Sodium hydroxide is industrially produced as a 50% solution by variations of the electrolytic chloralkali process. Chlorine gas is also produced in this process. Solid sodium hydroxide is obtained from this solution by the evaporation of water. Solid sodium hydroxide is most commonly sold as flakes, prills, and cast blocks. In 2004, world production was estimated at 60 million dry tonnes of sodium hydroxide, and dem… Witryna24 paź 2014 · The synthetic method of sodium polyacrylate comprises the following steps of adding a sodium hydroxide aqueous solution in acrylic acid to adjust pH to 7-8, adding an initiator in a neutralized... pitch black material https://a-kpromo.com
