巴斯夫公司、因斯布鲁克大学(位于奥地利的多恩比恩)和DeNora植物工程公司(位于德国的罗登巴赫)已经成立了一个合资公司来为一种电化学染色过程开拓市场。该过程用于纺织行业的靛青和瓮还原染料的染色。这种技术通过在含有Fe~(2+)/Fe~(3+)的溶液中通电而将染料还原为它们的水溶性形式。巴斯夫公司声称,电化学还原过程不需化学还原 BASF, the University of Innsbruck (Dornbahn, Austria) and DeNora Plant Engineering (Rodenbach, Germany) have established a joint venture to develop a market for an electrochemical dyeing process. This process is used for the dyeing of indigo and vat vat dyes in the textile industry. This technique reduces the dyes to their water-soluble form by energizing the solution containing Fe 2+ /Fe 3+ . BASF claims that the electrochemical reduction process does not require chemical reduction
