>1.which is the best method of addition.
I definitely will be looking into this method, best idea is to check Organic Synthesis on their peracetic reaction which creates trans-stilbene epoxide (sic?).
>2. What will the PH be of a freshly prepared Peracetic solution; after exact predetermined
Just work out the stoichiometry and add excess sodium bicarbonate.
>3. Chromic mentioned a fully buffered RXN. are there no adverse side Rxns with a very basic enviroment.
It won't be very basic. It will be a mixture of sodium acetate, sodium bicarbonate and water. pKa of baking soda is like 8.3 in aqueous solution.
>It is swims theory that this could speed reaction times.
Neutral peracids do break down faster than acidic ones.
>any Clarification to this proscess or better ideas for Ph Control are welcome.
Research it, experiment, research, experiment... don't give up until you're hitting your head against a brick wall.
