1. A chemical synthesis method, said method comprising a Spray Flash Evaporation, also commonly referred to by the corresponding initialism SFE, which comprises the chemical reaction of at least one first compound with at least one second compound, under conditions in which the first compound and the second compound react to form at least one third compound, said method including the following steps (a) to (d):
(a) the preparation of a first liquid phase comprising the first compound in order to form a first liquid composition placed in a first tank, and the preparation of a second liquid phase comprising the second compound that forms a second liquid composition placed in a second tank;
(b) the heating of the first composition, under a pressure P1, at a temperature that is higher than the boiling point of the liquid, and the heating of the second composition, under a pressure P1′, at a temperature that is higher than the boiling point of the liquid; and
(c) simultaneous atomisation of the first and second compositions heated under pressure, in an atomisation chamber by means of at least one dispersion device under a pressure P2 that is lower than Pl and P1′; and
(d) obtaining said third compound by reacting of the first compound and the second compound.
