WebMay 9, 2012 · In the case of weight fraction analysis (which is the focus of this paper), particle size distribution is a bit of a misnomer. It has the natural meaning of frequency distribution of size across particles. What is really under discussion is the cumulative weight fraction of the material as a function of particle size. Webplus (C7) fractions can be grouped into three main tasks.1–3 1. Dividing the C7 fraction into a number of fractions with known molar compositions. 2. Defining the molecular weight, specific gravity, and boiling point of each C7 fraction. 3. Estimating the critical properties an d a centric factor of each C 7
