Abstract
An exothermic process for forming a product which may be in a liquid phase is disclosed wherein a first reactant, preferably a liquid reactant, is directly fed into a reaction zone containing mixing elements and which comprises a first compartment of a reactor. A second reactant, which is maintained at a higher pressure, is fed into a second compartment of the reactor separated from the first compartment by a porous wall. The second reactant passes through this porous wall into the reaction zone to react with the first reactant. The process thereby controls rates of the reactions and the exothermic heats generated by the reactions. Pulsatile flow in one or both reaction compartments improves mixing. An evaporator for a portion of the product improves product quality and permits higher reaction temperatures in the reactor.
