Latest Patents

Li Wan's latest patents include a method for producing vegetable oil polyol and a method for preparing high-quality epoxidized fatty acid ester using a micro-reaction device. The vegetable oil polyol preparation method involves allylic oxidation treatment of vegetable oil, which increases the hydroxyl group content in the product. This method also combines epoxidation and ring-opening in a single step, resulting in a novel vegetable oil polyol that can be used in the production of polyurethane foam materials. The advantages of this method include simple operation, low energy consumption, and a reduced occurrence of side reactions.

The second patent focuses on a method for preparing high-quality epoxidized fatty acid ester. This process utilizes a micro-reaction device, where an aqueous hydrogen peroxide solution and a carboxylic acid are mixed in a first micro-mixer. The output material is then combined with an unsaturated fatty acid ester in a second micro-mixer, followed by a complete reaction in a second micro-reactor. The final product is obtained through water rinsing and drying of the organic phase.
