METHOD FOR PRODUCING PEROXYCARBOXYLIC ACID SOLUTIONS, ESPECIALLY EQUILIBRIUM PERACETIC ACID AND PERPROPIONIC ACID |
摘要 |
The invention relates to a method for producing a peroxyacetic acid or peroxypropionic acid solution by reacting acetic acid or propionic acid with hydrogen peroxide in the presence of a polyphosphoric acid catalyst. The catalyst used in the inventive method is a water-free solution that is obtained by dissolving 0.1 to 99 % by weight, especially 1 to 35 % by weight (based on the solution) of a polyphosphoric acid in the carboxylic acid that is to be converted to the peroxycarboxylic acid. The catalyst solution is preferably produced using molten polyphosphoric acid on the site of production of the same. |
