Abstract:
1. A process for making a polyester monomer from a plurality of reactants comprising: (a) providing an esterification pipe reactor having a first inlet and a first outlet; (b) adding at least one reactant under esterification reaction conditions into the esterification pipe reactor proximal to the first inlet; wherein a liquid phase and a vapor phase flow through the esterification pipe reactor, wherein the esterification pipe reactor is operated in at least one flow regime selected from the group consisting of bubble flow, plug flow, stratified flow, wavy flow, slug flow, dispersed flow, and froth flow; wherein at least a portion of the reactants form a polyester monomer; and wherein the fluid flowing through the esterification pipe reactor is a process fluid.
