I've been thinking about this recently, and wondering if a dilute solution of Sodium borohydride might reduce the process with some of the natural musks that have a ketone group on the 3 carbon, among other things. I'm not sure how a person without a lab can get their hands on the stuff and it would probably need to be neutralized before use.
I specifically want to reduce civetone to civetol, which is also an important component of natural civet musk, though not a component of synthetic civet musk. It's been suggested that the double bond in civetone might remain intact from such a reduction, though I don't know enough about O chem to know if this is true.
The corresponding alcohols of the macro cyclic ketones are really very low in odor profile if any and have never been useful in perfumery.
I've found some analogous alcohol-musks to have a good effect (not the cyclic keytone musks specifically), and better tolerated as musks by a much wider variety of people. I agree that the smell is a lot weaker, but the animal produced them as part of its scent for a good reason. ;-)
Hello David; I am aware this is al old post but do Rose Ketones form Acetals when diluted in Perfumers alcohol ? thank youIn Chemistry "oxidation" is defined as the addition of oxygen to a molecule, or the removal of hydrogen from a molecule (there are other definitions, but this will do). It is a chemical process and so the molecule will be changed. So Ethyl Alcohol will be oxidised to Acetaldehyde, which will in turn be oxidised to Acetic Acid. Phenyl Ethyl Alcohol will be oxidised to Phenylacetaldehyde, which will in turn be oxidised to Phenylacetic Acid. It is possible to reverse this process, but it is unlikely to occur unless you radically alter the conditions.
By the way Limonene will oxidise to Carvone and Limonene oxide (mainly).
In the case of limonene, oxidation can go two different ways.For example the limonene C10H16 what it would be after oxidation ?
Ketones dissolve in alcohol and can transiently form hemiacetals. This means one molecule of alcohol can sometimes bond onto a ketone molecule. But the reaction can go both ways, and under normal conditions only a small fraction of the ketone molecules in the alcohol solution exist in the form of hemiacetal. This is known as an "equilibrium".I have no idea if rose ketones react with ethanol. In theory ketones do.
