Abstract
The present invention relates to new process of preparing peroxy acetic acid serving as bleaching agent, pesticide and bactericide. Acetic anhydride as the material is oxidized with peroxide solution of 10-50 % concentration through reaction at the temperature controlled in 20-60 deg.c for 4 hr to produce peroxy acetic acid.
Description
Technical field
The present invention relates to a kind of SYNTHETIC OPTICAL WHITNER, new preparation process of in weaving, being used as in hospital as the new preparation process, particularly Peracetic Acid of the sterilant of sterilant.
Background technology
At present, industrial synthetic Peracetic Acid method remains two kinds of hydrogen peroxide and acetaldehyde oxidations, though these two kinds of methods have had new development and improvement at present, need to adopt the strong acid class to do catalyzer and condition of high voltage, not only increase cost and increased the three wastes and danger.Though this technology also is peroxide oxidation method but to have adopted aceticanhydride be raw material as long as single step reaction has at normal temperatures and pressures been avoided deficiency in the former technology, has improved Working environment and has reduced production costs.
Summary of the invention
It is not enough in order to solve in the former technology that purpose of the present invention is exactly, and a kind of safe and convenient and technology that cost is low is provided, and is that the direct and superoxide of raw material reacts the generation Peracetic Acid at normal temperatures and pressures with aceticanhydride.
The technology of the present invention solution:
A kind of technique for preparing peroxyacetic acid, its feature are to be raw material with the aceticanhydride, with superoxide oxidizing reaction generation in the 4 hours at a certain temperature Peracetic Acid of proper concn.The superoxide of proper concn refers to react the superoxide that initial peroxide level is 10-50%, and certain temperature refers to that temperature of reaction is controlled at 20-60 ℃.
Embodiment
A kind of technique for preparing peroxyacetic acid, its feature are to be raw material with the aceticanhydride, are added drop-wise in the aceticanhydride with the 10-50% superoxide, and the control rate of addition makes temperature of reaction remain on 20-60 ℃, and oxidizing reaction generated Peracetic Acid in 4 hours under this temperature.
Example one
Under fully stirring, the hydrogen peroxide of 100g30% is added drop-wise in the 450g aceticanhydride the outer cooling of control feed rate and bottle, make temperature of reaction dimension built in 40 ℃, reinforced finishing was 40 ℃ of following stirring reactions 4 hours, spend the night in the room temperature placement, the Peracetic Acid concentration that makes is 1mol/L.
Embodiment two
Under fully stirring, the chlorine peroxide of 303g30% is added drop-wise in the 450g aceticanhydride the outer cooling of control feed rate and bottle, make temperature of reaction dimension built in 40 ℃, reinforced finishing was 40 ℃ of following stirring reactions 4 hours, spend the night in the room temperature placement, the Peracetic Acid concentration that makes is 1mol/L.
Implement three
Under fully stirring, the hydrogen peroxide of 75g40% is added drop-wise in the 450g aceticanhydride the outer cooling of control feed rate and bottle, make temperature of reaction dimension built in 30 ℃, reinforced finishing was 30 ℃ of following stirring reactions 4 hours, spend the night in the room temperature placement, the Peracetic Acid concentration that makes is 1mol/L.
Claims (4)
1, a kind of technique for preparing peroxyacetic acid, its feature are to be raw material with the aceticanhydride, with superoxide oxidizing reaction generation in the 4 hours at a certain temperature Peracetic Acid of proper concn.The superoxide of proper concn refers to react the superoxide that initial peroxide level is 10-50%, and certain temperature refers to that temperature of reaction is controlled at 20-60 ℃.
