Hi Ecomike,
I mentioned yesterday that the nice thing about P2O is that they are not interested in just one specific end product. If the reaction generates hydrocarbons within a certain chain size the refinery will separate them into gas, diesel, fuel oil, ect.
I have to agree with you about problems with scaling up. However one usually whats a specific end product. The byproducts of a large reation could make the whole process unfeasible. This happen with one drug I know of. At the small production scale it was active, however when the company scaled up the byproducts within the preparation were killing the cell culture system. Thus one had to figure out how do redo the reaction and eliminate the toxic byproduct before the drug could move forward.
Cheers
PS the second paragraph you probably already know. It is just nice to help to inform others on this board.
