Application of a Generalized Maximum Likelihood Method in the Reduction of Multicomponent Liquid-Liquid Equilibrium Data

Abstract: The equations of the method based on the maximum likelihood principle have been rewritten in a suitable generalized form to allow the use of any number of implicit constraints in the determination of model parameters from experimental data and from the associated experimental uncertainties. In addition to the use of any number of constraints, this method also allows data, with different numbers of constraints, to be reduced simultaneously. Application of the method is illustrated in the reduction of liquid-liq… Show more

“…A composição do biodiesel foi analisada por cromatografia gasosa com detector de ionização de chama (FID). O Glicerol foi fornecido pela Vetec, com grau de pureza superior a 99,5%, já o metanol fornecido pela Synth, com grau de pureza superior a 99,8%; ambos sem processos extras de purificação Os dados experimentais foram determinados através do uso de células de vidro encamisadas, em conformidade com Stragevitch (1997). Essas são providas de coletores laterais vedados por septos que permitem a coleta de amostras de cada fase, por seringas, sem que haja perturbação do equilíbrio.…”
