Methods and apparatuses for controlling exothermic reactions involving a first reactant contained in a liquid and a second reactant in a gas to form a reaction product by atomizing the liquid in an environment of a gas and removing heat of reaction by condensing vapors of the liquid in a reaction chamber. Preferably, the condensation takes place on a simultaneously atomized second liquid of lower temperature than the atomized liquid containing the first reactant. The compositions of the two liquids are preferably similar. This invention provides waste minimization and considerable environmental improvement.

[ What is claimed is:] [1.] A method of forming a polymer wherein a reaction product different than carbon monoxide or carbon dioxide is made in a reaction zone by reacting a first reactant contained in a first liquid with a second reactant contained in a gas, the first reactant and the second reactant characterized by an ability to react with each other in an exothermic manner, the method comprising the steps of:atomizing the first liquid to form a plurality of first droplets having an average droplet size in the gas at a first flow rate, at a first atomization temperature, and at a reaction pressure;reacting at least partially the first reactant with the second reactant to form the reaction product and release heat;evaporating at least part of the first liquid, thereby removing at least a portion of the released heat; andrestricting the portion of removed heat within predetermined limits by causing controlled condensation within the reaction zone; whereinthe first reactant comprises a compound selected from a group consisting of cyclohexane, cyclohexanone, cyclohexanol, cyclohexylhydroperoxide, o-xylene, p-xylene, m-xylene, a mixture of at least two of cyclohexane, cyclohexanone, cyclohexanol, and cyclohexylhydroperoxide, and a mixture of at least two of o-xylene, p-xylene, and m-xylene;the second reactant comprises oxygen;the reaction product comprises a compound selected from a group consisting of adipic acid, phthalic acid, isophthalic acid, and terephthalic acid; andthe method further comprises a step of reacting said reaction product with a third reactant selected from a group consisting of a polyol, a polyamine, and a polyamide in a manner to form a polymer of a polyester, or a polyamide, or a (polyimide and/or polyamideimide), respectively.
