Procedure to obtain biodiesel fuel with improved properties at low temperature

摘要: Procedure to generate biodiesel fuels with improved properties at low temperature by the transesterification of triglycerides alcohols such as methanol or ethanol, optionally in presence methyl ethyl acetates fatty acids and an inert solvent, produce esters acids, glycerine and, where appropriate, triacetate, followed separation crude that is reacted aldehydes, ketones and/or acetic acid acetals, cetals acetates. The are mixed concentrations approximately 0.5-20% weight obtain a temperatures.
