1. A device for preparing a reaction product from a first liquid containing a first reactant and a gas containing a second reactant comprising:

  • a reaction chamber having an upper end, a lower end, a wall, and a reaction zone, in which zone the first liquid is brought in contact with the gas for reacting at a reaction pressure;

    an atomizer disposed within the reaction chamber adapted to break the first liquid into a plurality of droplets within the gas at an atomization temperature in a manner that the droplets coalesce on a mass of a second liquid containing reaction product, the droplets having a pre-coalescing temperature before they coalesce, the mass of the second liquid having a second liquid surface, the atomizer being away from said second liquid surface at an atomization distance;

    a first temperature monitor for measuring the atomization temperature;

    a second temperature monitor for measuring the pre-coalescing temperature;

    control means connected to the first and the second temperature monitors for obtaining temperature information and pointing a parameter or determinant selected from a group consisting of pre-coalescing temperature of the droplets, transient temperature difference of the droplets, and a combination thereof, toward respective predetermined ranges, the transient temperature difference of the droplets being the difference between the pre-coalescing temperature and the atomization temperature; and

    a separator communicating with the reaction chamber for separating the reaction product from the second liquid.
