    Patent number: 9347007
    Abstract: Microcrystalline paraffin having a consistency in a rage of paste-like to solid, prepared by catalytic hydroisomerization of FT paraffins having a carbon chain length distribution in a range of 20 to 105 at temperatures above 200° C., and being free of aromatic compounds, heterocyclic compounds, and naphthenes.
    Type: Grant
    Filed: May 19, 2003
    Date of Patent: May 24, 2016

  • Microcrystalline paraffin
    Patent number: 7875166
    Abstract: The invention relates to a novel and completely synthetic microcrystalline paraffin, said paraffin being obtained in a simple manner and with a high yield by the catalytic hydromerisation of paraffin FT comprising 20 to 105 carbon atoms. Said paraffins can be pasty to solid at room temperature and have a higher percentage of iso-paraffins than n-paraffins. Since they do not contain aromatic compounds they are particularly suitable for use in the pharmaceutical, cosmetic and food industries.
