β¦ Synopsis
The extraction of natural products with compressed carbon dioxide has already found industrial application. Studies on the model substance Ξ±βtocopheryl acetate showed that its solubility (i) increases in liquid and supercritical CO~2~ with increasing pressure and (ii) changes comparatively little when CO~2~ is warmed at constant pressure from subcritical to supercritical temperature.

## Abstract In the present work, new experimental data are presented on the solubility of carbon dioxide in aqueous piperazine solutions, for concentrations of 0.2 and 0.6 molar piperazine and temperatures of 25, 40, and 70Β°C respectively. The present data, and other data available in the literatur
Polyphenylacetylene was prepared by transition metal catalysis in compressed (liquid and supercritical) CO 2 . Surface morphology, IR and NMR spectroscopic properties of the resulting materials are discussed in terms of the microstructure of polymers.
