Technology Process of Sodium hydroxide

There total 403 articles about Sodium hydroxide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 100.0%

Na2[B(CN)3] + water (7732-18-5) + potassium carbonate (584-08-7) → K[HB(CN)3] + sodium carbonate (497-19-8) + sodium hydroxide (1310-73-2)

Guidance literature:

With tetrahydrofuran;

Reference yield: 58.0%

selenium (7782-49-2) → sodium selenate + sodium carbonate (497-19-8) + sodium hydroxide (1310-73-2)

Guidance literature:

With sodium peroxide; In neat (no solvent); byproducts: Na2SO4; oxidation of Se on melting with Na2O2in a Ni crucible;; the formed melt contains NaOH and Na2CO3; isolation as mixture of Na2SeO4 and Na2SO4;;

Reference yield:

water (7732-18-5) + sodium hydride (7646-69-7) → hydrogen (1333-74-0) + sodium hydroxide (1310-73-2)

Guidance literature:

In neat (no solvent); exothermic react., react. enthalpy given;;
