- We report on the preparation and selected properties of some new biodiesels which we synthesized from oils of plants growing in Northern Wisconsin and Minnesota. The composition and the low-temperature properties such as crystallization onset T c and end of melting T m investigated with the help of differential scanning calorimetry are presented. Some of these biodiesels exhibited remarkably good low-temperature characteristics. In order to further improve these properties, we use a variety of alcohols during the transesterification process, including isopropyl, 2-butyl, and isoamyl alcohols. Using several parameters such as oil content and crystallization onset temperature T c, plant species that appear most promising have been identified, among those highbush cranberry (T c ≈ −31 °C for its methyl esters, T c ≈ −41 °C for its 2-butyl esters), dotted horsemint (T c ≈ −17 °C for its methyl esters, T c ≈ −40 °C for its 2-butyl esters), and American hazelnut (T c ≈ −19 °C for its methyl esters, T c ≈ −30 °C for its 2-butyl esters).
