Increasing interest in biofuels has led to a desire to understand the phase characteristics of the compounds present in these fuels and how the dynamics of the fluid might be affected, especially close to their melting points. The relevance is that a biofuel in extreme low temperatures may undergo a phase change modifying its flow in fuel lines. One of the best biofuels is methyl oleate which has been studied already as part of another project. Intriguingly, this showed anomalous behaviour in the solid form. However, it is not clear whether this was simply a matter of a weak signal or some unexpected change in the material. Clarification of this is required by studying the parent compound oleic acid where we can progressively introduce limited order and hence separate the effects of signal intensity and changes in the material.
