Abstract
Abstract Described is a process for preparing hydrogenated derivatives of 2,6,6-trimethyl cyclohexene derivatives by means of treating said derivatives with hydrogen in the presence of a supported palladium catalyst such as palladium-on-calcium carbonate or palladium-on-barium sulfate in the presence of a quinoline activator. The resulting products are useful for their organoleptic properties as foodstuff flavorants and flavor enhancers, perfume composition ingredients, perfumed article ingredients and tobacco flavorants and flavor enhancers.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
A dryer added fabric softener article comprising a substrate, coated on said substrate a coating and coated on said substrate coating an outer coating and intimately admixed with said outer coating at least one substance selected from the group consisting of: (i) the compound having the structure: ##STR88## (ii) the compound having the structure: ##STR89## (iii) a mixture of compounds having the structures: ##STR90## (iv) a mixture of compounds having the structures: ##STR91## said substance being in such an amount that when the dryer-added fabric softener article is contacted with a clothing batch an aroma is imparted in a pleasant manner to the head space in the dryer on operation thereof using the said dryer-added fabric softening article.
Claim 2
Dependent Claim
118 words
A dryer added fabric softener article comprising a substrate, coated on said substrate a coating and coated on said substrate coating an outer coating and intimately admixed with said outer coating at least one substance selected from the group consisting of: (i) the compound having the structure: ##STR88## (ii) the compound having the structure: ##STR89## (iii) a mixture of compounds having the structures: ##STR90## (iv) a mixture of compounds having the structures: ##STR91## said substance being in such an amount that when the dryer-added fabric softener article is contacted with a clothing batch an aroma is imparted in a pleasant manner to the head space in the dryer on operation thereof using the said dryer-added fabric softening article.
Claim 3
Dependent Claim
154 words
A dryer-added fabric softener article comprising a substrate, coated on said substrate a substrate coating and coated on said substrate coating an outer coating and intimately admixed with said outer coating a product produced according to the process comprising the step of intimately admixing hydrogen with at least one compound defined by the structure: ##STR92## wherein in the cyclohexene moiety one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is either a carbon-carbon double bond or a carbon-carbon single bond, said reaction taking place in the presence of a suspended palladium catalyst, said product-by-process being present in said outer coating in such a quantity that when said dryer-added fabric softener article is in contact with a clothing batch in a dryer, an aroma is imparted in a pleasant manner to the head space in the dryer on operation thereof using the said dryer-added fabric softener article.
Claim 4
Dependent Claim
154 words
A dryer-added fabric softener article comprising a substrate, coated on said substrate a substrate coating and coated on said substrate coating an outer coating and intimately admixed with said outer coating a product produced according to the process comprising the step of intimately admixing hydrogen with at least one compound defined by the structure: ##STR92## wherein in the cyclohexene moiety one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is either a carbon-carbon double bond or a carbon-carbon single bond, said reaction taking place in the presence of a suspended palladium catalyst, said product-by-process being present in said outer coating in such a quantity that when said dryer-added fabric softener article is in contact with a clothing batch in a dryer, an aroma is imparted in a pleasant manner to the head space in the dryer on operation thereof using the said dryer-added fabric softener article.
