| abstract |
As novel compositions of matter, Beta -alkoxy alde-hydes, such as Beta -isobutoxypivaladehyde, which, being like most aldehydes, are odoriferous compounds useable as aids in the composition of perfumes. The novel Beta -alkoxy aldehydes are also useful intermediates in the preparation of useful alcohols, carboxy acids, carboxy amides, etc. The novel Beta -alkoxy aldehydes of the invention are prepared by the unique vapor phase isomerization of meta-dioxanes catalyzed by weakly acidic surfaces such as pumice and silica gel. |
