For cheaper, greener and more efficient production of dyes, ThalesNano has the reactor range to help you to get the results you want.
Hydrogenation is a very important process for the dye industry. The reduction of double bonds, aromatic rings, nitro or azo groups can drastically affect the colour or the intensity of the colour. It is also a very clean and efficient process. The main drawback is the safe utilization of the hydrogen gas. With the H-Cube Series, dyes can be reacted up to 150°C and 100 bar safely, because the hydrogen is generated from the electrolysis of water. No hydrogen cylinders or special facilities are required.
