  2. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Bringing water to its boiling point (about 100 °C or 212 F at sea level), is the oldest and most effective way since it eliminates most microbes causing intestinal disease, [19] but it cannot remove chemical toxins or impurities. [20]

    Boiling or heating water cannot remove PFAS from water. Bottled water may be safer, but there’s no guarantee. The FDA regulates bottled water and doesn’t currently have any standards for PFAS ...

  4. Styrene-acrylonitrile resin - Wikipedia

    en.wikipedia.org/wiki/Styrene-acrylonitrile_resin

    Like polystyrene itself, it is transparent and brittle. The copolymer has a glass transition temperature greater than 100 °C owing to the acrylonitrile units in the chain, thus making the material resistant to boiling water. It is structurally related to ABS plastic, where polybutadiene is copolymerised with SAN to give a much tougher material ...

    en.wikipedia.org/wiki/Purified_water

    Double-distilled water (abbreviated "ddH 2 O", "Bidest. water" or "DDW") is prepared by slow boiling the uncontaminated condensed water vapor from a prior slow boiling. Historically, it was the de facto standard for highly purified laboratory water for biochemistry and used in laboratory trace analysis until combination purification methods of ...

  7. Boiling - Wikipedia

    en.wikipedia.org/wiki/Boiling

    The boiling point of water is 100 °C (212 °F) at sea level and at normal barometric pressure. [9] In places having a proper water purification system, it is recommended only as an emergency treatment method or for obtaining potable water in the wilderness or in rural areas, as it cannot remove chemical toxins or impurities. [10] [11]

  9. Polylactic acid - Wikipedia

    en.wikipedia.org/wiki/Polylactic_acid

    The condensation reaction is reversible and subject to equilibrium, so removal of water is required to generate high molecular weight species. Water removal by application of a vacuum or by azeotropic distillation is required to drive the reaction toward polycondensation. Molecular weights of 130 kDa can be obtained this way.
