Definitions
- the present invention relates to the field of the production of binders based on fluxed bitumens used mainly in the production of road construction and / or civil engineering layers and / or coatings, and more particularly the production of fluxes entering the composition of these binders by chemical modification of fats of natural origin.
- Bitumen is the main hydrocarbon binder used in the field of road construction or civil engineering. It can be used pure or modified by adding polymers, it is then called modified bitumen.
- bitumen used in road binders is too viscous at room temperature to exhibit proper handling, or wettability with respect to aggregates.
- bitumen or modified bitumen manageable: either by heating according to its viscosity, or by placing it in emulsion or by lowering its viscosity by mixing with solvents or "fluxing", for the most part oil origin.
- bitumen regains its original properties, once implemented, whatever the technique used, respectively by cooling, by evaporation of the water of the emulsion or by evaporation of the solvent.
- the latter alternative leads to releases into the atmosphere of volatile organic compounds, releases not recommended for the environment and which represent a waste of fossil energy.
- fluxing agents also called fluxing oils, based on animal and / or vegetable fats (oils and fats), thereby avoiding the release of volatile organic compounds (VOCs).
- raw natural fats have a good solvent power for bitumen.
- they have a high viscosity, which can be decreased by conversion of triglycerides to monoesters.
- the patent application FR 2721043 (VIALIT) describes a bitumen emulsion containing a fluxing oil, said emulsion comprising 50 to 90% by weight of bitumen and 1 to 50% by weight of a fluxing oil, as well as an agent adhesion based on fatty amines or organic silicon.
- the fluxing oil may be a vegetable oil such as rapeseed oil, one of its derivatives such as its fatty acid part, a mixture of fatty acids, a transesterification product such as a methyl ester of rapeseed oil or an alkyd resin derivative of rapeseed oil.

- the oils used are methyl esters of rapeseed, flax or sunflower oils, which have optionally been isomerized beforehand.
- the conjugated double bonds of the fluxant reduce its initial viscosity and play a key role in the hardening of the binder.
- the hardening of the binder is obtained by crosslinking the fluxing agent in the presence of the oxygen of the air and the catalyst (metal salt of transition).
- the metal salts form -0-0- peroxide bridges on the unsaturated chains of the fatty acids. These bridges are unstable and lead to the formation of free radicals, which attack other chains, producing by propagation a polymerization-crosslinking of the esters.
- the application FR 2701021 (SCREG) describes an emulsion comprising a hydrocarbon-based binder, in particular a bitumen, and at least one drying or semi-drying, natural or synthetic drying oil or at least one standole of such an oil and generally a metal-type catalyst.

- the reaction mixture is stirred an additional 30-40 minutes at 70-75 ° C, taking care that the temperature does not exceed 75 ° C.
- the pH of the reaction mixture is measured.
- the total duration of the catalysis phase is generally between 60
- the reaction mixture is then cooled to 60-65 0 C, and subjected, after stopping the stirring, static decantation for 30 minutes at this temperature to separate the glycerol. It is possible to observe a difference in color between the glycerol (darker) and the methyl ester phase (very pale). The interface between the two phases is very clear. 9 kg to 9.5 kg of glycerol formed are withdrawn from the bottom of the reactor.
- the racking is carried out in two stages: a) fast racking representing of the order of 90% of the estimated quantity, ie approximately 8.25 kg; (b) much slower withdrawal, which makes it possible to promote, as completely as possible, the elimination of glycerol. Because of its high viscosity, it tends to stick along the walls and therefore requires a certain time to accumulate completely in the lower part of the reactor.
- the washing of the "ester" phase is carried out in the R100 reactor as follows.
- a first washing is accomplished by introducing into the reactor 3% by mass demineralized water relative to the mass of the rapeseed oil involved, or 1.5 kg.
- the use of demineralized water avoids the presence of calcium salts.
- the mixture is stirred for 5 minutes at 60-65 0 C, the stirring is stopped and the mixture subjected to decantation for 20 minutes.
- the lower phase (3 kg to 3.5 kg of a mixture of water / methanol / glycerol and potassium soaps) is withdrawn.
- the pH of wash water is measured.
- a second washing is accomplished by introducing into the reactor 3% by mass demineralized water relative to the mass of rapeseed oil involved, or 1, 5 kg.
- the mixture is stirred for 10 minutes at 60-65 0 C, the stirring is stopped and the mixture subjected to decantation for 30 minutes.
- the lower phase (3 kg to 3.5 kg of a mixture of water / methanol / glycerol and potassium soaps) is withdrawn.
- the pH of wash water is measured.
- the reaction mixture is dried in the R100 reactor rapidly to avoid any hydrolysis and oxidation phenomena, as follows.
- the reaction mixture is heated under a dynamic vacuum ( ⁇ 10 mm Hg) and with stirring at 110-125 ° C. to remove both traces of water and approximately 0.5 to 1% of residual methanol. These conditions are maintained for 30 to 60 minutes until the boiling of the product is complete, or until a water test results ⁇ 200 ppm.
- the recovered ester mixture has sufficient purity, evaluated by HPLC or gas chromatography (GC), to be able to be engaged in the oxidation step. It is not necessary to completely eliminate potassium ions because the esters are treated by molecular distillation.
- the ester mixture is stored in opaque polypropylene 30 L or 5 L cans under a nitrogen atmosphere to avoid any oxidation reaction.
- the fluxing agents obtained have the advantage of not evaporating in the atmosphere, but of hardening rapidly in the bitumen once the bituminous binder has been applied to a surface.
