Abstract

The data presented in this article relates to the crystallisation of 8 single n-alkanes, C₁₆H₃₄ - C₂₃H₄₈ in representative diesel solvents dodecane and toluene, as well as a mixture of these 8-alkanes with a composition representative of real diesel fuel in the same solvents. For the single alkane systems, the data was collected over a range of 5 concentrations ranging from 0.09 - 0.311x_i, depending upon the system, and 4 concentrations for the 8-alkane mixture, 0.1 - 0.5x_i. Raw average crystallisation and dissolution points as a function of cooling rate (q) from a polythermal methodology are presented. Along with the equilibrium crystallisation and dissolution temperatures, van't Hoff fitting parameters, relative critical undercooling (u_c) values as a function of q as well as the calculated values of K_G and α_det.
