Carbonate phase change materials

Phase change materials that include oleochemical carbonates absorb and release latent heat upon changing phases from solid to liquid (melting) or from liquid to solid (solidifying). The oleochemical carbonates are prepared from oleochemical alcohols derived from animal fats and vegetable oils or other bio-based substances. These oleochemical carbonates have melting temperatures with a relatively high heat of fusion and are non-corrosive. Oleochemical carbonates can be mixed together in various proportions to adjust melting/solidification temperature ranges as required by a particular application.
