Abstract: A biobased lipophilic β-diketone (14, 16-hentriacontanedione, Htd) was isolated from wheat straw wax. The Htd was then modified under KF/alumina mediated Michael addition reaction in a solvent less condition with methyl acrylate and dimethyl itaconate using microwave and conventional heating. Methyl acrylate formed single and double addition with the β-diketone, while the dimethyl itaconate formed only single addition. The optimal temperature for this reaction was 120 OC. The modification was also dependent on the amount of KF/alumina used and the time of reaction. The modification using microwave and traditional heating showed marginal differences, with a slight preference towards the microwave process. The recovery yield for the methyl acrylate modified β-diketone (Ma) of 60% was higher than the 20% recovery yield of dimethyl itaconate modified β-diketone (Ita). These biobased chemicals could find use as Green metals chelators and surfactants.
