Claim 1
Independent Claim
42 words
An odorant composition comprising an effective amount of a compound of the general formula ##STR11## wherein R represents the 2-cis or the 2-trans-buten-1-ylidene group and at least one other odorant with the exception of natural mixtures containing a compound of formula I.
Claim 2
Dependent Claim
42 words
An odorant composition comprising an effective amount of a compound of the general formula ##STR11## wherein R represents the 2-cis or the 2-trans-buten-1-ylidene group and at least one other odorant with the exception of natural mixtures containing a compound of formula I.
Claim 3
Dependent Claim
26 words
An odorant composition according to claim 1 which comprises an effective amount of a composition consisting essentially of about 15% cis/trans-1,4-epoxy-1,3,3-trimethyl-2-(2-buten-1-ylidene)-cyclohexane and about 85% trans/trans-1,4-epoxy-1, 3,3-trimethyl-2-(2-buten-1-ylidene)-cyclohexane.
Claim 4
Independent Claim
46 words
A method for improving an odorant composition which comprises adding thereto an effective amount of a compound of the general formula ##STR12## wherein R represents the 2-cis or the 2-trans buten-1-ylidene group with the exception of adding the compound as part of a naturally occurring mixture.
Claim 5
Independent Claim
46 words
A method for improving an odorant composition which comprises adding thereto an effective amount of a compound of the general formula ##STR12## wherein R represents the 2-cis or the 2-trans buten-1-ylidene group with the exception of adding the compound as part of a naturally occurring mixture.
Claim 6
Dependent Claim
23 words
The method according to claim 3 wherein there is added a composition consisting essentially of about 15% cis/trans-1, 4-epoxy-1,3,3-trimethyl-2-(2-buten-1-ylidene)-cyclohexane and about 85% trans/trans-1,4-epoxy-1,3,3-trimethyl-2-(2-buten-1-ylidene)-cyclohexane.
