Nutmeg238:
Also, they give an example in US patent 2802025 where CH3COOOH is made from CH3COOH, H2O2 and H2SO4 which are allowed to come to equilibrium in 12 to 16 hr.  See also US patent 5098598 which discusses the stability of percarboxylic acids and US patent 4168274 which discloses a continuous epoxidation process which uses aqueous and organic phases.  Also, search class 562 subclasses 2, 4 and 6 which covers percarboxylic acids and epoxidation.  You can search it online at http://www.uspto.gov or if you're near the patent office go there and you can search all the way back to patent number 1. If you're near a patent office in another country they might have US patents.........
