Procedure
In the fully continuous process variant, catalyst and geraniol or nerol, or a mixture of geraniol and nerol, are simultaneously and continuously metered into a continuous reactor and linalool which is formed is continuously distilled off. In addition, high boilers are discharged by likewise continuously withdrawing a fractional amount of the reactor contents and removing the geraniol, nerol and linalool products of value still present in this fraction from high boilers formed during the reaction by distillation, for example by a simple evaporation or using a column. The involatile catalyst either remains in the high boilers which are fed to a disposal operation, or it may be precipitated from the high boilers by cooling, removed and reused again. The products of value which have been distilled off are recycled back into the reactor.
