Lattice paramters of solid solutions of long-chain n-alkanes

Crystal lattice parameters of mixtures of the normal alkanes n-C₂₃H₄₈ and n-C₂₅H₅₂ have been determined by X-ray powder diffractometry. The c-axis length increases nearly monotonically with increasing C25H₅₂ content, a and b are larger for the mixtures than for the pure substances with maximum values at 15% n-C₂₅H₅₂. The small but significant increases in a of 0.6% and b of 0.9% have not been previously reported.
