Latest Patents
Bettge's latest patents include a process for purifying polyethers and a method for producing purified hydroxy-functional polyether compounds. The first patent focuses on several innovative aspects to enhance the coalescing process for purifying crude polyether. This includes the use of particulate zirconium dioxide as a coalescing medium, the recovery and recycling of alkali metal catalysts, and a two-phase purification process that effectively removes water while preserving valuable components. Additionally, the process emphasizes minimizing impurities by mixing crude polyether with water before coalescing and conducting the process under a non-oxidizing atmosphere.
The second patent addresses the reduction of propenyl ethers in hydroxy-functional polyethers. This is achieved by contacting the polyether with an acid ion exchange resin, which converts some propenyl ethers to propionaldehyde in the presence of water. The process may also involve treating the polyether with an epoxy compound to reduce acidity.
