摘要
It is conventionally assumed that refractive index (RI) for a crude oil, a processed fuel or any petroleum-based solution may be evaluated in an assumption of an ideal binary mixture of non-precipitating components. However, new experimental data reveal strong nonideality of RI in dilute oil solutions, which we attribute to de-aggregation of asphaltenes. (C) 2007 Elsevier Ltd. All rights reserved.
