Abstract: Described is the compound having the structure: ##STR1## which is used as an intermediate in preparing compounds having organoleptic properties for augmenting or enhancing the aroma or taste of consumable materials, which compounds have the structures: ##STR2##

Abstract: Described are compounds covered by the generic structure: ##STR1## where one, two or all of R.sub.1, R.sub.2 and R.sub.3 are the same or different and each represents hydrogen or lower alkyl of from 1 up to 3 carbon atoms; a process for preparing same using compounds having the generic structure: ##STR2## where one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines represents carbon-carbon single bonds and organoleptic uses thereof in perfumes, colognes, perfumed articles such as anionic, cationic and non-ionic detergents, cosmetic powders and dryer-added fabric softener articles, as well as in smoking tobaccos and smoking tobacco articles, e.g., the body of smoking tobacco, the wrapper or the filter therefor.

Abstract: Described is a process for augmenting or enhancing the aroma of a solid or liquid anionic, cationic or nonionic detergent comprising the step of adding in an aroma augmenting or enhancing quantity to a solid or liquid anionic, cationic or nonionic detergent base at least one tricyclic ketone having the structure: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each represents hydrogen or C.sub.1 --C.sub.3 lower alkyl.

Abstract: Described in a process for augmenting or enhancing the aroma or taste of a smoking tobacco comprising the step of adding to a smoking tobacco an aroma or taste augmenting or enhancing quantity of at least one tricyclic ketone having the structure: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each represents hydrogen or C.sub.1 -C.sub.3 lower alkyl.

Abstract: A fluid bed reactor including a first, upstream reaction zone having a fluidized bed of particles and a second, downstream heat recovery zone having a fluidized bed of particles. The reactor is designed adjacent the heat recovery zone to withdraw heat from the heat recovery zone at a temperature lower than the temperature in the reaction zone. In operation, the particles in the heat recovery zone cool and quench the effluent from the reaction zone so as to remove fines and volatile elutriates therefrom, rendering the effluent less corrosive and preventing back or side reactions.
