Zusammenfassung:	The present invention relates to a method for producing dehydro rose oxide by reacting isoprenol and prenal in the presence of at least one sulfonic acid of formula R1-SO3H as catalyst, wherein R1 is selected from phenyl which carries 2 or 3 C1-C4-alkyl substituents, phenyl which carries one C8-C20-alkyl substituent and optionally also 1 or 2 C1-C4-alkyl substituents, and naphthyl which optionally carries 1 or 2 C1-C4-alkyl substituents. La presente invención se refiere a un método para producir deshidro-óxido de rosas haciendo reaccionar isoprenol y prenal en presencia de por lo menos un ácido sulfónico de la fórmula R1-SO3H usado como catalizador, en el que R1 es seleccionado de entre fenilo que porta 2 o 3 substituyenes C1- C20-alquilo, fenilo que porta un substituyente de C8-C20-alquilo y opcionalmente también 1 o 2 substituyentes de C1-C4-alquilo, y naftilo, que porta opcionalmente 1 o 2 substituyentes de C1-C4-alquilo.
