Ultrasound assisted synthesis of epoxidized sunflower oil and application as plasticizer
Anand P. Chavan,Parag R. Gogate 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.21 No.1
The effect of ultrasonic reactors on the epoxidation of sunflower oil was investigated using two differentsonochemical reactors such as ultrasonic horn and ultrasonic bath. The optimized parameters for thesynthesis were established followed by scale up studies. Use of combination of ultrasonic bath andmechanical agitation gavemaximum conversion to oxirane oxygen as 91.1%. The synthesized epoxidizedsunflower oil (ESNO) was used as plasticizer in polyvinyl chloride sheets and the performance wasevaluated by thermogravimetric analysis and mechanical testing methods. It has been established thatESNO plasticizer has ability to replace dioctyl phthalate (DOP) giving a sustainable and greener approach.
