Sodium dispersion in paraffin wax or oil
A) Sodium dispersion in paraffin wax
- approx. 33% sodium content
- approx. 67% paraffinic wax
- Easily handled as a dispersion in wax
We also offer advice on building a dispersion system for the production of sodium dispersion in oil
B) Sodium dispersion in oil
- approx. 33% sodium content
- approx. 67% paraffinic white oil thinly viscous
- as a dispersion in oil
- Easy to handle as a dispersion in wax
The reaction rate depends on the temperature but also on the form of the sodium used. The graphic shows the influence of particle size on the reaction rate.

C) Use of sodium dispersion
Sodium dispersion finds attractive use in organic synthesis because of the extremely high surface area of the reactive metal.
In reactions with sodium below 98 °C, the metal is present heterogeneously in the reaction medium. In order to increase the surface area, which is crucial for the reaction rate, sodium is dispersed in inert solvents or oils above its melting point using a high-quality dispersing unit.
The advantages of a dispersion include: E.g.:
- Feasibility of synthesis at low temperatures
- Shorter response times (see graphic)
- Better controllability of the reaction
- High yields
- easy to handle
- largely insensitive to air
Examples of beneficial uses of dispersion include:
- Organic syntheses in general
- Re-refining of waste oil
- Dechlorination of liquid residues containing CHCs Production of alcoholates
- Production of organic sodium compounds from alkyl and phenyl halides
- Preparation of cyclopentadienyl sodium and homologues
- Production of sodium hydride
Storage:
HALEX® can be stored indefinitely under correct storage conditions. There must be no open water points or pipes carrying water in the storage rooms. Sprinkler systems are not permitted.
