Conditioning of Organic Pigments in Carbon Dioxide
Eliáš, Z. ; Vyňuchal, J. ; Krystyník, Pavel ; Klusoň, Petr
A patent review in area of conditionation of organic pigments in supercritical fluid was presented. The results of conditioning with various polycyclic pigments and azo dyes in supercritical CO2 were discussed. Special attention was paid to unpublished extractional conditioning that can lead to significant removal of residual solvents or contaminants from pigments with lower expenses and shorter time than with utilization of well-estabilished current procedures.
