Technology advances over time, people's average age has been rising , more and more about human health, so the anti-oxidant drugs may allow people to eat food to maintain freshness and taken seriously.
In this study, supercritical carbon dioxide to sodium ascorbate (Sodium Ascorbate) and L-ascorbic palmitate acid (Ascorbyl Palmitate) solubility experiments, the supercritical carbon dioxide on sodium ascorbate and L-ascorbic acid palmitate solubility test of these two drugs, the use of UV-Visible to test the critical state of these two kinds of carbon dioxide dissolved in the concentration of drugs, try to find sodium ascorbate and L-ascorbic acid palmitate in the carbon dioxide critical-state temperature and pressure.
Study the pressure range from 10 MPa, 12 MPa, 14 MPa, 16 MPa, 18 MPa, 20 MPa, 22 MPa and 24 MPa, temperature 313.15 K, 323.15 K and 333.15 K under the carbon dioxide emissions under the flow rate set 5.0L/min solubility experiments.
