phthalates are esters of ortho-phthalic acid. these compounds have applications in many industrial sectors. they are used as plasticizers to improve flexibility of plastics such as polyvinyl chloride (pvc) in which they can represent up to 40% of the total mass [1]..

biodegradable pvc plasticizer derived from a new co2-based poly,hence, there is an urgent need to develop non-toxic, highly efficient and migration resistant plasticizers, especially given the predicted growth in plasticizer demand. various bio-based resources such as vegetable oil [13], [14], critic acid [15], [16], vanillic acid [10], [17], woody oil [18], soybean oil [19], castor oil [20], glycerol and adipic acid [21], [22] and so forth have been.
