Abstract

Un proceso continuo para la preparación de ésteres alfahidroxicarboxílicos, en el cual los reactivos que reaccionaron son alfa-hidroxicarboxamida con alcohol en presencia de un catalizador para obtener una mezcla del producto que comprende un éster alfa-hidroxícarboxílico, amoniaco, alfa-hidroxicarboxamida no convertida y alcohol, y catalizador; caracterizado por que a') los flujos de reactivo comprendiendo, como reactivos, un alfa-hjdroxjcarboxamjda, un alcohol y un catalizador son alimentados en un reactor de presión; b') los flujos de reactivo se hacen reaccionar entre si en el reactor de presión a una presión en el rango superior a 1 bar a 100 bar; c') la mezcla del producto que resulta del paso b') y que comprende un éster alfa-hidroxicarboxílico, alfa 20 hidroxicarboxamida no convertida, alcohol amoniacal y el catalizador es descargada del reactor de presión; y ci') la mezcla del producto es empobrecida en alcohol y amoniaco mediante separación por destilación del amoniaco a una presión que se mantiene constantemente superior a 1 bar sin la ayuda del agente de separación adicional. El proceso continuo puede ser empleado en una forma particularmente ventajosa a escala industrial.
