Abstract

"COMPOSIçãO QUìMICA E PROCESSO". A presente invenção se refere a uma composição aquosa de até cerca de 90% em peso de peróxido de hidrogênio, compreendendo cerca de 0,05 a cerca de 20 mmol/kg H~ 2~O~ 2~ de ácido amino tri(metilenofosfónico) ou sais ou produtos de decomposição do mesmo e um inibidor de corrosão, sendo substancialmente livre de ou contendo menos de cerca de 0,1 mol/1 de íons clorato, tendo um teor de estanho de 0 a cerca de 100 mg/kg H~ 2~O~ 2~, e tendo um teor de cloreto inferior a cerca de 10 mg Cl^ -^/kg H~ 2~O~ 2~. A invenção se refere também a um processo para produção de dióxido de cloro em que a dita composição é utilizada como material de alimentação."CHEMICAL COMPOSITION AND PROCESS". The present invention relates to an aqueous composition of up to about 90 wt% hydrogen peroxide, comprising about 0.05 to about 20 mmol / kg H ~ 2 ~ O ~ 2 ~ amino (tri (methylenephosphonic)) amino acid or salts or decomposition products thereof and a corrosion inhibitor, being substantially free of or containing less than about 0.1 mol / l chlorate ions, having a tin content of 0 to about 100 mg / kg H 2. 2 ~ O ~ 2 ~, and having a chloride content of less than about 10 mg. The invention also relates to a process for producing chlorine dioxide wherein said composition is used as a feed material.
