Synthetic Route of 4330-21-6, Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 4330-21-6, Name is Hoffer’s chlorosugar, SMILES is O=C(O[C@@H]1[C@@H](COC(C2=CC=C(C)C=C2)=O)O[C@H](Cl)C1)C3=CC=C(C)C=C3, belongs to dioxoles compound. In a article, author is Yampol’skii, YP, introduce new discover of the category.
Permeability of amorphous AF teflons to ozone
The permeability of glassy polymers to ozone was measured for the first time. The measurements were made on amorphous AF Teflons (DuPont), the copolymers of bis(trifluoromethyl-4,5-difluoro-1,3-dioxole) and tetrafluoroethylene with a cyclic comonomer content of 87 (AF2400) and 65 (AF1600) mol %, at 20-60 degrees C and an ozone partial pressure of 0-5.5 kPa in an ozone-oxygen mixture. It was shown that the obtained permeability coefficients depended neither on the amount of ozone in the mixture nor on the polymer film thickness (5-15 mu m) and were equal to 2160 and 525 Barrer (at 20 degrees C) for Teflon AF2400 and AF1600, respectively. The temperature dependences of permeability coefficients are qualitatively different for individual copolymers. The permeability of Teflon AF2400 decreased with increasing temperature (the apparent activation energy of permeability is negative, -9.3 kJ/mol), whereas normal behavior was observed for Teflon AF1600, i.e., the permeability coefficient grew with temperature. (The activation energy of permeability is 6.4-7.0 kJ/mol for films of various thickness.) This difference is due to an abnormally low activation energy of diffusion in AF2400, which has a high free volume.
