Allow me to repost the link from @A_B_Dada 's original post above. Try reading this one more time with the realization this Internet post was created using Optical Character Recognition software capture of an original photocopy of this patent (microfiche?) It's full of misspellings which are actually OCR fails ...when software looked at a picture of letters/numbers and tried to convert it to ASCII text (so it can be searchable and cut/pasted).
You can start to see (many!) simple errors (misspellings) which if taken at face value might make you feel ignorant when reading this for it's technical value. Example: Search for the word "Docket" the word before Docket should always be "Attorney" Double TTs are common OCR fails like 1's and I's (ones and eyes) and 0's and O's (zeroes and Ohs)
You can get a feel for what I am trying to say looking at all the multiple ways the picture of the word Attorney was captured to text incorrectly ...translation? You almost have to translate some of this stuff, especially if it's a word you never heard before ...more likely an OCR translation error than a failure of your education Do NOT let this stop you, it is not that complicated ...ok well ...maybe a little.
Volatile ester-based flavors? The basics are simple and familiar ...apples bananas? ...most fruits have naturally occurring sugars and acids. Sugars ferment and make alcohol(s) which combine with those natural acids and makes ketones we detect with our nose as "ripening". This is done on purpose in the lab to make a small range of flavors we all know from A-Z growing up eating artificially flavored candy and other foods. We talked about Juicy Fruit as such a thing, which is just vinegar and isopentyl alcohol mixed (isopentenyl acetate) Wriggly was a newb... he just had a slamming Patent lawyer.
Organic Chemistry 101? "Organic" means carbon-based. One carbon atom has 4 places for other atoms like Oxygen, hydrogen, nitrogen etc to bond ...lets stick with gases ..one carbon bonds with 4 hydrogen atoms you have Methane gas. Take off one Hydrogen and you can add another carbon with it's remaining 3 open slots ...two carbon atoms together can now hold 6 hydrogen atoms and you have ethane gas. Pump those gases through water and they can pick up an oxygen-hydrogen and become methanol and ethanol (alcohol) Pardon my over-simplification but natural gas and vodka are pretty close.
So I added two carbons with just hydrogen ...well that just keeps going 3 4 5 6 7 8 carbons in a chain and hey now you have 8 carbons and 18 hydrogen atoms for Octane (sound familiar? major component of gasoline). Same is true for similar carbon chain acids. Many of these simple chained hydrocarbons, alcohols and acids are all naturally occurring in fruits and milk products and mix to make all things you smell (referred to in the document as C2-12).
Here's a quick simple list of the basics of making your own artificial/and familiar flavors. The Chemists at FlavorArt went to another 3-7 years of Chemistry after learning this stuff, but these are the simplest foundation. Check out how close cherry and apple are chemically. I have done this and as I said above these are all the fake overly-simplified flavors you tasted your whole life ...think Jolly Ranchers and Popsicles and flavored soda... also some of the flavors most suppressed by PDO.
I'll try and spend more time looking at the list of line items for what is most suppressed, but we may be in over our heads in terms of eJuice. The manner in which PDO supresses looks to be an advantage in some cases and can even extend shelf life for some products. A main question might be does it extend the shelf life of nicotine. I wrote this little book because the chemistry is not that mind-blowing. As @zigz said this is the 1-2 year college mark, and the most daunting part of the Patent Article is getting past all the miss-recognized (and so misspelled!) words.
I love a good puzzle..
