Resumo
Neste trabalho, a equação de estado de Peng-Robinson EOS foi escolhida para representar o comportamento da fase líquida. Então, considerando os três ácidos, Laurico, Palmitico e Esteárico, os coeficientes módulo de massa foram calculados em três valores de pressão (0,1, 1,0 e 2,0 GPa) e na faixa de temperatura de 350-450 K. De acordo com a literatura, resultados para o dióxido de carbono, o módulo de massa na fase líquida está na mesma linha para o referido em fase sólida considerando a variável temperatura. Baseado nisso, neste trabalho o módulo de massa foi estimado em três temperaturas para os três ácidos na fase sólida pela extrapolação dos resultados na fase líquida. Apesar de não existir dados experimentais na literatura, estes resultados parecem estar consistentes com as restrições termodinâmicas e discussões úteis foram obtidas.
