2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Category: alcohols-buliding-blocks

Recycling waste polyethylene terephthalate (PET) fibers is critical for both environmental and resource protection. However, the PET fiber possesses good chem. stability and high crystallinity, resulting in the conversion of PET. Herein, we developed a strategy of stepwise feeding process to recycle PET fibers and recover the potential monomer by adding it to the glycolysis agent diethylene glycol after it had been warmed up to reaction temperature The results show a significant increase in the PET fiber conversion (92.5%) and yield of water-soluble products (70.4%) in 90 min as compared to a one-step feeding process of 28 and 14.4%, resp. These water-soluble products are monomers and dimers which are confirmed by Fourier transform IR spectroscopy, NMR spectroscopy, mass spectroscopy, and high-performance liquid chromatog. It is also obviously found that the conversion of PET and yields of fibers are lower than those of bottle flakes and particles. In addition, a ‘column shrinkage model’ is proposed to describe the glycolysis process of the fibers. The apparent reaction activation energy of fibers was derived as 27.19 kJ/mol, which is somewhat higher than those of PET bottle flakes and particles. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Category: alcohols-buliding-blocks).
