Abstract

Procedimiento para la obtención de Citral. La presente invención se refiere a un procedimiento mejorado para la obtención de 3, 7-dimetil-octa2, 6-dien-1-al (Citral) mediante disociación térmica de 3-metil-2-buten-1-al-diprenilacetal. En este caso se trata de una reacción realmente compleja, que -como puede verse por el esquema de reacción - trascurre a través de tres etapas.
