The Peng-Robinson1 equation of state was used to correlate the solubility of caffeine with a thermodynamic model and two mixing rules were evaluated: the classical mixing rule of van der Waals with two adjustable parameters (PR-VDW) and a density dependent one, proposed by Mohamed and Holder2 with two (PR-MH, two parameters adjusted to the attractive term) and three (PR-MH3 two parameters adjusted to the attractive and one to the repulsive term) adjustable parameters. The best results were obtained with the mixing rule of Mohamed and Holder2 with three parameters.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-11-23T12:13:38Z No. of bitstreams: 1 a09v31n6.pdf: 271231 bytes, checksum: d25c9fe1e7ab274f649fc60dc203bfe7 (MD5)Made available in DSpace on 2011-11-23T12:13:39Z (GMT).
