The manipulation of the pH levels to shift the ABE reactions to buytol alcohol is what is new.

Yes, I should have been more clear in my wording. Many chemicals have been made from biological processes long before they were made from purely chemical processes, but the claimed ability to make it in commercial quantities from biomass is new.

It was made commercially that way before the use of oil-derived hydrocarbons.

The new patent is based on keeping the biological portion in the butynol side of the reaction.

(I looked up their patent in the past....I don't want to spend the time looking it up again, so perhaps someone here will)

No need to look up the patent. They summarize the history of butanol, with links to additional information (and to the patent) at http://www.butanol.com/.
