Abstract
Pressão interna, volume livre, refração molar e propriedades termodinâmicas de excesso de misturas líquidas binárias de dimetil sulfóxido + tiofeno e dimetil sulfóxido + piridina a 298.15 K foram calculadas a partir de medidas experimentais de densidades, tensão superficial e índice de refração. A relação entre a pressão interna, volume molar de excesso, refração molar, e a interação molecular dos sistemas binários é examinada.
