Method for preparing aldehyde camfolenico from Alpha Alpha - PINENE using a catalyst and removing the aldehyde by distillation of the Reaction Medium.

摘要

It provides a process for producing aldehyde to canfolenico is useful as a Chemical Intermediate for other Synthetic aromatic and aromatic Chemicals,In particular those with smell of Sandalwood and also for some drugs.In particular,The Invention includes a continuous process for aldehyde to canfolenico Racemic or optically Active - through a rearrangement of a-pinene oxide catalytic optically active or racemiCo can be commercially practicable.In One embodiment,The Method comprises continuously provide a-pinene oxide mixture that includes a Catalyst (S) and a Solvent (S) where the Solvent (S) has (have) a higher Boiling Point than the- with an aldehyde to folenico, sufficient conditions for porveer conversion complete, or at least partially, an oxide of a-pinene in aldehyde to canfolenico.The process also includes alcanfolenico continually bring aldehyde to the Reaction Zone, with appropriate techniques such as distillation.
