Abstract:
Ethylvanillin isobutyrate is a valuable new fragrance and flavor substance which, because of its extraordinary organoleptic profile and its favorable technical properties, permits hitherto unknown effects in perfumery and flavoring.
Abstract:
Unsymmetrical dihydrodithiazines of the formula ##STR1## in which one of the substituents R.sub.1 and R.sub.2 represent a C.sub.3 -C.sub.5 -alkyl group while the other is a methyl group and R.sub.3 represents a hydrogen atom, or R.sub.1 represents a methyl group and R.sub.2 and R.sub.3 together form a C.sub.3 -C.sub.4 -alkylene radical, a process for their preparation and their use as fragrances and flavorings.
