Abstract
Abstract Reaction between a liquid reagent and a gaseous reagent wherein at least one of the products is a liquid is carried out by first mixing the liquid reagent with liquid product, so that the reaction with the gaseous reagent is carried out while the liquid reagent is in a solution of the liquid product. The mixture of liquid reagent and liquid product is contacted with the gaseous reagent while the liquid mixture is in rapid circulation. The device for carrying out an exothermic reaction between a gaseous reagent and a liquid compound, wherein at least one of the products of the reaction is liquid is provided with means for mixing the liquid reagent with the liquid product, at least one reaction conduit connected to the mixing means wherein the liquid mixture is put into rapid circulation and into contact with the gaseous reagent, means for controlling the temperature of the reaction conduit and means for feeding the gaseous reagent into the reaction conduit.
