Dissolution of the pharmaceutical substance Acizol® — bis(1-vinylimidazole-N) zinc diacetate — in supercritical carbon dioxide (SC-CO2) is studied using the FTIR spectroscopy. Via the analysis of temporal dependences of integral intensities of IR absorption analytical band (1650 сm-1) at varied acizol shot its molar fraction in saturated solution in carbon dioxide at 40 °C and 10,0 MPa is evaluated as (4,9 ± 1,3) • 10-3.
