Hi Everyone,
I am pulling my hair out trying to find the answer to this question. I went to the links posted links for history, and to no avail. I've tried looking at history of egyptians, greeks etc. but their history is drinking alcohol. Does anyone have a good idea where I could start. I've tried encylopedias, no names are given. Anyone that could help it would be great.
Not to nitpick, but chemical compounds are usually said to be discovered rather than invented because, more likely than not, they can be found in nature...just not very easily.
I doubt the ancients knew anything about specific compounds, though they may well have perfected the use of several hundreds of mixtures. Even the few elemental metals that they worked with, they had no knowledge they were elements. They just treated all different materials as...well different.
The medieval alchemists did a little better. For instance with the destructive distillation of wood, they produced methanol and quickly discovered it was pretty poisonous stuff. They were also able to identify some trace products like acetone(?) and maybe acetic acid. It may be that they had made some propanol, but I highly doubt they synthesized or understood isopropanol.
Then followed much more systematic investigations, beginning early in the 19th century but catching steam only about 50 years later with Perkins and others. Still, I doubt that folks actually had made any isopropyl until perhaps pretty close to 1900. If I had to bet on a window, I'd say it happened sometime between 1890 and 1920. I'm almost positive that by the 1920s, the folks at GM and Du Pont had extracted from the hydrolysis of cellulose, every alcohol that had potential as a fuel.
Read this if you have the time : http://www.radford.edu/~wkovarik/papers/kettering.html#highp
The only way I know that IPA can be made at a reasonable yield is the pretty complex Strong-Acid Hydrolysis (aka the strong-acid process). The article above states that this process had been explored by the 20's.That's the best I can do as far as guessing goes. If you really need this info badly, look into this site :

Follow the resources there, and you may find something. But it's not going to be easy. You might try emailing a few people on the Division of History for ACS or the Society for the History of Alchemy and Chemistry.
Also, does anyone know how to find out who invented 409? again I can't find it. I even tried the free pantent site. Going nuts on research.
Formula 409 was developed by chemists at Clorox.
