Traceability and control of phenolic odorants in production process of recycled polypropylene

Analysis & Ageing | 更新时间：2026-02-03

- Traceability and control of phenolic odorants in production process of recycled polypropylene
- “Using headspace solid-phase microextraction gas chromatography-mass spectrometry/olfactory coupling technology, the volatile components in the production process of recycled polypropylene were systematically analyzed, and 2,4-di-tert-butylphenol was identified as a key odor indicator, providing a theoretical foundation for optimizing process parameters and developing efficient odor control technologies for recycled plastic production enterprises.”
