Peracetic acid (also known as peroxyacetic acid, or PAA), is an organic compound with the formula CH 3 CO 3 H. This organic peroxide is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid.It can be highly corrosive.. Peracetic acid is a weaker acid than the parent acetic acid…
The invention relates to a combined process for the manufacture of feed grade dicalcium phosphate and pure phosphoric acid. The process comprises the reaction of an excess of phosphate rock with aqueous solutions of a mineral acid selected from hydrochloric acid, phosphoric acid and nitric acid, characterized by the fact that the free acidity of the dissolution liquor does not exceed 60% and ...
The invention provides a continuous process for producing a pure grade of acrylic acid having residual aldehyde levels under 10 parts per million. The process applies two groups of amines sequentially and continuously in selectively reducing acrolein and furfural and may be advantageously conducted in the presence of maleic acid and maleic anhydride impurities.
