Abstract
This application relates to certain dimers as crystallization depressants for biodiesel fuels, and methods for making the same. Such dimers, due to their particular structure and conformation, disrupt the regular packing of linear saturated fatty acid methyl esters, thereby delaying nucleation and mitigating crystal growth. In some embodiments, the dimer includes (E)-1-(1-(oleoyloxy)-3-(stearoyloxy)propan-2-yl) 18-(1-(oleoyloxy)-3-(stearoyloxy)propan-2-yl)octadec-9-enedioate.
