Artigo completo:

This paper contains the results of a new experimental study of the temperature effect on density and ultrasonic velocity for Brazil nut (Bertholletia excelsa), coconut (Cocos nucifera) and sucupira (Pterodon emarginatus Vogel) oils. Isentropic compressibilities and isobaric expansibilities were computed from the experimental magnitudes, as a function of temperature. The Halvorsen’s model (HM), and Collision Factor Theory (CFT) were selected for prediction of these properties, due to their wide range of application and easy computation. An accurate response was observed, despite of the use of several simplifications as molecular group contribution procedures for estimation of theoretical critical points of the fatty acids and the complex nature of the studied fluids.

Este trabalho apresenta os resultados de um novo estudo experimentalsobre o efeito da temperatura na densidade e na velocidade do som dos óleos denoz do Brasil (Bertholletia excelsa), coco (Cocos nucifera) e sucupira (Pterodonemarginatus Vogel). As propriedades derivadas compressibilidade isentrópica eexpansibilidade isobarica foram calculadas a partir dos valores experimentais, comofunção da temperatura. O método de Halvorsen (HM), e a Teoria do Fator de Colisão(CFT) foram selecionadas para modelar estas propriedades devido a o seu amplorange de aplicação e facilidade de implementação. O uso destes modelosmatemáticos apresentou baixos desvios apesar da simplificação introduzida naestimação dos pontos críticos dos ácidos graxos, procedimentos de contribuiçãomolecular de grupos funcionais e a natureza estrutural complexa dos óleos.
