Preparation of aqueous dispersions of paraffin and ceresin

Resumo

The process of preparing aqueous dispersions of solid petroleum hydrocarbons was studied. Stable aqueous dispersions of petroleum paraffin can be prepared using polyvinyl alcohol in combination with a hydrotropic additive as a stabilizer. While for stabilization of dispersion of ceresin, which is a microcrystalline wax, it is necessary to use an anionic surfactant.
