摘要： The present invention relates to a method for the transesterification of a hydroxylated oil including two consecutive transesterification steps performed in the presence of a light alcohol (methanol or ethanol) and a basic catalyst under temperature, pressure and alcohol/oil weight ratio conditions enabling the nearly total conversion of the hydroxylated oil into fatty acid esters. Characteristically, a resulting directly from the first transestrefication step in order to obtain a reaction mixture including, in particular, hydroxylated fatty acid esters and glycerol. Said reaction mixture is subjected to a separation step that makes it possible to obtain a less dense phase predominantly consisting of fatty esters and a denser phase predominantly consisting of glycerol and water and fatty acid soaps. The second transesterification step is performed on the less dense phase, with said light alcohol and said basic catalyst are added thereto.

摘要： The present invention relates to the manufacture of bioresourced acrolein and bioresourced acrylic acid from glycerol as starting material and more particularly comes within the scope of a process for the manufacture of acrolein and acrylic acid according to which the reaction for the dehydration of glycerol to give acrolein is carried out and a stage of oxidizing a water-rich phase separated from the reaction mixture coming from this dehydration reaction is carried out, before it is recycled to the glycerol dehydration stage. This oxidation treatment prevents organic impurities from accumulating during the process, while minimizing the consumption of water and the discharge of polluted aqueous streams.
