Synthesis and Characterization of BisN-(3-rosin acyloxy-2-hydroxyl) propyt-N,N dimethylamine
An anti-fungal derivative of rosin was synthesized.First,rosin was modified by acrylic acid and the modified rosin was esterified by epoxy chloropropane with the mole ratio of 1:3 for 3.5h at 90℃.The intermediate was bis 3-rosin acyloxy-2- hydroxypropyl chlorine and the degree of esterification was 98.81％.Then,bisN-(3-rosin acyloxy-2-hydroxyl) propyl-N,N dimethylamine was made from the intermediate under the following conditions: the intermediate and dimethylamine mole ratio of 1:2,reaction temperature of 80 ℃ and reaction time of 2.5h.The chemical structure of the product was identified by Fourier transform infrared spectroscopy (FTIR).The anti-fungal activity of the product was determined by paper-disc method with wood decay fungi such as Trametes versicolor,Gloeophyllum trabeum and wood stain fungi such as Aspergillus niger and Paecilomyces variot Bainier.The anti-fungal experiment results signified that bisN-(3-rosin acyloxy-2-hydroxyl) propyl-N,N dimethylamine is active vs.these fungi,but less effective with Aspergillus niger.Since it is produced easily from rosin,which is renewable and not expensive,this product has a promising future as a potential wood preservative.
