Abstract
Description
technical field
[0001] The invention relates to an analysis method for hydrogen peroxide working liquid by packed column gas chromatography. Background technique
[0002] As a green chemical, hydrogen peroxide will continue to develop vigorously as a key project during the "Tenth Five-Year Plan" period. The production method of hydrogen peroxide is mainly the anthraquinone method, and the essence of the hydrogen peroxide production process by the anthraquinone method is: tetrahydro 2-ethylanthraquinone and 2-ethylanthraquinone (hereinafter referred to as anthraquinone) as working substances , dissolved in an organic solvent to form a working solution, anthraquinone is alternately hydrogenated and oxidized, and hydrogen peroxide is generated at the same time. Whether it is the production process or the laboratory catalytic process research, it is necessary to accurately determine the concentration of tetrahydro 2-ethylanthraquinone and 2-ethylanthraquinone in the working sol...
