Abstract
Described is the use in augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes or chewing tobaccos comprising the step of adding to a foodstuff, toothpaste, chewing gum or chewing tobacco an aroma or taste augmenting or enhancing quantity of at least one acylated diisoamylene derivative defined according to the structure: ##STR1## wherein R.sub.4 ' represents C.sub.1 -C.sub.3 lower alkyl; wherein one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines represent carbon-carbon single bonds.
Claims5
A process for augmenting or enhancing the aroma or taste of a foodstuff, chewing gum or toothpaste comprising the step of adding to a foodstuff, toothpaste or chewing gum from 0.05 parts per million up to about 100 parts per million based on the weight of the total foodstuff, chewing gum or toothpaste composition of a product containing a major proportion of a mixture defined according to the structure:
- ##STR194## wherein in each of the molecules of the mixture, one of the dashed lines is a carbon-carbon double bond and each of the other of the dashed lines is a carbon-carbon single bond, produced according to the process of:
- (i) dimerizing 2-methyl-2-butene in the presence of an acid catalyst to produce a diisoamylene composition;
- (ii) reacting the resulting diisoamylene composition with acetic anhydride in the presence of a boron trifluoride diethyletherate catalyst at a reaction temperature of 80.degree.-85.degree. C.;
- and
- (iii) distilling the resulting product at a vapor temperature in the range of from 30.degree. C. up to 80.degree. C. and a pressure of from 3 mm/Hg pressure up to 5 mm/Hg pressure.
A process for augmenting or enhancing the aroma or taste of a foodstuff, chewing gum or toothpaste comprising the step of adding to a foodstuff, toothpaste or chewing gum from 0.05 parts per million up to about 100 parts per million based on the weight of the total foodstuff, chewing gum or toothpaste composition of a product containing a major proportion of a mixture defined according to the structure:
- ##STR195## wherein in each of the molecules of the mixture, one of the dashed lines is a carbon-carbon double bond and each of the other of the dashed lines is a carbon-carbon single bond, produced according to the process of:
- (i) dimerizing 2-methyl-2-butene in the presence of an acid catalyst to produce a diisoamylene composition;
- (ii) reacting the resulting diisoamylene composition with acetic anhydride in the presence of a methane sulfonic acid catalyst at a temperature of 65.degree.-80.degree. C.;
- and
- (iii) distilling the resulting product at a vapor temperature in the range of 52.degree.-61.degree. C.;
- a liquid temperature in the range of from 80.degree.-134.degree. C. and a pressure of 1 mm/Hg.
A process for augmenting or enhancing the aroma or taste of a foodstuff, chewing gum or toothpaste comprising the step of adding to a foodstuff, toothpaste or chewing gum from 0.05 parts per million up to about 100 parts per million based on the weight of the total foodstuff, chewing gum or toothpaste composition of a product containing a major proportion of a mixture defined according to the structure:
- ##STR196## wherein in each of the molecules of the mixture, one of the dashed lines is a carbon-carbon double bond and each of the other of the dashed lines is a carbon-carbon single bond, produced according to the process of:
- (i) dimerizing 2-methyl-2-butene in the presence of an acid catalyst to produce a diisoamylene composition;
- (ii) reacting the resulting diisoamylene composition with acetic anhydride in the presence of a boron trifluoride diethyletherate catalyst at reaction temperature of 60.degree. C.;
- and
- (iii) distilling the resulting product at a vapor temperature in the range of from 50.degree. C. up to 90.degree. C. and a liquid temperature of from 60.degree. C. up to 115.degree. C. and a pressure of from 1.4 up to 3.0 mm/Hg.
A process for augmenting or enhancing the aroma or taste of a foodstuff, chewing gum or toothpaste comprising the step of adding to a foodstuff, chewing gum or toothpaste composition from 0.05 parts per million up to about 100 parts per million based on the total weight of foodstuff, toothpaste or chewing gum composition of a mixture containing a major proportion of compounds defined according to the structure:
- ##STR197## wherein in the mixture, in each of the molecules one of the dashed lines is a carbon-carbon double bond and each of the other of the dashed lines is a carbon-carbon single bond produced according to the process of:
- (i) dimerizing 2-methyl-2-butene in the presence of an acid catalyst to form a diisoamylene composition;
- (ii) reacting the resulting diisoamylene composition with n-butyric anhydride in the presence of boron trifluoride at a temperature of 65.degree. C.;
- and
- (iii) distilling the reaction product at a vapor temperature in the range of from 47.degree. C. up to 84.degree. C.;
- a liquid temperature of from 105.degree. C. up to 220.degree. C. and a pressure of from 1.0 to 1.8 mm/Hg.
A process for augmenting or enhancing the aroma or taste of a foodstuff, chewing gum or toothpaste comprising the step of adding to a foodstuff, chewing gum or toothpaste composition from 0.05 parts per million up to 100 parts per million based on the total composition of said foodstuff, chewing gum or toothpaste composition of a mixture containing a major proportion of compounds defined according to the structure:
- ##STR198## wherein in the mixture, in each of the molecules, one of the dashed lines represents a carbon-carbon double bond and each of the other of the dashed lines represent carbon-carbon single bonds, produced according to the process of:
