toluene) containing 0.1 mole α furoic acid and corresponding aliphatic alcohols (0.12～ 0.5mole ) for 3h in the presence of p toluenesulfonic acid (0.01 mole) and 5ml hydrogen peroxide of 30%.Experimental results indicated that the yields of α furoic esters were enhanced in the above esterifications by using hydrogen peroxide and p toluenesulfonic acid as catalyst.
