Abstract
Un procedimiento mejorado para preparar un catalizador soportado sobre sílice que comprende: secar el soporte de sílice a una temperatura de aproximadamente 100 a 300ºC durante un periodo de tiempo suficiente para eliminar del mismo el agua adsorbida en la superficie, tratar el soporte tratado térmicamente de este modo con cantidades suficientes de compuesto hidrosilano para que reaccione el compuesto hidrosilano con los grupos OH existentes en dicho soporte.
