Application Note: Microwave-assisted extraction of antioxidants from polyolefins
28 February 2024

Irgafos 168, identified chemically as Tris(2,4-di-tert-butylphenyl) phosphate, is a paragon of efficacy in the protection of polyolefins against oxidative stress. It executes its protective function through a dual-pronged strategy. In this application note, explore a microwave-assisted extraction on Irgafos 168 and its degradation product as it is carried out in different types of polyolefins using the Milestone ETHOS X microwave extraction system equipped with the Milestone fastEX-24 rotor, followed by quantification by GC-MS chromatography. The results obtained by microwave extraction of polypropylene are also further compared with ultrasonication and Soxhlet techniques.
