Abstract

Se describe un proceso y aparato optimizados para llevar a cabo de manera más eficiente y economica la oxidacion de un compuesto oxidable. Tal oxidacion en ase líquida se lleva a cabo en un reactor de columna de burbujas que provee una reaccion sumamente eficiente a temperaturas relativamente bajas. Cuando el compuesto oxidado es el paraxileno y el producto de la reaccion de oxidacion es ácido tereftálico bruto (CTA), tal producto CTA puede purificarse y separarse mediante técnica más economicas que las que se emplearían si el CTA se formara por un proceso de oxidacion convencional de alta temperatura. Reivindicacion 1: Un proceso que comprende: (a) introducir una corriente de oxidante que comprende oxígeno molecular en una zona de reaccion de un reactor de oxidacion inicial; (b) introducir una corriente de alimentacion que comprende un compuesto oxidable en dicha zona de reaccion, donde dicho compuesto oxidable tiene un punto de ebullicion de al menos aproximadamente 50 degree C, donde al menos aproximadamente 10 moles por ciento de dicho compuesto oxidable están en estado gaseoso cuando se introducen en dicha zona de reaccion; y (c) oxidar al menos una porcion de dicho compuesto oxidable en una fase líquida de un medio de reaccion multi-fásico.A process and apparatus optimized to carry out the oxidation of an oxidizable compound is described more efficiently and economically. Such oxidation in liquid ace is carried out in a bubble column reactor that provides an extremely efficient reaction at relatively low temperatures. When the oxidized compound is paraxylene and the oxidation reaction product is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than would be used if CTA were formed by a conventional oxidation process. high temperature Claim 1: A process comprising: (a) introducing an oxidant stream comprising molecular oxygen into a reaction zone of an initial oxidation reactor; (b) introducing a feed stream comprising an oxidizable compound in said reaction zone, wherein said oxidizable compound has a boiling point of at least about 50 degree C, where at least about 10 mole percent of said oxidizable compound are in gaseous state when they are introduced into said reaction zone; and (c) oxidizing at least a portion of said oxidizable compound in a liquid phase of a multi-phase reaction medium.
