The document describes a process for preparing polyether alcohols, specifically focusing on the ethoxylation of fatty alcohols. This process is optimized for customer benefit and is applicable to reactions such as ethoxylations, peroxide reactions, diazotizations, and nitrations. These reactions are characterized by high reaction enthalpies and require careful attention to process safety due to the chemicals involved.
The Miprowa® Lab system is highlighted as a solution for conducting typical reactions like ethoxylation, peroxide reactions, diazotization, and nitration. The system combines specific reactors with suitable pumps and peripherals, which have been proven effective in various customer projects.
- Media-wetted materials include Hastelloy® C22/C276, Alloy 625, Stainless Steel 316, and FFKM.
- Residence time is between 10 to 20 seconds.
- Volume flow ranges from 3 to 903 mL/min.
- Reactor volume is small, allowing for high pressures and temperatures.
- Pressure limit is between 45 to 75 bar.
- Temperature range is from 10 to 200 °C.
- Ethylene oxide (EO) can be used in a liquified form.
- Small reactor volumes facilitate high pressures and temperatures.
- Fast screening of reaction parameters is possible due to short residence times.
- High degree of automation enhances process safety.
- The feed of reactants is critical, and reliable pumps are essential for success.
The document emphasizes the importance of reliable equipment and process optimization for safe and efficient chemical reactions. The Miprowa® Lab system offers a robust solution for handling complex reactions with high safety and efficiency.

System Solution: Miprowa® Lab Typical reactions : ethoxylation, peroxide reactions, diazotization, nitration, etc. Based on our experiences with a large number of different customer projects over many years we have come up with several reactor set-ups combining specific reactors from our portfolio with suitable pumps and other peripherals. These equipment combinations have already proven their usefulness in the field for certain types of reactions and are optimized for customer benefit. For applications like ethoxylations, peroxide reactions, diazitizations and nitrations the challenges lie in very high reaction enthalpies, and process safety due to the chemicals involved. Example: Ethoxylation of fatty alcohols OH R Process for preparing polyether alcohols
