Abstract
The invention relates to a production technology of high purity peroxyacetic acid, comprising the following steps: (1) adding submicron ultrafine magnesium oxide in peroxyacetic acid containing sulfuric acid; (2) stirring the mixture at the temperature of 40-80 DEG C, allowing magnesium oxide to react with peroxyacetic acid to obtain magnesium sulfate; (3) using nano-ceramic film to separate magnesium sulfate from peroxyacetic acid at the temperature of 0-40 DEG C; and (4) acquiring high purity peroxyacetic acid without strong-acid catalyst. Compared with the prior art, the invention has the advantages of high quality, popularity, low energy consumption, safety, environmental conservation, small investment and the like.
Description
Technical field
The present invention relates to a kind of production technique of high-purity Peracetic Acid, especially relate to the production technique of high-purity Peracetic Acid product of strong acid catalysts such as a kind of not sulfur acid.
Background technology
It is main raw material that the Peracetic Acid product adopts hydrogen peroxide, acetate usually, and strong acid such as sulfuric acid are as the method production of synthetic catalyst.Owing to the form of strong acid such as sulfuric acid in the Peracetic Acid product with impurity exists, produced three big defectives: 1. corrodibility is big, 2. influences the purity of subsequent product, 3. produces reversible reaction, and Peracetic Acid content and quality guaranteed period reduce.Therefore the Peracetic Acid product is limited in the application of scientific research fields such as high-end health care, food, chemical industry, pharmacy.High-purity Peracetic Acid product processes of strong acid catalyst such as sulfur acid does not have secondary solvent extraction process, second distillation method etc., but be not with aforesaid method can both economy the high-purity Peracetic Acid that obtains or obtain of safety can be general at scientific research fields such as high-end health care, food, chemical industry, pharmacy.Make the high-purity Peracetic Acid that obtains to be limited to specific use range as the residual solvent of solvent extration, have the danger of high energy consumption and blast as distillation method, it is too huge and produce more dangerous waste liquid two big defectives that secondary solvent extraction process, second distillation method have facility investment simultaneously.
Summary of the invention
Purpose of the present invention is exactly the production technique that high-purity Peracetic Acid of a kind of high quality, versatility, less energy-consumption, security, the feature of environmental protection, less investment is provided for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of production technique of high-purity Peracetic Acid is characterized in that this technology may further comprise the steps:
(1) magnesium oxide is joined contains in the vitriolic Peracetic Acid;
(2) 40 ℃～80 ℃ stirrings, magnesium oxide and sulfuric acid reaction generate sal epsom;
(3) at 0 ℃～40 ℃ with nano ceramics membrane sepn sal epsom and Peracetic Acid;
(4) do not contained high-purity Peracetic Acid product of strong acid catalyst.
The mass ratio of described magnesium oxide of step (1) and Peracetic Acid is 1: (10～100).
The described magnesium oxide of step (1) is the submicron super fine magnesia.
The massfraction of Peracetic Acid is greater than 50% in the described high-purity Peracetic Acid product of step (4), vitriolic content in vitriol less than 0.0001%.
Compared with prior art, the production technique of high-purity Peracetic Acid product of the strong acid catalysts such as not sulfur acid of the present invention exploitation has the advantage of high quality, versatility, less energy-consumption, security, the feature of environmental protection, less investment.The present invention is fit to produce not high-purity Peracetic Acid product of strong acid catalyst such as sulfur acid.Adopt gained of the present invention not high-purity Peracetic Acid product of strong acid catalyst such as sulfur acid meet following index: Peracetic Acid content is greater than 50%, and sulfuric acid (in vitriol) is less than 0.0001%.Have simultaneously corrodibility little, do not influence the purity of subsequent product, do not produce reversible reaction, Peracetic Acid content is guaranteed, the quality guaranteed period improves, facility investment is little and do not produce the advantage of dangerous waste liquid.Product is applicable to scientific research fields such as high-end health care, food, chemical industry, pharmacy.
