    摘要： The invention concerns a chemical reaction process performed in a reaction chamber (1) which contains a catalyst bed, the reaction chamber (1) comprising a first end (2) and a second end (3), opposite the first end (2), the process involving alternately: a reaction phase, in which a reaction flow passes through the reaction chamber (1) from its first end (2) towards its second end (3); and a catalyst-regeneration phase, in which a regeneration flow passes through the reaction chamber (1) from its second end (3) towards its first end (2). The reaction chamber (1) preferably consists of a plurality of separate reaction compartments containing a catalyst bed and a heat-exchange system for exchanging heat therebetween.

    摘要： The invention relates to a process for synthesizing a nitrile-fatty acid (heminitrile) from unsaturated fatty acids, in the form of an acid or a simple ester or a "complex" ester of triglyceride type, which is first of all converted into an unsaturated fatty nitrile which is subjected to oxidative cleavage using H2O2 as oxidizing agent. This process can be used for preparing polyamide monomers, such as ?-amino acids or diamines or diacids equivalent to said heminitrile and for obtaining polyamides from raw materials which are of natural origin and from a renewable source.

    摘要： The present invention relates to a method for synthesizing acrolein, coupling the dehydration of glycerol into acrolein using a reaction for condensing aldol from acetaldehyde, produced in the impure state during dehydration, by means of formaldehyde. Specifically, the method according to the invention involves subjecting the gaseous effluent from the glycerol dehydration reaction to cooling, then proceeding firstly, in a first area, to water cleansing and condensation of said gaseous effluent so as to then separate, in a second fractionation area, firstly, a light aldehyde-rich flow from, secondly, a water-rich flow and, thirdly, the acrolein flow and then reacting the acetaldehyde, contained in the light aldehyde-rich flow from the previous step, with formaldehyde so as to obtain a second acrolein-rich flow by means of an aldol condensation reaction according to the following reaction diagram: CH
    3 -CHO + CH
    2 O ⃗ CH
    2 =CH-CHO + H
    2 O; and recirculating said second acrolein-rich flow into the previous step.

    摘要： The invention relates to a method for producing an acrylic ester (co)polymer including a first step consisting of esterifying a technical acrylic acid comprising renewable carbon, a second step which involves polymerising said ester in a liquid phase according to a process selected from polymerisation in an emulsion or in a solution under conditions such that the polymer formed within the reaction medium is in the form of a more or less viscous liquid in the reaction medium, and a final third step which involves subjecting the formed polymer fraction, as applicable after separating the bulk of said polymer from the reaction medium, to a separation treatment using the thin film technique. The method according to the invention reduces the highly restrictive phases of purification by distillation and/or crystallisation of acrylic acid performed prior to esterification and actual polymerisation, and is particularly suitable for the production of acrylic ester (co)polymers containing carbon from renewable sources.
