Sodium is a byproduct of the production of pentaerythritol, pentaerythritol crystal accelerator
Uses
Sodium is a byproduct of the production of pentaerythritol, pentaerythritol crystal accelerator activation by the venom can make the product composition of the sodium content of ≥ 97%, organic content ≤ 2%, water 2%, chloride content 0.5%, now the technology has reached the international advanced level, in the domestic leading position. Sodium is mainly used for production of formic acid, oxalic acid and sodium hydrosulfite, can also be used to prepare the reducing agents and disinfectants.
