“…No intuito de fazer a correlação do comportamento dos dados experimentais, fornecido por LAGO et al 2009, com o comportamento predito pelo software PR baseado no modelo Peng-Robinson, foram calculados os erros relativos para se observar o quão próximo do valor real os dados experimentais estão e para qual isoterma obteve-se o menor erro médio. É relevante observar que os menores erros ocorreram para temperaturas maiores e menores pressões.…”

“…For polymer plasticization, high-pressure carbon dioxide > carbon dioxide-expanded hexane > hexane = air ≈ 0. [40], density and specific heat capacity [41], diffusion coefficient in air at ambient condition [42] for acetone, viscosity and density for carbon dioxide [43] and for hexane [44]. After densities and compositions of the hexane-carbon dioxide mixtures were determined by a set of parallel experiments in which the feeding processing in the ES chamber was repeated in a variable-volume view cell, the viscosities of the hexane-carbon dioxide mixtures were estimated using the "Katti-Chaudhri" mixing rule [40].…”

“…Dzida and co-workers have studied u(T,P) for n-alkanes, alcohols and their mixtures, and have discussed their results from a physical chemistry point of view. The research groups of Lago et al, [91][92][93][94][95][96][97][98][99][100] Kabelac et al, [101][102][103][104] Guedes et al, [106][107][108][109] Trusler et al [110][111][112] and others 105,113,114 have reported measurements of u(T,P) on compounds such as: water, hydrocarbons, refrigerants, oils over a wide range of temperature and pressure. Research on the u(T,P) for biomassderived fuels and related compounds has recently been reported.…”

“…119 For acetone, the speed of sound over the temperature range of 248 to 298 K and for pressures up to 100 MPa, was measured by Lago and Albo. 95 They estimated the density r(T,P) by numerical integration of u À2 using Equation (13.5). The critical temperature, T c , for toluene is 591.80 K, and for acetone it is 508.10 K. In order to compare the k S (T,P) values of the two chemicals, the values for acetone at T ¼ 298.15 K were plotted in Figure 13.8(a).…”
