Abstract
The experimental temperature−composition phase diagram of the binary system between hexadecane (C16H34) and 1-hexadecanol (C16H33OH) has been established by combining thermal analysis and powder X-ray diffraction (XRD). Beforehand, crystal structures of the solid ordered phases of the components involved were determined from XRD data. Hexadecane displays a triclinic form Tp belonging to the space group P1, with Z = 1. The unit cell dimensions are a = 4.269 A, b = 4.811 A, c = 22.34 A, α = 84.54°, β = 67.43°, and γ = 73.00°. 1-Hexadecanol displays a monoclinic form γ belonging to the space group A2/a with Z = 8. The unit cell dimensions are a = 8.980 A, b = 4.939 A, c = 87.91 A, and β = 122.63°. The phase diagram between both components is characterized by two invariants, a eutectic (located at T = 289.5 K) and a metatectic (located at T = 318.8 K). The miscibility in the solid state is very restricted, limited to the regions rich in C16H34 and C16H33OH. Resulting alloys have led to the design of a double...
