Publication date: Oct. 13, 2015
Assignee: Segetis, Inc.

“According to this patent, there is a need for renewably sourced solvents combine one or more attributes such as solubility with one or more components, reactivity, volatility, toxicity, environmental profile and cost. A further advantage would be if such solvents could be modified to adjust the chemical and physical properties to meet the needs of specific applications.

The inventors on this patent have discovered long-chain ketal adducts of ketocarboxy esters, in particular levulinate esters. Such materials impart various properties that make them useful as solvents for a variety of applications including fragrances, adhesives, sealants, cleaning compositions, personal care compositions and more.”

3-Novel F&F Fragrance Material

This discovery is 3,6,7-trimethyl-6-octen-1-in-3-ol, as a new F&F formulation.

“In the flavor and fragrance industry there is always a need for compounds that enhance, modify, improve or otherwise positively influence an odor note, thereby giving perfumers the ability to create new fragrances. In relation, the present inventors have discovered a new compound that is useful as a flavor and fragrance material, a depiction of which is disclosed in this patent.

The new compound, 3,6,7-trimethyl-6-octen-1-in-3-ol, is manufactured by: a) ethinylating 5,6-dimethyl-5-hepten-2-on to 3,6,7-trimethyl-6-octen-1-in-3-ol; b) acylating 3,6,7-trimethyl-6-octen-1-in-3-ol to 3,6,7-trimethyl-6-octen-1-in-3-yl acetate; and c) hydrogenating the C≡C triple bond 3,6,7-trimethyl-6-octen-1-in-3-yl acetate to the saturated C—C bond in the presence of a Lindlar catalyst, which leads to the final compound.

Two processing examples are given to create this material. The first produces an odor descriptor of: plant; hop; wood; leek/field garlic; inside of rubber gloves; sweetish; and sourish with an intensity = 5. The second can be described as: balsamic; creamy; dry stored wood; and dry leaves with an intensity = 4.”
