Method for preparing peroxyacetic acid and improving stability of peroxyacetic acid by adopting heterogeneous catalyst |
| abstract |
The invention provides a method for preparing peroxyacetic acid by adopting a heterogeneous catalyst, which is characterized in that attapulgite is subjected to acid activation and peroxide activation and then reacts with organic matters containing sulfonic groups to prepare an attapulgite-loaded sulfonic group super acid catalyst; the supported super acidic catalyst is used for catalyzing hydrogen peroxide and acetic acid to react to prepare the peroxyacetic acid, the reaction condition of the catalytic reaction system is mild, the catalyst can be recycled, the corrosion of equipment is low, and the product purity is high. The invention also provides a composite stabilizer suitable for high-concentration peroxyacetic acid and low-concentration peroxyacetic acid, and the storage time of the peroxyacetic acid can be obviously prolonged after the stabilizer is added. |
