Phosphoric-carboxylic acid anhydrides |
| abstract |
Peroxy acids are prepared by perhydrolysis with highly concentrated hydrogen peroxide of a mixed anhydride of an appropriate carboxylic acid such as a diethyl phosphoriccarboxylic acid anhydride. Although perhydrolysis is usually effected by catalysis with methanesulfonic acid, catalysis was not required in at least one case. Both aliphatic and aromatic peroxy acids containing either electron-donating or electronaccepting groups can be prepared indicating that the process of the invention is general in scope and is utilizable with compounds having a broad range of carbon chain lengths. Yields of peroxy acids above 70 percent are easily obtained. |
