Description: technologyComment of hydrogen peroxide production, product in 50% solution state (RER): The most common technique for the production of hydrogen peroxide is the autooxidation (AO) or anthraquinone process. In a first step, hydrogen peroxide is produced by reducing alkylanthraquinone with hydrogen in the presence of a catalyst to the hydrochinone. Then the catalyst is removed and the hydrochinone is oxidised – usually with air – back to the origin quinone and in the same time hydrogen peroxide is produced. The quinones can then be re-hydrolysed again. The whole reaction takes place in a working solution that consists of a mixture of various solvents (i.e. parts are aromatic solvents). The whole process is exothermic. In a second step, hydrogen peroxide is extracted from the working solution and concentrated. Both steps are included in this dataset.

Comment: This is a market activity. Each market represents the consumption mix of a product in a given geography, connecting suppliers with consumers of the same product in the same geographical area. Markets group the producers and also the imports of the product (if relevant) within the same geographical area. They also account for transport to the consumer and for the losses during that process, when relevant. This dataset represents the supply of 1 kg of hydrogen peroxide, without water, in 50% solution state from activities that produce it within the geography RER. A regional market for Europe [RER] is motivated by the low share (in the range of 0.4%-3.2% of total trade quantities between 2010-2016) of import quantities to EU28 from outside (excluding Norway and Switzerland) the Union. In addition, the export quantities exceeded the import quantities (the ratio export/import was in the range of 5.20-28.57 in the same period).

The transport amounts are based on eurostat transport statistics for 2016 (http://ec.europa.eu/eurostat/data/database, extracted on the 2018-06-01). See exchange comments for additional details. This market is supplied by the following activities with the given share: hydrogen peroxide production, product in 50% solution state, RER: 1.0 generalComment of hydrogen peroxide production, product in 50% solution state (RER): This dataset represents the production of 1 kg of hydrogen peroxide. Hydrogen peroxide is a colourless liquid with a slightly sharp odour at higher concentrations. Due to its characteristics as a strong oxidising agent, hydrogen peroxide is widely used as a bleaching agent in the paper and the textile industry. Further important uses are e.g. wastewater treatment, disinfection applications or hydrometallurgical processes. In dilute solutions H2O2 acts as a very efficient antiseptic. This dataset is based on a study performed by EMPA and Boustead Consulting, commissioned by CEFIC, and contains data from 8 European producers of hydrogen peroxide.
