Abstract

Mejoras introducidas en un método de coproducción de estireno y de un óxido de alquileno inferior, en el cual una corriente de etilbenceno se oxida en hidroperóxido de etilbenceno, dicho hidroperóxido de etilbenceno se utiliza para reaccionar con una olefina para preparar una corriente de un óxido de alquileno inferior, una corriente que contiene metilbencilalcohol se hace pasar a través de una zona de deshidratación para preparar vapor y estireno, una corriente de acetofenona que contiene varias impurezas constituye un subproducto, una corriente conteniendo metilbencilalcohol se prepara mediante hidrogenación de una corriente conteniendo acetofenona conjuntamente con hidrógeno sobre una capa de partículas de catalizador que consiste en óxido de cinc que soporta cantidades catalíticas de cobre a una temperatura superior a la temperatura ambiente y una presión superior a la presión atmosférica, dicho estireno y dicho óxido de alquileno inferior se recuperan por separado como coproductos de la operación.
